O\R engine file parameters

[TGM]

Hi all,

I don't know if this is to big a question to answer, but, I got to thinking about engine files (diesel) for "Open Rails". In particular, thinking about what type of engine file (& content) is now required to be fully compliant.

If I was going to do an engine file purely for "Open Rails", what would need to be included in the file & what would need to be left out?
I would appreciate your guys thoughts on this.

regards Tom

Just as an addition to this, I find that all engine parameters in the engine files from SLI seem to work best in OR. Whatever coding is used for the sounds and lighting, inside and out, seems to work. I have found that MLT engines have some sound issues. Not knowing how modify the coding, I have been transplanting portions from SLI .eng files to others.

I feel a good start would be with a locomotive file from SLI, they seem to have scored with OR.

SLI files sound like a good a place to start.
I know there are some new parameters for the exhaust smoke, such as OR_Diesel (exhaust color), OR_Diesel (IdleExhaust) & OR_Diesel(MaxExhaust) etc. I might try a few of these & see what happens.

Nothing will happen. They were included for future use, but they aren't programmed to do anything yet.

Ok. No point in trying them then.

Only Parameters I've messed with and found were these example's for my SD70M's with special calculated effort curves.

Thanks for those. Did you notice much difference in engine performance from using these settings?

Oh yea plenty of it with satisfaction too. The brake one's pretty much help and match some realism situations I be in and watch when it comes to brake's and it's test's but locomotive model and consists vary. I sure like the traction curves and figured how I can cook and burn my DC motors under continuous speeds.

The tractive effort curves depending on model take's a lot of math and can vary depending on company software and settings.

[TGM]

Interesting. Thanks for feed back.
