Doubleheader always referred to two (or more engines if tonnage required or 
power needed to be moved to another terminal) engines coupled at the head end 
of a train.   Regardless of the number of engines coupled, only the brake valve 
of the leading engine was allowed to be cut in, that is, the brake valve on the 
lead engine handled all the braking requirements of the entire consist.   The 
lead engine must be used to start the train, if possible.   If it won't start 
the train the second engine may be used to help after the lead engine has 
streched the slack as much as possible.

Pushers, though not a doubleheader, must shove against the train in an attempt 
to start it after the signal to start has been received.   If unable to get the 
train moving the pusher Engr. will signal the head end with two long whistle 
blasts.   The lead Engr. will then carefully begin pulling on the train until 
everything is moving.

The success of train handling with a pusher (no radios) depends heavily on the 
pusher Engr. knowing the territory and, if possible, the train handling methods 
of the lead Engr.

With the advent of MU connections on Diesel locomotives doubleheading became 
the stuff from which "thrilling" Tales of the Rails were gathered.
