London - Port Stanley Braking Problem

[woodfyr]

The LPS (mini route) is one of the few that I can run in OR or MSTS. In OR the LPS motorcars #s 1-14 will not respond to braking. (see attached). When brakes are applied the pressure drops but nothing happens on the brake cylinders.

All work fine in MSTS.

These units have "Distributor" , "Air twin pipe" systems. Have tried fiddling (but do not know what I'm doing) in the .eng file with no luck. I hope this is not one of those "Duh ??" moments.

Any thoughts or suggestions ?Open Rails 2017-11-05 01-35-43.jpg

The screenshot isn't much help as the very small resolution makes it unreadable.

Left is MSTS. Right is OR.

The problem is caused by the way the braking parameters are set up. They are taking advantage of an MSTS quirk that does not exist in OR. Open Rails only uses proper data, no fudges.

You will find that ALL MSTS powered units are underpowered in OR because MSTS files were set up to use the power at the rail figure whereas OR uses the power figure before all resistances are removed from the total. 3000hp is exactly that, not 2240 or whatever MSTS used. Now to these brakes

First of all we have MaxBrakeForce ( 0.3414kN ) in the wagon section brake parameters which will do diddly squat in stopping anything in OR. Second problem related to the first is BrakeCylinderPressureForMaxBrakeBrakeForce ( 0.50 ) which is why it does not register on the gauge in OR, that is only half of one PSI.

You will get working brakes if you change MaxBrakeForce to 25kN and BrakeCylinderPressureForMaxBrakeBrakeForce to 60 or 70

Baldwin,

Thank you for that. I had a feeling that was the situation. I am slowly getting into the inner sanctum of MSTS vs OR physics as applied.

Now that we have a WIP AE by Goku things should get Much better.

I owe you a pint.
