Here's an example using Darwin's controller:

ORTSTrainDynamicBlendingTable(
    0 (0 0 300km/h 0)
    0.2 (0 0 300km/h 0)
    0.3 (0 0.4 300km/h 0.4)
    0.4 (0 0.7 300km/h 0.7)
    0.5 (0 1 300km/h 1)
    0.8 (0 1 300km/h 1)
    1 (0 0 300km/h 0)
)

Brake_Train ( 0 1 0.1 0.2
NumNotches ( 8
Notch ( 0       0 TrainBrakesControllerReleaseStart )  Comment ( Release / Running )
Notch ( 0.2  0 TrainBrakesControllerEPHoldStart )  Comment ( Hold EP )
Notch ( 0.3  0 TrainBrakesControllerEPHoldStart )  Comment ( Regeneration I )
Notch ( 0.4  0 TrainBrakesControllerEPFullServiceStart  )  Comment ( Regeneration II and EP )
Notch ( 0.5  0 TrainBrakesControllerEPFullServiceStart ) Comment ( Regeneration III and EP )
Notch ( 0.6  0 TrainBrakesControllerHoldStart ) Comment ( Lap Air )
Notch ( 0.8  0 TrainBrakesControllerFullServiceStart ) Comment ( Apply Air )
Notch ( 1.0  0 TrainBrakesControllerEmergencyStart ) Comment ( Emergency ) ) )

Probably this is a good moment to allow custom labels for Notches. This would be useful both for notched throttle and brake controllers. The only problem I see is with i8n, but we have already broken that with ORTSLabel, so I think we can do it here too.

Hello.

It is interesting to see both the traction curve and the dynamic brake curve together. That gives a good clue to guessing the braking curves for locomotives that we can not find published curves for.

Yes please. http://www.elvastower.com/forums/public/style_emoticons/default/clapping.gif

How about something like this?

Brake_Train ( 0 1 0.1 0.2
NumNotches ( 8
Notch ( 0       0 TrainBrakesControllerReleaseStart ORTSLabel ( "Running" ) )
Notch ( 0.2  0 TrainBrakesControllerEPHoldStart  ORTSLabel ( "Hold EP" ) )
Notch ( 0.3  0 TrainBrakesControllerEPHoldStart ORTSLabel ( "Regeneration I" ) )
Notch ( 0.4  0 TrainBrakesControllerEPFullServiceStart ORTSLabel ( "Reg. II EP" ) )
Notch ( 0.5  0 TrainBrakesControllerEPFullServiceStart ORTSLabel ( "Reg. III EP" ) )
Notch ( 0.6  0 TrainBrakesControllerHoldStart )
Notch ( 0.8  0 TrainBrakesControllerFullServiceStart )
Notch ( 1.0  0 TrainBrakesControllerEmergencyStart ) ) )

Looks good. So many brake controllers that would be useful for. Also some throttles and some gear changes and maybe some other controls.

[pschlik]

Custom labels would be a great thing to have. It's all too easy to find situations where the default notch text isn't what you need.

Another cool feature would be a delay between the controller and the brake effort, since the brake reacts in realtime what is unreal.
Something similar to the RateOfChangeUpRPMpSS and RateOfChangeDownRPMpSS would be great to simulate this behavior.

Thanks. It seems this is working for train brakes like this:

Brake_Train ( 0 1 0.01 0.50
NumNotches ( 5
 Notch ( 0.0 0 TrainBrakesControllerOverchargeStart ORTSLabel ( "RELEASE" ) )
 Notch ( 0.2 0 TrainBrakesControllerReleaseStart ORTSLabel ( "RUNNING" ) )
 Notch ( 0.5 0 TrainBrakesControllerHoldLappedStart  ORTSLabel ( "LAP" ) )
 Notch ( 0.7 0 TrainBrakesControllerFullServiceStart ORTSLabel ( "APPLY" ) )
 Notch ( 1.0 0 TrainBrakesControllerEmergencyStart ORTSLabel ("EMERGENCY") ) ) )

but not for independent brakes like this:

 Brake_Engine ( 0 1 0.1 0
NumNotches ( 4
 Notch ( 0.0   0 EngineBrakesControllerReleaseStart ORTSLabel ( "RUNNING" )
 Notch ( 0.3   0 EngineBrakesControllerHoldLappedStart ORTSLabel ( "LAP" )
 Notch ( 0.7  0 EngineBrakesControllerApplyStart ) ORTSLabel ( "SLOW APPLICATION" )
 Notch ( 1.0  0 EngineBrakesControllerEmergencyStart ) ORTSLabel ( "QUICK APPLICATION" ) ) ) )
