Controls and Indicators
52. Train Air Brake Control
A variable air pressure valve. The “RELEASE”position enables
compressed air flow to release the Train Railcar Brakes. The “APPLY”
position releases air pressure from the Train Railcar Brakes causing the
brakes to engage. This valve may be positioned anywhere between
full release to full applied to provide braking power for the rail car
consist when operating. The amount of braking action provided by the
Train Air Brake Control may be measured by the white hand on the
Rail Air Reservoir/Rail Air Brake Gauge (item 37).
53. Train Brake Emergency Valve
A red “push/Pull” knob. Pull the knob out to charge or open compressed
air flow to the Train Air Brake Control (item 52). Push the knob
in to release air pressure in the Train Railcar Brake system.
Note:
The Train Brake Emergency Valve (item 53) operates in conjunction
with the Train Rail Brake Control (item 52) and must be in the up
position in order to allow the Train Air Brake Control to charge the
Train Railcar Brakes with air to release the brakes.
Note:
Railroads operate their cars at brake pressures of approximately 90 PSI.
54. Front Rail Pressure Control
A variable pressure rotary control knob with locking collar. To change
the hydraulic pressure being applied to the rail wheels, loosen the locking
collar and turn the control knob; clockwise to increase pressure or
counterclockwise to decrease pressure. The pressure being applied to
the rail unit will be displayed on Front Rail Pressure Gauge (item 32).
54. Rear Rail Pressure Control
Identical purpose and function to the Front Rail Pressure Control
(item 54 above), but servicing the rear rail unit. It’s pressure is displayed
on (item 33).
