It might not. I don't like doing that cuz IMO it'll strain the 317 regulator
to put out what it's supposed to. Even if it could put out 9V with a 7.5V
supply, I can't imagine the current remaining the same. I know we're using DC
loads, but we don't want to have to worry about more than one motor on a track
overloading the circuit, esp. since more than motor usually indicates a
loooong (and therefore heavy) train. Maybe someone who has done it can shed
some light if it does indeed work.
