Steam in Open Rails

Thank you - sir - looking forward to trying this again...


LOL - you don't get much larger than a 2-8-8-2...

Very true, but it was not even coping with the WP 2-8-2s.

The problem of running out of water and associated items such as fusible plugs are fixed in X1991. Should be in the next weekly update if you do not use SVN or James's site for updates.

Thanks for the update. Much obliged.

Hi Folks,

Had some time to run some steam last night - using whatever was the latest OR version hosted on James's site... Much better now - the injectors can keep up with steam demand...

So - I read a previous post - that mentioned we are now using some additional OR specific parameters in "Eng" files for steam locomotives ??? Do these values make a significant performance improvement ??? I'm not sure how to make the calculations necessary to determine these new values... Would someone be willing to offer a little help walking me through an example - I can post a "good" 4-8-2 Mountain "Eng" file to help...

If you open the OR Steam Model_03_02_2014.pdf in the Documents folder it lists the ORTS specific lines. Most of what you need can be found at http://orion.math.iastate.edu/jdhsmith/term/slindex.htm, no calculations needed, just plug the figures in, and the Davis equation friction figures are derived from Fcalc2. The Davis figures can be left out as OR will then use the existing MSTS Friction line.

The new ORTS specific parameters will give a more accurate performance than MSTS.
