Alright so, one thing has -really- bugged me about editing Steam Physics, and that's the fact that the site steamlocomotive.com shows physics fields for the locos like Tractive Effort in lbs, 'Factor of Adhesion', and these different power computations. IS there a way to impliment those into ORTS? I've scoured the manual and Steam Model PDFs and can't find anything for a field like say, ORTSTractiveEffort ( XYZlbs ), ORTSFactorOfAdhesion ( 123.4 ), etc etc.

There's got to be a way to do this; however the problem I have is, if this pertains to the old MSTS Archaeic parameters of:
MaxPower ( 2222.22kW )
MaxForce ( 324kN )
MaxContinuousForce ( 316kN )

For example, how the fudge to I convert that stuff? LBS of Force doesn't seem to be convertable to HP, KW, etc... Not to mention with having Dyslexia, it makes it difficult to understand some of these things.

So, help..?

I can't figure this %&*$ out, honestly.. I'm ahving a severe issue trying to set up the physics that would match the PRR T1 that's being developed, and this thing is WAY too dang powerful... What the flip do I do, and what am I doing -wrong-? I'm going off of the stuff here: http://www.steamloco...uplex/?page=prr

[ALso posting the entire .eng here, as I can't seem to find a file-attach option...

NumCylinders ( 4 )
CylinderVolume ( "18.437986112*(ft^3)" )

With those two you are saying all cylinders receive the same pressure of steam. But that's not true of most compound locomotives... normally there is one pair of low pressure cylinders, and by low pressure I mean well under 50psi kind of low. That's your first problem. Your second problem is courtesy of KUJU, who did not provide the data parameters LowPressureNumCylinder(), LowPressureCuylibderVolume(), and Low_PressureSteamPSI(). AFAIK, neither has Open Rails. And what that means is the locomotive has to be presented tot he game as two locomotives -- a double header so to speak... but then you run into all sorts of other issues like distributing the weight.

My advice is to doa quick review of other compound locomotives and seekthe advice of people who have built those kind of models and creted their .eng files.

Good luck.

I'll look into that for sure; however the interesting thing with what you will notice about the T1 per that site, is apparently neither the T1 or the S1 had low-pressure cylinders, only high pressure ones. I am unsure if I can 'split' this engine, either, as I do not think the final T1 that Nicolas is making will be a split engine, either.

The tractive effort for a steam locomotive in Open Rails is calculated by the code. There is no entry in the eng file to define it in the way that MSTS uses. Compounding is now part of the Open Rails steam locomotive operation and is covered in the manual. The locomotive is declared as a compound, and has specific low and high pressure cylinder data in the eng file. I don't have a worked example of the compound yet, but do have one for the simple engine, this was done by steamer_ctn who is also the author of the current steam code. It seems that the facility to attach files here has been removed so cannot add it to this post.

But if you go to http://www.coalstone...form-test/#loco you can download the test locomotive that includes 4 different eng files, two of which are specifically for Open Rails only. They should show you exactly what Open Rails needs in the eng file.

Far as 'split' engines are concerned, I do not like them. The only reason they exist is to get them into MSTS without sacrificing too much detail. There have been several articulated engines made for MSTS as single models and they work very well, but they are of smaller prototypes. Now we have Open Rails, there is no real need for multi part articulated engines of any power type.

You have some glaring mistakes in there already I believe . I've run the old T1 model from many years ago with my OR eng file and I think you should look at a lot of your numbers and quantities . Why not check the " Sample " files on Coals to Newcastle and go from there - makes it an awful lot easier - almost like filling in the blanks . BTW - Don't split it .
Just a suggestion !

For Open Rails to develop the correct TE the eng file must have the stroke and diameter figures as well as the number of cylinders, but does not need the volume figure.

just a comment here...........................

The tractive effort given for most (all?) steamers is calculated (Note 1) as is in fact most TE's for diesel elecetrics. Due to the nature of steamers the actual real performance can be a good bit different, steamers in real life being quite variable machines. Engines of a single class each having its own personality.

Note 1: So they way OR does is quite reasonable, one DOES need to set up the eng files well, this is not really a task for the faint hearted. The example eng files on Peter's site being a mine of infomation, as is often the case though in open source world the code is usually a good bit ahead of the docs.

Mind explaining some of the mistakes, then..? And where can this Coals to Newcastle be found? What 'Sample' file? Kind of vague there a bit. ^^"

AH, that'd explain why messing with some of the options didn't do anything, then... Well lemme ask, based off of the cylinder number, diameter/stroke, do you think this locomotive would have a rather high acceleration? Because that's what it seems to have. A almost alarming amount of acceleration. I have no idea if it was prototypical for the T1, but, it just doesn't seem right to me.

If you go up 5 posts you will see a link I posted for the CTN site. The file you need is at the bottom of the page.
I would imagine that the T1s had a rapid acceleration if pushed and running light, a bit slower with a consist in tow, but still quite rapid as it is rather similar to having two locos double heading in the design concept.
