Bug Description

In The Route Europa2 Innsbruck-St.Anton, activity Bride and groom, the Train is initialised with triple-valve in emergency-position. If I release the brake the triple-valve doesn’t switch to release and the train can never be moved.
The initialisation of the AuxRes is wrong if the brakes are initialised fully applied.
With a Pressure of 50psi in the Brakezylinder (brake fully applied), the AuxRes can’t have a pressure of 70psi (which is the max. pressure of the brakesystem) in singlepipe-brakes.
I found in the MSTS-Original 380.eng-file the following error:
TrainBrakesControllerMaxSystemPressure( 70 )
TripleValveRatio( 2.5 )
BrakeCylinderPressureForMaxBrakeBrakeForce( 70 )
The Pressure in the brake cylinder can in this case never go higher then 50psi.
70psi *(3.5)/(2.5)= 50psi
After the initialisation brakecylinder-pressures are higher then 50psi.
(During the Simulation the pressure in the brakezylinder are shown correct.)

The error in the .eng file is now corrected by OR if the experimental option "Correct questionable braking parameters" is checked.
