Re: Doubleheading

This is how it is done! The in-train or rear-end helper is to always run its throttle at its maximum power and shove all the car it can while its engineeer watched the air pressure at all times.
The lead engine will work its power as to the speed it wants to obtain. The lead engine will use whistle signals to start the movement, and air brake usage to stop the movement.
The speed will be maintained by the amount of power the lead engine add to or removes from the train which is too heavy for the helper to even move.
The helper power does not have enough power to push the train off a normal track unless the brakes are improperly applied or acknowldged by the helper.
