First - apologies if this subj has been posted previously. I did a search and nothing turned up about this specific item.
Recently downloaded, installed and tried to run using raildriver control in ORTS (Vx 2007). Keyboard controls work just fine. Engage raildriver and ORTS goes to grey screen. Locomotive loads with digital throttle setting (in cabview) set at "8". No worries, just troubleshot eng files and found all throttle entries missing under EngineControllers. Copied same from some other SD70M and added to eng file. (Hope I have the correct values - are there different ones for each specific type of diesel engine?) Load ORTS and raildriver engages properly and engines run using RD control. I'm new at this stuff, so I may have missed something, any advice accepted. (file download name: up70m_n1.zip)
