Diesel Mismatched Lash-ups

Former Member

I've always wondered how lash-ups of different types of diesels worked together. In the latest issue of Classic Trains, there are some photos of Alco, PAs, FAs and an F3 B unit as the motive power for a train.

I can almost understand, though not fully, how one manufacturers different locos can work. However, with the combination I mentioned in my first paragraph, how do the units coordinate as far as speed and pulling power ?
