This section now refers to the Engine Blueprint and not the previous Engine Simulation Blueprint
The following Brake Control Positions are available. They should be used as ‘Notches’ on a Notched Lever TrainBrakeControl or EngineBrakeControl.
The following table describes the fields inserted into the Notched Data Identifiers. Values in these fields are a decimal fraction of the full action of the notch (1).
Direct |
Just 0-1 full release to full application |
MaxQuickRelease |
Air Brakes only, release at Max Quick Release Rate parameter |
SelfLapped |
The train pipe maintained at current pressure |
Hold / HoldLapped |
Isolates the controller from the train pipe |
NeutralHandleOff |
Isolates the controller from the train pipe |
MinimalReduction |
Pressure is set to system pressure minus Minimum Reduction Pressure |
FullService |
Pressure is set to Max Pressure minus Full Serice Pressure Drop |
Suppression |
Pressure set to Max Pressure - Minimum Reduction Pressure |
Emergency |
Full on Application. Control Value is set to 1.0 |
GraduatedQuickRelease |
Air Only - release rate is proportional to 'Max Quick Release Rate' and the Control position |
Release or ReleaseLapped |
The release rate is proportional to 'Max Release Rate' and the Control position |
EPApply or EPHold |
Electro Pneumatic Brakes only. Apply / Hold the EP Brake |
Running |
The controller closes all variable methods of train pipe control off |
Note that a device maintained on idle will still operate (such as a small ejector, compressor or exhauster). On Vacuum brakes, you should get a slow release in 'Running' but only if there is a source working to restore the pressure |
GraduatedSelfLap |
The Train Pipe is maintained at pressure proportional to Control position |
Apply |
The Application rate is proportional to Control position |
ContinuousService |
The Application rate is proportional to Control position & Max Application Rate + Min Continuous Service Release Rate |
GraduatedSelfLapLimited |
This is the same as GraduatedSelfLap but proportional to Full Service Pressure Drop |
GraduatedSelfLapLimitedHolding |
The Train Pipe Pressure is proportional to Control position and the difference between Full Service Pressure Drop and Minimum Reduction Pressure |
GraduatedSelfLapLimitedKeepPressure |
The Train Pipe Pressure is proportional to Control position and the difference between Full Service Pressure Drop and Minimum Reduction Pressure |
