You must expect to see results like this in experimental code changes but that's no reason to revert! http://www.elvastower.com/forums/public/style_emoticons/default/goodnight.gif
I see wonderful progress here. Brandon, just keep posting the meaningful feedback with data to backup your observations.
This is how OR is becoming a world class train sim, by testing by you and others; A very good thing I'd say!
Microsoft didn't let you do much of that, did they? With OR, you are shaping the Sim. Good work!
best regards,
vince

There are several factors that will affect how much fuel is used. Incorrect eng/wag file data, specially the Davis resistance figures. Getting those wrong will dramatically affect fuel and water usage.
Heavy handed use of the reverser will also drive up fuel and water usage, although I see that you are not using any water. That in itself suggests that there might well be errors in the eng file. Could you also post the eng file you are using so it can be checked for possible errors.

Have you tried the Niagara found on the CTN website. This is one of my test models used for checking the code. Does it exhibit the same symptions as you are describing?
Also do you or anybody else have access to the full test reports for the PRR M1 or other locomotives, as I would like to get a copy so that I can use it for testing.
Thanks

Glad to hear that it is now performing for you.

What were the issues?

I suspect that the larger more modern US locomotives will not perform well with a BASIC (out of the box) configuration, and instead that they will need to have some of the ADVANCED parameters set. Ideally a test report would be very helpful to accurately set these parameters..
I have been negotiating with the Hagley Library to obtain a copy of the M1a test report produced by PRR test station. However there is a cost associated with sourcing it, and as I don't normally model US stock, and strictly speaking don't need a copy of it, I am wondering whether some members of the community would be prepared to contribute towards the cost of this resource? It would be useful to demonstrate how to define a steam locomotive accurately within OR. WDYT?
Thanks
