Thank you for verbose analysis.
As we have special "blocking" valve with detachable handle (for safely change cabs with all of brake controls set at proper state), the driver valve's handle is continuously fixed on its shaft by the nut, so the NeutralHandeRelease notch for it is inactual.
You can see its absence at the bottom, and the "Normal BP pressure adjusting nut" at the center of image.

Detachable handle is at its place and turned on (downwards) - see at the left.

Many thanks for the translation.
It looks as though we have already got as close as possible to that controller in OR at the moment.

The only work around that I can see for the moment is that you use two different eng files for passenger and freight braking.


The eng file for passenger braking would use:

TrainBrakesControllerMaxApplicationRate( 1.0bar/s ) Comment ( 5.0 to 4.0 kgf/cm2 in 4-5 seconds in position V )

and the eng file for freight train braking would use:

TrainBrakesControllerMaxApplicationRate( 0.25bar/s )  Comment ( 5.0 to 4.5 kgf/cm2 in 15-20 seconds in position VA )

This is what I do for British locos at the moment - they have a separate Goods / Passenger switch that gives a slower rate of braking for goods trains. Although with air brakes in UK we seem to do this not by changing the application rate of the air train pipe but by slowing down the operation of the locomotive brake cylinders with a reducing valve.

For both passenger and goods the eng section has the same rate for the train pipe:

TrainBrakesControllerMaxApplicationRate( 4.2psi/s )

The wag section of the eng file for passenger operation has

MaxReleaseRate ( 9.0psi/s )  Comment ( * Locomotive brake cylinder 68 to 5 psi in 7.8s air passenger mode * )
MaxApplicationRate ( 20.0psi/s ) Comment ( * Locomotive brake cylinder 0 to 70 psi in 3.5s in air passenger mode * )

and the wag section of the eng file for goods operation has

MaxReleaseRate ( 2.4psi/s )  Comment ( * Locomotive brake cylinder 68 to 5 psi in 29.6s air goods mode * )
MaxApplicationRate ( 3.4psi/s ) Comment ( * Locomotive brake cylinder 0 to 70 psi in 21.0s in air goods mode * )

1. As IV-th position, I have to use "SelfLapStart 0" for not to confuse anybody with "Running" appeared on HUD, instead of "Lap"
2. After IV, the VA follows, then V and VI.
3. So, the MinimalReductionStart doesn't mean minimal discharge rate (actually it has no effect at all, being placed as a token for VA)
4. For not to change *.cvf-files, I left first digits(position of each notch) as they were originally.
5. You have shown to me the possibility of conjunction an EP and a regular brake's notches in one lever's description, so why can't we assign something like EPApplyStart as a token for VЭ position of the 395 passenger locomotive driver's valve? But we need to do it correct, as simply insertion of it gives max BC pressure only 2,5 bar instead of 3,8 as the first digit is 0,4 and, as I understood You, the EP effect is sensitive to that...

So, as a result I would like to make a list of missing brake functions for asking ORTS programmers to add them, and a list of inaccurate/incomplete described features to use it for ORTS Manual's correction.

[Weter]

I have found more successful descriptions of 395 functioning too, and going to choose the best.

I have added some suggestions to the Open Rails Road Map on Trello - you may wish to add further suggestions.

Now, it's time for me to run ORTS and test all variants You offered to me.
This could clear some things or produce some further questions.

The last thing I would to concentrate an attention on and to ask:
Is it possible to have a single notch that works like Full service <the final BC pressure depends on the time, during wich, the handle was held at that position before returning to Hold>, but applies EP brakes (without BP discharge, at fast rate of application and with gradual release)?

[darwins]

The answer to that one is yes.

Notch ( 0.2  0 TrainBrakesControllerEPFullServiceStart )

[Weter]

Wow! I knew only EPapplyStart before.
Thanks for hint!
So, this variant may look like follow:

Brake_Train ( 0 1 0.1 0.2
 NumNotches ( 7
  Notch ( 0    0 TrainBrakesControllerFullQuickReleaseStart ) Comment ( I RELEASE and OVERCHARGE ) Comment ( Overcharge not currently possible in OR )
  Notch ( 0.1  0 TrainBrakesControllerReleaseStart ) Comment ( II RUNNING )
  Notch ( 0.2  0 TrainBrakesControllerHoldLappedStart ) Comment ( III LAP - without feed )
  Notch ( 0.3  0 TrainBrakesControllerSelfLapStart ) Comment ( IV LAP - with feed )
  Notch ( 0.4  0 TrainBrakesControllerEPFullServiceStart )  Comment ( VЭ EP-Apply for cars: fast and without BP discharge)
  Notch ( 0.5  0 TrainBrakesControllerFullServiceStart ) Comment ( V APPLY )
  Notch ( 0.9  0 TrainBrakesControllerEmergencyStart )
 )
)

Wich brake equipment types should be mentioned in engine section so far?

Wich brake equipment types should be mentioned in engine section so far?

for what you have so far the

	BrakesTrainBrakeType( "Air_twin_pipe" )
	BrakesEngineControllers( "Train" )

will cover it - use single rather than twin if appropriate....

[Weter]

And what about EP?
Both, the passenger locos and EMUs/DMUs commuter trains, that use 395 valves has EP braking as main, but able to apply pneumatic as a backup. And the locomotives themself don't have EP air distributors (they have ones, similar as freight cars do), so their own brake system (wagon part of the *eng-file) is not EP. They certainly have engine(independent) brake as well.
