26L Brake Valve Positions Release |
Used to charge Brake Pipe (BP) Pressure, resulting in the release of the train/engine brakes. |
|
|
26L Brake Valve Positions Minimum Reduction |
Approx. 5-7 lbs BP reduction. (Minimal Brake cylinder pressure build-up) |
|
|
26L Brake valve Positions Full Service |
Approx. 23-26 lb. reduction in Brake Pipe resulting in 40-45lbs of Brake Cylinder pressure. |
|
|
26L Brake Valve Positions Suppression |
Used to recover from a Penalty Brake application by restoring Application Air. |
|
|
26L Brake Valve Positions Handle Off |
Used when changing operating stations. Also used after an emergency brake application to determine if the train is ready to be charged. |
|
|
26L Brake Valve Positions Emergency |
A raid reduction in BP Pressure, resulting in an excessive buildup of BC pressure (approx. 70-90 psi) |
|
|
Automatic Brake Valve Cut-Out Cock (ABVCOC) Pass |
Used in Passenger service. This option allows for the graduated release of the train brakes. NOTE: The use of this position while operating freight type equipment will result in an undesired release of the train brakes whenever the ABVH is moved toward the Release position. |
|
|
Automatic Brake Valve Cut-Out Cock (ABVCOC) FRT |
Direct release of the train brakes (non-graduated) |
|
|
Automatic Brake Valve Cut-Out Cock (ABVCOC) OUT |
Used to cut out the 26L Brake Valve, checking for BP charging & when testing for BP leakage. |
|
|
Independent Brake Valve (IBV) Fully Applied |
Applies 40-45 lbs. of pressure to the brake cylinders. |
|
|
Independent Brake Valve (IBV) Fully Released |
Releases the brakes on the engine or engines only. |
|
|
Independent Brake Valve (IBV) Actuating/Bail OFF/ Quick Release |
Depressing the IBVH will result in the release of BC pressure on the locomotive consist only and has no effect on the cars of a consist. |
|
|
MU-2 Valve Lead Cut In |
Enables an Independent Brake (IB) application from the control stand |
|
|
MU-2 Valve Trail Cut Out |
To be paced in the cut out position when changing control stands on an MU'd locomotive consist. NOTE: As a result, when placed in the Trail-Cut-Out position, the independent Brake Valve will NOT develop brake Cylinder pressure on the locomotive from that location |
|
|
Throttle Positions MU Throttle Stop |
Used to shut down diesel engine or engines when the locomotives are coupled in multiple. |
|
|
Throttle Positions Idle |
The throttle must be in this position to enable the use of the reverser handle. |
|
|
Throttle Positions Run 1 Thru RUN 8 |
Each position determines a preset RPM on the diesel engine. |
|
|
SA 26 Automatic Brake Valve Handle Positions: Release |
This position is used for charging the equalizing reservoir and brake system. The brake valve is carried in this position when the brakes are released. |
|
|
SA 26 Automatic Brake Valve Handle Positions: Hold |
This position holds brake cylinder pressure while recharging brake pipe pressure. This position is also used after obtaining brake assurance. |
|
|
SA 26 Automatic Brake Valve Handle Positions: Lap |
This position is used to hold a service brake application applied. It is also used to reset the locomotive brake equipment following a penalty application. |
|
|
SA 26 Automatic Brake Valve Handle Positions: Service |
This position is used to reduce equalizing reservoir pressure. When the equalizing reservoir is reduced in the service position, brake pipe pressure will also reduce an equivalent amount. This activity will start when the brake valve is placed in the service position and will continue to function in the Lap position until brake pipe pressure has been reduced to equalizing reservoir pressure. |
|
|
SA 26 Automatic Brake Valve Handle Positions: Handle Off |
This position is used when a locomotive is a trailing unit or hauled dead in a train. |
|
|
SA 26 Automatic Brake Valve Handle Positions: Emergency |
This position provides an emergency brake application. This position is always available. This position is also used to reset the locomotive brake equipment following an emergency brake application. |
