ARA Transportation
Technology Center
* TEST OBJECTIVE
Determine lbs. of
pulling pressure needed
to overcome chock
resistance.
* TEST PROCESS
Winch cable attached to
130 ton loaded hopper
car. Brakes not applied.
* RESULT Chocks
withstand 25,000+ lbs.
of drawbar pull - equal
to 32% of a locomotive
drawbar pull.

Replaceable spurs bite into
the rail to keep the chock
from sliding.

When spurs become dull
from use, turn to a new sharp
edge. After 3 turns, replace
the spur, not the chock!

Texas shortline
* TRACK 1.5° downhill
slope, 10° curve.
* LOAD 6-axle
locomotive, engine
idling, coupled to 100ton hopper car.
Gross weight
633,300 lbs.
* RESULT All brakes
released: no sliding,
chock held wheel in
place. Engineer had to
rev up to 3/8 full power
to ride over chock.
