Railroads tried to avoid it early in the diesel era because the traction motors of locomotives from different builders loaded differently. When a PA and E8 were together on a standing start, one would literally yank (or shove) the other until they hit 15 - 20 mph, that was the difference in their standing start acceleration curves.
Later, as first generation diesels went away (or railroads hit hard times), it didn't matter - just lash together anything that runs and move the train. As far as I know, only the Baldwin's were different. They had pneumatic MU controls as opposed to electric. They could not be MU'ed with other builders. When you see them together, they were being operated as a true double headed train... Luckily (or not!?!) model railroaders don't work under the same constraints... <G> Jim Kindraka P.S. Sorry for responding after the thread has pretty much died, but I can't participate in this until I get home in the evening... --- In [email protected], "Tom Hawley" <t.haw...@...> wrote: > > How careful were they not to mix manuracturers?
