26F Quick Release |
Allows the actuating release of an automatic brake application of the locomotive brake cylinders in response to actuating operation of the independent brake valve or the dynamic brake interlock magnet valve. |
|
P2A Brake Application Valve |
Allows a safe penalty brake pipe reduction in response to: - Safety Control foot pedal - Crew alerter - Cab signal penalty - Positive Train Control penalty |
|
SA26 Independent Brake Valve |
Develops signal pressures to control the application and release of the locomotive brake cylinders independent of the automatic brake system. |
|
26F Control Valve |
Develops signal pressures to control the application and release locomotive brake cylinders automatically in response to the brake pipe pressure. |
|
26C Automatic Brake Valve |
Develops, controls, and pressure maintains brake pipe pressure in reference to equalizing reservoir volume. |
|
H-5 Type Relay Air Valve |
Serves as an air relay in which a signal pressure pilots a set of normally open or normally closed passages for the control of air flowing to various components. This valve is regularly used for PCS time delay and for actuating 30A-CDW equipment. |
|
C-140 Dead Engine Feature |
Allows for main reservoir charging from brake pipe air pressure on a locomotive moving dead-in-train. |
|
SA26 Independent Brake Valve |
Develops signal pressures to control the application and release of the locomotive brake cylinders independent of the automatic brake system. |
|
J Type Brake Cylinder Relay |
Operates in response to an air signal to allow main reservoir pressure to flow to the brake cylinders in proportion to the controlling signal. Signal sources are the SA26 independent and the 26F Service Control valve. |
|
A-1 Charging Cutoff Pilot Valve |
Operates in response to an emergency brake pipe reduction. Sends a signal to: - Cut-off brake pipe charging at the 26C Automatic Brake Valve - Allow timed emergency sand operations - Cut off loading of the locomotive through the PCS |
|
#8 Vent Valve |
Responds to a rapid reduction in brake pipe pressure to further vent the brake pipe locally to assist in the propagation of an emergency application. |
