    ORTS Diesel Engines Block

    Here's three for comment and critique, if you have changes or suggestions, please try to include references or supporting docs.
    I know there's a lot of experience out there, so the whole lot should be able to fine tune these initial offerings into something all can use.
    I'll post some more every few days or so.
    NOTE: to anyone comtemplating using these, remember it is just as important, maybe more so, to have accurate ORTS Davis numbers, and the CurtiusKniffler line in the engine include file. These can greatly affect engine performance.

          Gerry, where does the data come from for these locomotives? Seems like pretty arcane stuff.

              I cobbled them together from all the engine files I could download from ET and TS libraries, and what I already had in my master trainset.
              I dump the obviously incorrect values and then compare what I've got to the data in the web sites below, along the way accurate numbers begin to emerge. As I learn more and read threads, I re-visit the files, revisions are a way of life.
              For instance a couple of the 44 tonners had max power in excess of 3000kW - excessively high, easy to dump those values.

              and from these web sites:

              The Diesel Shop
              http://www.thedieselshop.us/
              The home to first generation locomotives photos, data and history, and central location for over 475 current locomotive rosters.


              Operator Manuals
              http://www.rr-fallenflags.org/manual/manual.html


              Wikipedia, the free encyclopedia
              https://en.wikipedia.org


              http://www.rr-fallenflags.org/manual/44ton.pdf >>> I loved the illustration "How a Diesel-Electric Functions"

              I wanted to make the 44 tonner a two engine block, but I'm having some troubles with certain locomotives DD40AX especially, that use an OR diesel engines block with 2 engines. I'm trying to figure that out.
