Although it needs updating, the information here still pretty much works
"A Guide to Vacuum Brakes in Open Rails"
Apart from the guidance you mention at
Coals to Newcastle website. The site also has example Open Rails files that you can download for the
Modified Hall class.
The text file that you have uploaded is basically an MSTS eng file. If you want to get the best performance out of OR, it is worth creating OR eng files which make good use of all the additional features that are available in OR. As mentioned above Coals to Newcastle already has a file for a Modified Hall - so you can just substitute in your file names and shape names. If you wanted to use that as a basis for making an OR file for a Castle or a Mogul or something else I would be happy to assist or look over the file for you.
Some point from what you have.
BrakeCylinderPressureForMaxBrakeBrakeForce( 25 ) should include units BrakeCylinderPressureForMaxBrakeBrakeForce(
25inHg )
TrainBrakesControllerMaxSystemPressure( 25 ) should similarly read TrainBrakesControllerMaxSystemPressure(
25inHg )
For the controls the MSTS version:
Brake_Train ( 0 0.99 0.1 0.98
NumNotches( 2
Notch(0.0 0 TrainBrakesControllerRunningStart )
Notch(0.05 1 TrainBrakesControllerApplyStart )
)
)
...was written to work with an attempt in MSTS to model the large ejector separately - which is true to GWR practice but not supported in Open Rails.
Hence in the Open Rails version becomes either:
Brake_Train ( 0 1 0.3 0.4
NumNotches( 3
Notch(0 0 TrainBrakesControllerReleaseStart )
Notch(0.3 0 TrainBrakesControllerRunningStart )
Notch(0.6 0 TrainBrakesControllerApplyStart )))
or
Brake_Train ( 0 1 0.3 0.4
NumNotches( 4
Notch(0 0 TrainBrakesControllerReleaseStart )
Notch(0.3 0 TrainBrakesControllerRunningStart )
Notch(0.6 0 TrainBrakesControllerApplyStart )
Notch(0.9 0 TrainBrakesControllerEmergencyStart )))
...here "Release" needs to be added as OR does not support a separate large ejector. "Emergency" is added if you also want to have a faster application as in Open Rails the vacuum brake valve is only either on or off and not graduated.
For the small ejector control use:
ORTSSmallEjector ( 0 1 0.1 0.5 ) to replace SmallEjectorOrCompressor( 0 1 0 )
On the GWR Kings, Castles and Halls were fitted with Large Ejector, Small Ejector and Vacuum Pump.
Most GWR locos had only Large Ejector and Vacuum Pump.
