Hi Folks,

Question - are the tables on Peter's "Coals To Newcastle" site - the definitive list of what ORTS actually uses in the ENG/WAG files ? The tables he compiled are fantastic as they indicate whether it's a new/existing parameter with examples of actual usage... The following is the full list of parameters I've compiled from the tables I could find on his site... I couldn't find any for "Electric Locomotives" - so if someone has those parameters - please post...

So if not defined in the following quote - they're not used by ORTS ?

In order to make accurate physics files - we certainly need the definitive list of which parameters ORTS actually uses...

My point of confusion - is that after putting together this list - I found an example for Diesel Physics in the ORTS manual and it had a plethora of values not indicated in the tables ?

In the quote below - each parameter is listed - followed by an "x" for existing or an "n" for new - followed by any specific keyword input - if required - by the parameter...

Any mistakes or omissions - please let me know...

Note - See below.


Regards,
Scott

Hi Scott
The list is indeed longer.
There are parameters for gears for diesel mechanical transmission.
There are parameters for dynamic brakes (and blending them with train brakes).
As to electric traction - relevant parameters that apply to diesel (electric) also apply to electric. I don't think there are any additional parameters available yet.

Hi Darwin,

Thanks for responding...

Sooooo - LOL - how do we flesh out this definitive list ? I think it would prove - immensely - useful to the community and modelers for numerous reasons - as if we don't know what works and it's never been documented - ORTS physics is still a bit of an arcane art...
:)

Is there some other means of identifying active parameters - short of crawling through the code - available to us ? If we can do this - it probably should be added as an appendix to the ORTS manual...

OK - I added a bunch more (in an Open Office Spreadsheet):

Scott, many of the parameters listed have an "N" (new) after them, but they have been in use for at least 3 years...? ORTSMaxTractiveForceCurves for instance.Also, if a user is employing the Common.inc folder with the ORTS Diesel Engine definition, then the Diesel Smoke Effects parameters are not used.
The only usable parameters from Diesel basic ( if one is using the ORTS Diesel Engine definition + ORTSMaxTractiveForceCurves ) are:

• ORTSDriveWheelWeight x
• ORTSWheelSlipCausesThrottleDown n
• ORTSDieselEngineMaxPower n

[Genma Saotome]

Perhaps n should signify not MSTS.

I agree, that we need definitive lists, and I have done the best that I can, but documentation is definitely not a one man task, and hence the occasional requests for additional members to form a team to help.

I also believe that it is important that people can access examples to use when configuring locomotives. I have also attempted to provide these as well on the CTN site, however with changes in OR functionality they slowly go out of date, and need revision from time to time. These example models also form a quality check to determine whether bugs have been introduced.

[darwins]

It looks like we already have a bit of a team here for this task.
If Scott and myself revisit the list a couple of times - then try to put it all together perhaps some of the coders and OR lead people could check through the list and add as an appendix as you suggest.
Should we aim for something like Rudolf Richter's eng and wag file manual for MSTS eng and wag files - or is that too detailed as things should be documented in the body of the manual anyway?
Also another appendix creeping up on us must be using bits of code to include train control and warning systems. I think the French have already produced some for TVM430 and KVB.
It would be good to see some British ones GWR-ATC, BR-AWS, BR-TPWS, BR-TASS, BR-ATP and for all around Europe and the world various forms of ERTMS.

Hi Gerry/Dave,

Sorry for being vague - I'll update the spreadsheet - [x = existing MSTS value] [n = new ORTS value]... I'll label them better...

I was hoping you would pipe in here Gerry - I know you've made a herculean effort on getting the diesel physics worked out - and that's an area where I know very little...

I know I'm missing a bunch of the diesel braking parameters...

Scott

Hi Peter,

RE: http://www.coalstonewcastle.com.au/

You've certainly championed this cause more than anyone I know - your site is an absolute gem - there is so much useful information there (not to mention all the specific value calculators) - I don't know how I would create a physics file without it... I've only been hitting it heavy for the last year or so - after I realized how much it contained - but I still find something new every time I visit... Thanks for doing it - seriously...

Fully concur on "not a one man task"...

Regards,
Scott

Hi Darwin,

Sounds good to me... I wish we had a way to collaborate a little easier on this but attached is my Open Office Spreadsheet... If people make additions or deletions - in a new color - then send it back to me - I can certainly try to keep a master sheet updated with the intent of adding it to either the ORTS Website or Manual - - - or both...

Is there a way to visibly post spreadsheet contents on this board (aside from an image) - in a thread ?

What set me off down this path was a simple need to make an ORTS compliant language (syntax highlighter) for Notepad++ - that way - when you open and ENG/WAG file in the app - you clearly see which lines of code are still relevant - whether they originate from MSTS or ORTS - that you are using valid keyword arguments - provide a "type ahead" capability - and to minimize "typo's" when editing same... LOL - I'm on a mission to purge all the legacy MSTS code that's not longer used from my files...

Obviously - this can satisfy a much greater need as well...

I'd suggest we keep at as simple as clean as possible to start with - just so we have the best chance of completing it - or would it be more work to go back later and provide working examples and such ?
