ORTS EP Brakesystem (Problems)
==============================

In my trainset i prefer to handle the real cylinderpressure value’s of each locomotive/train class.

Some trains have a (special) way of EP:
• Brakepipe stay on 5 BAR (TrainBrakesControllerMaxSystemPressure).
• Only go to 0 BAR when there is emergencybrake (TrainBrakesControllerFullServicePressureDrop 0 ).
• ORTS handle this but with strange bugs => aux reservoir (air go to very high value’s, in real this reservoir blow ups with this pressurevalue’s).

Max pressureDrop on locomotives & passenger wagons:

* On some locomotives i must handle TrainBrakesControllerFullServicePressureDrop ( 2.0bar )
This works good for trains with PBL trainbrakelevers (impulse), but it gives this problem:

Wagons dont release brakecylinders. Only when you do emergencybrake and fill brakepipe back to 5 BAR they release.




Reason why TrainBrakesControllerFullServicePressureDrop ( 2.0bar ) is used is that PBL trainbrakelever trains after release emergencybrakes bring the brakepipe to 3 BAR.


Driver must be confirm further release on normal way.

On ENG file i must use “BrakeSystemType ( "Air_Twin_Pipe" )” For have blending. With “EP” there is not blending . Normal it must be otherwise

So for moment 2 Pipe trains give blended brake with emergency, in real this is not in my country.
Locomotives that have “EP” have no blended brake with emergency now, in real there is blended with emergencyrbrake.

Only when i use a brakecontroller script (Serana), there is blended braking.

Hello,

Little update:

If i do test on al engines and wagons with:

BrakeEquipmentType ( "Distributor,auxilary_reservoir, Handbrake" )
BrakeSystemType ( "Air_Twin_Pipe" )


There is no problem, but indeed no EP no more.

That can not be the intention.
