To the Commission:
On April 19, 1940, there was a derailment of a passenger train
on the New York Central Railroad at Little Falls, N.Y., which
resulted in the death of 26 passengers, 2 Pullman porters,
1 train porter, and 2 train-service employees, and the injury
of 47 passengers, 1 Pullman porter, 2 dining-car employees,
and 1 employee on duty. This accident was investigated in
conjunction with the New York State Public Service Commission.
Location and Method of Operation
This accident occurred on the Mohawk Division which extends between Albany and
Kirkville, N.Y., a distance of 136.76 miles. In the vicinity
of the point of accident this is a four-track line over
which trains are operated with the current of traffic by an
automatic block-signal and automatic train-stop system; signal
indications supersede time-table superiority. The main tracks
from south to north are: No. 2, east-ward passenger; No. 1,
westward passenger; No. 3, westward freight; No. 4, eastward
freight. The accident occurred on track No. 1 at a point 2,875
feet east of the station at Little Falls. Approaching this
point from the east on track No. 1 there is a series of curves
and tangents followed, in succession, by a compound curve
to the right 1,932 feet in length having a maximum curvature
of l degree 52'35", a tangent 1,193 feet in length and a 7
degree 24'curve to the left 856 feet in length. The derailment
occurred on this latter curve, known as Gulf Curve, at a point 458 feet
from its eastern end. The grade varies between 0.26 and 0.50
percent ascending westward a distance of 8,600 feet, and
following this gradient there is a vertical curve a distance
of 200 feet to the point of accident and 200 feet beyond.
In the vicinity of the point of accident the tracks are laid on a side-hill cut and
parallel generally the north shore of the Mohawk River; the
rails of track No. 1 are approximately 48 feet above the river.
At the north a rock cliff parallels the tracks a considerable
distance, and at the east end of Gulf Curve the cliff
is broken by a valley extending northward. Bridge No. 456,
on which are laid the four main tracks, is located about 550
feet west of the east end of Gulf Curve, is 37 feet 9 inches
in length, of girder construction, and provides an underpass
for Mohawk Turnpike. Mohawk Turnpike extends under the tracks
at a depth of 16 feet and at an angle of about 30 degrees;
immediately north of the tracks it turns westward, parallels
the tracks, and is designated as East Main Street. At a point
304 feet west of the point of accident the grade of East Main
Street rises to a level with the rails in track No. 1. A rock
pinnacle rises abruptly to a height of 14.57 feet between track No. 4 and East Main
Street at a point about 396 feet west of the point of accident.
Inv. No. 2423 New York Central R.R. Little Falls, N. Y. April 19, 1940
The track, structure consists of 127-pound rail, 39 feet in length,
laid on an average of 24 treated oak ties to the rail length;
it is fully tie-plated with double-shoulder canted tie-plates
spiked with two rail spikes and two lag spikes per plate, and
is provided with eight rail anchors and five gage rods per rail
length; it is equipped with 6-hole toeless angle bars 36 inches
in length, is laid on 20 inches of crushed rock ballast, and is
well maintained. The rail was laid new in June 1939, and was
spaced in August 1939. The superelevation of track No. 1 at the
point of accident was 8 inches. The north rail of the spiral at
the east end of the curve rose from level to a superelevation
of 8 inches in a distance of about 200 feet. The gage
varied between 4 feet 8-7/16 inches and 4 feet 8-9/16 inches.
Automatic signals 21421 and 21531, which govern
westward movements on track No. 1, are located 9,046 and 3,086
feet, respectively, east of the point of accident. Signal 21421
is a 2-unit, color-light, searchlight signal; signal 21531
is a 2-unit, upper-quadrant, semaphore signal; both signals are
approach lighted. The most favorable indication displayed by
these signals is in accordance with Rule 281A, which provides:
Night Aspect Indication
Green-over-yellow Proceed Approaching Second
(Staggered) Signal At Medium Speed
Because of this indication, an engineman must operate the forestalling device in
order to prevent automatic
train-stop brake applications at these signal locations.
Medium speed is defined as: A speed not exceeding thirty miles per hour.
The automatic train-stop system is of the intermittent-inductive type and
engines are equipped with forestalling devices. When a brake
application is forestalled by an engineman, the train may
proceed under his control in accordance with operating rules.
Rules for enginemen and firemen for the operation of intermittent-inductive
automatic train-stop read in whole or in part as follows:
Rule 6. Enginemen must not forestall until after signal indication
has been observed and is being obeyed.
Rule 7. Enginemen, after complying with Rule 6 may forestall at an
inductor, to avoid the automatic stop brake application--
(a) When running forward with current of traffic at signal which displays indication other
than "Proceed" or "Proceed at Medium Speed."
* * *
Rule D-251, of the operating rules, reads as follows:
D-251. On portions of the road so specified on the timetable, trains
will run with the current of traffic by block
signals whose indications will supersede timetable superiority.
Time-table special instruction D-251 reads in part as follows:
D-251. MOVEMENT OF TRAINS WITH THE CURRENT OF TRAFFIC ON TWO OR MORE TRACKS BY BLOCK SIGNALS.
Between Croton-on-Hudson and Kirkville.
The maximum authorized speed on track No. 1 in the vicinity of the point of accident is 45
miles per hour. A speed board bearing the words, "SPEED LIMIT,
GULF CURVE, 45 MILES, TRACK NO. 1," is installed on the south
bent of the signal bridge located 3,086 feet east of the point
of accident; it is attached to the bridge 10.38 feet higher
than the rails and is lettered in black on a yellow background.
A flange lubricator is located on the north rail of track
No. 1 at a point 134 feet east of the east end of Gulf Curve.
Mile Post 216 is located 396 feet west of the point of accident.
The weather was cloudy at the time of the accident, which occurred about 11:33 p.m.
No. 19, a first-class west-bound passenger train, with Conductor Grattan and Engineman Earl
in charge, and with Road Foreman of Engines Bayreuther also
on the engine, consisted of engine 5315, of the 4-6-4 type,
one express car, one baggage car, two coaches, four Pullman
sleeping cars, one dining car, five Pullman sleeping cars,
and one coach, in the order named; all cars were of steel
construction. This train departed from Albany, 73.49 miles east
of Little Falls, at 10:09 p.m., according to the train sheet,
21 minutes late, passed Fonda, the last place where time
is shown 30.17 miles east of Little Falls, at 11:07 p.m.,
23 minutes late, passed St. Johnsville, 9.73 miles east
of Little Falls, at 11:25 p.m., and while moving at a speed of
59 miles per hour, as indicated by the speed-recorder tape with
which engine 5315 was equipped, be-came derailed on Gulf Curve.
After becoming derailed, engine 5315 continued a distance
of 396 feet diagonally across tracks Nos. 3 and 4 and stopped
on its right side against the pinnacle of rock which rises
between track No. 4 and East Main Street. The engine stopped
with the front end of the smokebox on track No. 4 and the
rear end of the boiler suspended on top of the rock pinnacle;
the boiler lay at an angle of about 30 degrees to the line
of track and the rear end was about 15 feet above the rails.
Rock penetrated the firebox wrapper sheet just in front
of the backhead, and the crown sheet and the right side-sheet

Inv. No. 2423 New York Central R.R. Little Falls, N.Y. April 19, 1940
The employees killed were the engineman and the fireman,
and the employee injured was the road foreman of engines.
Summary of Evidence
Road Foreman of Engines Bayreuther stated that he inspected engine 5315 before No.
19 departed from Albany; the engine was in good condition. The
air brakes were tested at Albany, a running test was made soon
after leaving that point, a stop was made at Schenectady,
the brakes were used to control, the speed of the
train at several points where there were speed restrictions,
and in each instance the brakes functioned properly.
Approaching the point of accident there was
nothing unusual in the action of the engine, and the speed was
74 miles per hour. He said that he and the fireman called the
indications of signals 21421 and 21531, which were displaying
green-over-yellow aspects, and the engineman responded.
Soon after the engine passed signal 21421 the engineman
left his seat and examined the depth of water in the
tender by opening a gauge cock in the left wing of the cistern
and then resumed his usual position on the right seat-box.
Between signals 21421 and 21531 the speed of the train seemed to
be reduced as a result of the ascending grade. The engineman
forestalled at both signals and the whistle in the cab sounded.
After forestalling for signal 21531 the engineman made a
brake-pipe reduction which did not seem long enough to indicate
a proper brake-pipe reduction for the speed of the train and
the distance to the point of speed restriction on Gulf Curve.
The road foreman of engines said that usually a 14 or 15-pound,
reduction is made to control the speed of a train approaching
speed restriction points; becoming alarmed about the speed,
he crossed to the right side of the cab and observed
that the equalizing reservoir gauge indicated a brake-pipe
reduction of only 11 or 12 pounds and the speed-recorder
indicated a speed of 61 miles per hour. He warned
the engineman that the speed was too great for Gulf Curve
and instructed him to make a further brake-pipe reduction.
The engineman did not answer but closed the throttle suddenly just as the engine entered
the critical point of the curve; he did not seem to be ill,
but rather in despair and mumbled something as though
he realized something was wrong. The engine did not seem to
hear heavily against the high rail; however, after the throttle
was closed he thought the rear end of the engine started
to leave the rail first and there was a jack-knife action
at the connection between the engine and tender as though some
added force caused the engine to become derailed and overturn.
He thought that a speed of 52 miles per hour was the highest
speed at which an engine could safely round Gulf Curve, but it
was his opinion that if the engineman had continued to work
steam in this instance the train could have rounded the curve.
He thought that closing the throttle caused a change
in force which resulted in the derailment. He said that it was
the custom of the engineman involved to apply the air brakes near
a point where a reduction in speed was required.
The road foreman of engines thought that if a heavy brake-pipe
reduction were made at signal 21531 or near it, a train
of 15 cars could be controlled properly around Gulf Curve.
Conductor Grattan stated that the air brakes were tested at Albany and were reported
as being operative, and they functioned properly en route.
He told the road foreman of engines and the
engineman that the train consisted of 15 cars. The engineman,
who was in his usual position in the engine cab, acknowledged
the information by a wave of his hand. Conductor Grattan
said that his train departed from Albany 21-1/2 minutes late.
There was no unusual incident between Albany and the
point of accident; the train was handled as smoothly as usual,
the speed was not excessive, and there was no time made up.
When the train was approaching the point of accident he was in
the fifth car and was not alarmed about the speed., as it was
about the same as on other trips. He thought that the brakes
were applied about 3 or 4 seconds before the accident occurred.
He estimated that the accident occurred at 11:33 or 11:34 p.m.
The weather was cloudy, but it was neither raining nor snowing.
Flagman Doran stated that the air brakes were tested before departure from Albany.
From the rear platform he inspected the train as it
rounded curves and last inspected it on a curve about 2 miles
east of the point of derailment; he did not observe any
dragging or defective equipment. As the train approached the
point of accident he was in the rear car. He thought the brakes
were applied about 1/2 mile east of the point of accident but
he did not observe any appreciable reduction in the speed of
the train. As his train was approaching Gulf Curve he went
out on the rear platform. He said that because of a run-in of
slack he was thrown through the end door into the coach.
He arose and was thrown down a second-time. He did not feel a
release of the brakes or an emergency application of the brakes.
Front Brakeman Sewak stated that when the train was approaching the
point of accident he was in the fifth car.
He felt a severe brake application about 1,500
feet east of the curve involved and thought that the speed
of his train we about 45 miles per hour at the time of derailment.
Baggageman Hill stated that he was in the second car as his train was
approaching the point of accident. He felt the brakes being
applied about 1,000 or 1,500 feet east of the curve involved.
He did not think that the brakes were applied in emergency.
Division Engineer Jones stated that he arrived at the scene of the accident
about 4 a.m., April 20, and examined the track thoroughly.
The first indication of damage was outside the high rail of
track No. 1, between the first and the second joints east of
the east abutment of bridge 456, and 37 feet west of the middle
of the curve. Starting at the east end of the second joint
which was the beginning of 'the disturbed track and proceeding
westward, the conditions were as follows: The inside spikes
on the low rail were raised increasingly 1/2 inch to 5 inches
from the first to the ninth tie, inclusive, and were pulled
out of the tenth, eleventh, and fifteenth ties the base of the
low rail was raised 1-1/2 inches at the ninth tie; the inside
spikes on the high rail were raised increasingly 1/2 inch to
2-1/2 inches from the sixth to the fourteenth ties, inclusive,
and on the fifteenth tie the spike was raised 1-1/2 inches;
the rail anchor was marked on the gage side and the gage rod dropped off the low rail but
was in place on the high rail; the sixteenth tie was shifted
1-1/2 inches northward. The first indication of derailment
was on the seventeenth tie; the top of this tie was gouged and
splintered outside the high rail and the spike on the inside
of the high rail was bent backward 90 degrees; the inside
spike of the low rail was pulled out. At the north end of the
eighteenth tie there was a mark 2-1/4 inches wide and 1 inch
deep the full width of the tie, and the rail anchor was bent.
On the nineteenth tie there was a flange mark 3/8 inch
deep and 1-1/2 inches wide the full width of the tie at a point
11.3/4 inches outside the base of the high rail; the tie was
chamfered at its extreme north end 2 inches wide and 1
inch deep the fun width of the tie. The gage rod between the
nineteenth and the twentieth ties was off both rails. On the
twentieth tie there was a flange mark 3/16 Inch deep and 1-1/2
inches wide the full width of the tie
at a point 12 inches outside the base of the high rail; the
tie was cut at its extreme north end and a piece was broken
off the west top edge extending from a point 8 inches outside
the high rail to the end of the tie; the inside spike of the
high rail was bent. On the twenty-first tie there was a flange
mark 1/8 inch deep and 3/4 inch wide the full width of the tie
at a point 12-1/2 inches outside the base of the high rail,
and a piece was broken out of the west edge of the tie
5 inches outside the base of the high rail; there was a bruise
2 inches wide on the west edge of the tie at a point 2 inches
inside the base of the low rail. The surface of the north
end of the twenty-second tie was splintered and there was a
mark on the east edge of the tie; there was a bruise on the
east edge of the tie 28 inches inside the base of the
low rail but the fiber of the wood was not broken. The surface
of the north end of the twenty-third tie was splintered
and there was a mark 3 inches deep on the west side; there was
a flange mark 31 inches inside the base of the low rail.
Between the twenty-third and the twenty-fourth
ties the rail anchor and the gage rod were disconnected.
The twenty-fourth, twenty-fifth, and twenty-sixth ties were
splintered over the surface on the outside of the high rail.
The twenty-seventh tie was splintered over the surface
and under the tieplate outside the high rail. Beyond the
twenty-seventh tie the track was torn up and it was necessary
to renew 75 ties. He said it was his opinion that the spikes
were pulled by some force which rolled the rails sufficiently
to draw the spikes partially; the spikes were drawn
by force and not by vibration. The marks on the ties indicated
a gradual tapering toward the outside of the track; he
did not observe any condition that could cause a change of direction.
Marks on the head of the high rail
west of joint No. 1 were too faint to establish their cause
conclusively. The last authorized work on track No. 1 was
performed during August 1939. He said that on April 16, 1940,
he observed the condition of the track at the point involved
from a train which passed over Gulf Curve at normal speed;
at that time the track was in excellent condition.
He said that based on an 84-inch center of gravity,
the equilibrium speed on track No. 1 was 39-1/2 miles
per hour, the safe speed was 45 miles per hour, and the
maximum safe speed was about 48 miles per hour; he did not know
the theoretical overturning speed. He thought the reason for
an absence of flange marks between the rails at the location
of the first marks of derailment was that the left wheels were
suspended. in the air. On April 20 and 21, he gaged the track
eastward from the second joint in the high rail east of bridge
456; the gage and superelevation were as follows:
The middle ordinate at joint No. 1 reflects shifting of track
during repair work after the accident.
He said that there was no evidence of tampering with the track.
Inspecting Engineer Bronson stated that he examined the damaged rails,
both at the scene of the
accident and again at vest Albany when they were realined
in their relative positions. On track No. 1 there were 6
rails on the outside of the curve and 4 rails on the inside of
the curve that were damaged; these rails were unbroken and they
remained coupled to the adjacent rails. Starting with the first
rail east of the initial mark of derailment and proceeding
westward on the outside of the curve, the result of
the inspection was as follows: The first rail was unmarked and
undamaged; as a result of a twisting motion imparted by
the third rail, the second rail was twisted outward throughout
a distance of 12 feet at the leaving end; there were marks
on the head of the second rail which were caused, undoubtedly,
by dragging of derailed equipment. There were numerous
marks on the gage side under the corner of the head of the
third rail which could not be identified with the path of any
derailed wheels. Starting about 6 feet from
the receiving end of the third rail, on the gage face there
was an irregular upward score followed by a downward mark
which then extended sharply upward; there was a distinct
score on the head of this rail which started at a point
12 feet west of the receiving end and extended diagonally
westward across the head of the rail a distance of 13 feet;
another mark almost paralleled this diagonal mark; it could
not be determined definitely that these marks were caused
by wheel flanges; there were marks in the web of the third
rail but their cause could not be determined; the spikes on
the gage side of the second and the third outside rails were
bent outward and the amount of bending and withdrawal of spikes
increased progressively westward; undoubtedly these conditions
were a result of the equipment following the derailed engine;
there were numerous marks on the fourth, fifth, and
sixth outside rails and on the first,
second, third., and fourth inside rails; however, these
marks were of less intensity than those on the second and
third outside rails; a line, starting at the third outside
rail on track No. 1, extending across a gap in track No. 3,
where there was a fractured rail on the inside and a twisted
rail on the outside of the curve, and extending to the rock
against which the engine stopped, indicated in a general
way the path of the engine after it became derailed. The
outside rails of track No. 1 were beaded over on the gage side
with a lip between 1/32 and 3/64 inch wide; the inside rail was
beaded over similarly on the gage side. Inspection of the track
throughout a distance of 1 mile immediately east of the point
of accident did not disclose any condition that might have
contributed to the cause of the accident. The ties were spaced
regularly and were in good condition. The gage, line and surface
were uniform. There was no indication of dragging equipment.
Section Foreman Quinto stated that he had been in charge of the section
involved for 29 years. On. April 18 he inspected track No. 1 on
Gulf Curve for surface and alinement, and also gaged the
cross-levels; the condition of the track was satisfactory
at that time. One of his men who inspected the track
on April 19 did not report any unsatisfactory condition.
He had experienced no difficulty in maintaining the desired
superelevation on the curve involved. He said that on April 18
he observed trains as they rounded the curve; at that time
there was nothing unusual- in their movement. He had never
observed trains exceeding the speed limit on Gulf Curve.
The last work performed on this curve was in August, 1939.
Master Mechanic Fahey stated that be arrived at the scene of the
accident about 4:05 a.m., April 20, and examined engine 5315.
The throttle was unlatched and open 10 notches but the
lever and the quadrant were bent and the throttle extension
rod was broken at the location of the front-end throttle.
Immediately ahead of the door sheet there was a jagged tear in
the wrapper sheets the metal of which appeared to be of full
thickness and bore no evidence of having been overheated.
The crown-sheet metal was of full thickness and disclosed no
evidence of having been overheated. He thought the explosion
was a result of a rock puncturing the wrapper sheet,
as the hole was the shape of the rock that had pierced it.
The engine frame on both sides back of the
first pair of driving wheels and at the tailpiece was broken.
He thought the frame was broken as a result of either
the explosion or the impact of the engine against the rock.
The engine frame swung around until the third pair of driving
wheels was ahead of the first pair and against
the back cylinder-heads. After the engine was moved to West
Albany Shops he gaged the wheels; the results were as follows:
Spacing back-to-back in four positions:
Note:- The 4-wheel trailer truck was not found and it is supposed that it fell in the river.
Diameters of engine-truck wheels and driving-wheel tires were as follows:
He said that the No. 1 pair of driving wheels was placed in a
wheel lathe and the axle and the wheel hubs
ran true; however, the right wheel-center vas dished inward
1/4 inch at the counter-balance location; in his opinion
this wheel became dished as a result of striking the rock
against which the engine stopped. He said that the lateral
of all driving wheels-was 3/8 inch. The engine-truck axles
were equipped with roller-bearing boxes; 1/8 inch play was
maintained in the pedestal jaws. The capacity of the tender of
engine 5315 was 28 tons of coal and 14,000 gallons of water.
He estimated that 21-1/2 tons of coal and about 11,000
gallons of water were in the tender at the time of derailment.
Assistant Master Mechanic Pease stated that on April 22 he removed the speed recorder
from engine 5315. The independent brake-valve handle
was broken, the rotary valve was in quick-application
position, the automatic brake-valve handle was in
emergency position, and the double-heading cock was closed.
He said that he attached no significance to the position of
the brake valve or of the double-heading cock as they were so
located that they might have been disturbed by debris or by
persons removing bodies of employees. He examined the radial
buffer between the engine and the tender and found that it
was in good condition. The coupler and the angle cock at the
rear of the tender were broken off. A section of the ashpan,
weighing 66-1/2 pounds, and several grate units were found on
the south bank of the river 620 feet distant from the engine.
Assistant Superintendent of Equipment Parsons stated that he examined the engine-truck
springs, hangers and equalizers, and the driving-box
springs, hangers and equalizers, and there were no defects.
General Foreman of Car Department Ruxton stated that he arrived at the point of
derailment about 12:55 a.m., April 20.
He found nothing wrong with any of the equipment
which might have been a contributing cause to the accident.
He examined all couplers, four of which were of the
tight-lock type, and found no detects that appeared to have
existed prior to the derailment. There were slight brake burns
and skid marks on the treads and flanges of all wheels. These
brake burns and skid marks were progressively heavier from
the front to the rear of the train. He Stated that there was
no evidence of buckling or telescoping on any of the cars.
Supervisor of Boilers Usherwood stated that he arrived at the scene of the
accident at 11:40 a.m., April 20, and examined engine 5315.
There was no indication of overheating of the
firebox sheets, nor any defect which might have contributed
to the failure of the firebox. Portions of the crown
sheet and of the right side-sheet were folded downward over
the flue sheet; the remainder of the crown sheet and of
the right side-sheet were folded downward over the door sheet.
There was discoloration of the crown-sheet metal
between the seventh and ninth longitudinal rows of staybolts
to the right of the center-line and from the third to
the ninth transverse rows of staybolts back of the flue sheet;
however, this discoloration was caused by arch brick
being wedged between the flue sheet and the crown sheet when
the latter was forced downward against the flue sheet. After
]the engine was removed to West Albany Shops he examined the
firebox in detail; the results were as follows: The wrapper
sheet was punctured inward, the area of the puncture being 672
square inches; one side of this hole, which was to the right
of the center-line of the firebox and triangular in shape,
extended along the sixth longitudinal row of staybolts
from the back-head to the ninth transverse row of staybolts,
the second edge extended along the back-head between
the sixth and ninth longitudinal rows of staybolts, and the
third edge followed a diagonal course)
