CSX Conductor Training Part 3: Air
Brake & Train Handling Rules
Who are responsible for the condition of air brake and air signal equipment on
locomotives and cars to the extent it is possible to detect defective equipment by the
required air brake test? - ✔️✔️Trainmen
Brake cylinder release valve - ✔️✔️Valve designed to provide a means for releasing
brake cylinder pressure on a freight car by actuating a bleed rod near the control valve
that is to be identified by a small loop or handle on the bleed rod.
Angle cock - ✔️✔️A valve located at each end of a locomotive or car used to open or
close the brake pipe. Handle in line means it's open. Handle crosswise means it's
closed.
Brake cylinder - ✔️✔️A device on cars and locomotives, which converts the force of
compressed air into a mechanical force to move brake shoes against the wheels.
Contains a piston and piston rod. Piston out mean brakes are applied. Piston released
inside means they are released
Brake pipe - ✔️✔️The pipe extending the length of the car, locomotive or train through
which air brakes are charged, applied and released.
Branch pipe cut out cock - ✔️✔️Device used for cutting in and cutting out the control
valve on a locomotive or car. Handle crosswise with pipe, the cut out cock is open.
Handle in line with pipe, the cut out cock is closed.
Control valve - ✔️✔️Device on locomotives in cars that charges, applies and releases
breaks in response to changes in brake pipe pressure.
Auxiliary reservoir - ✔️✔️A storage volume for compressed air, charged from the brake
pipe, which provides air pressure for use in service and emergency brake applications.
Emergency reservoir - ✔️✔️A storage volume for compressed air, charged from the
brake pipe, which provides air pressure for use in emergency brake application and
certain recharge features.
Reduction relay valve - ✔️✔️A device found on freight cars when the length of the
brake pipe is 75 feet or longer. Primary function of the A-1 reduction relay valve is to
assist the control valve with the venting of brake pipe air during train air brake
application.
, No. 8 Vent Valve - ✔️✔️Will malfunction and cause a continuous exhaust of brake pipe
air that prevents the brakes from releasing.
Safety appliance - ✔️✔️Stationary hand holds, ladder rungs, cross over platforms and
stirrups designed for climbing, riding or getting on or off equipment.
The air brake on a car must be considered inoperative when it has a brake cylinder
piston travel in excess of: - ✔️✔️10.5 inches
What percentage of operative air brakes must each train at least have when in route? -
✔️✔️85%
While enroute each train must have an operative air brake on the: - ✔️✔️Rear car
When calculating the number of operative air brakes count: - ✔️✔️Locomotives as a
car
Control valve on articulated equipment as a car
What is the correct air brake pipe pressure for road freight trains? - ✔️✔️90 PSI
What department must the conductor accept results of any inspection -
✔️✔️Mechanical department
Who is equally responsible for ensuring cars and locomotives receive the required
inspections and brake tests? - ✔️✔️Each crewmember
When making air brake tests using telemetry, how do you determine that the brakes at
the rear end of the train have applied and released? - ✔️✔️A 5-PSI brake pipe
reduction indicates applied.
A 5-PSI brake pipe increase after an application is made indicates release.
After an air brake test, verify that brake pipe pressure is being restored at: - ✔️✔️The
rear of the train before proceeding.
Name the two different methods for testing brake pipe leakage - ✔️✔️Air flow methods
or brake pipe leakage method
After making a 20 pound brake pipe reduction, brake pipe leakage must not exceed -
✔️✔️5-PSI per minute or 60-CFM per minute
If brake pipe leakage exceeds 5 psi per minute, the brakes are: - ✔️✔️Inoperative
