I have always wondered how the railroads, I mean the engineers & firemen, operated a double header. I know that each engineer operates his engine separate from the other engineer, but how did they coordinate the start up, increases and decreases in speed and stopping? Were there some kind of signals between engineers to let them know when changes in speed were being done. How did they know that one engine was, say, running at 20 mph and the other would match that. I have never seen anything about this in any mags. I am more curious about this when the 2nd engine was at the rear of the train. If not coordinated properly, the pusher could easily run the consist into the lead engine causing a derailment.
