Bug Description
When you close the throttle on a steam locomotive in ORTS the exhaust continues as though it were open and pulling. I have discussed this issue on the ET forum but it is time to memorialize it with a bug report.
Steam locomotives DO NOT chuff with the throttle closed and coasting. MSTS properly stops chuffing when the throttle is closed but OR does not. Some folks have found a workaround by altering a locomotives .sms file, but this is a compatibility issue with MSTS and the users shouldn't have to restructure every .sms file in their Trainset folder to work around an OR glitch.

Locomotive chuffing volume is controlled by the following formula, it is proportional to the effort the engine puts up at a time:
Variable2 = Math.Min( CylinderPressur ePSI / MaxBoilerPressu rePSI * 100f, 100f);
This variable is closely related to the actual steam locomotive physics calculations. In MSTS the steam physics is completely different, and probably partly broken. Thus replicating the behavior here is nearly impossible. This was discussed on ET, and based on the discussion I would mark this bug report as "Won't fix" status.
