Abstract
An apparatus that provides electrical power for the operation of analog motors or decoder-equipped motors, said apparatus comprising: e) a power source having variable voltage output for operating analog motors and/or fixed voltage output for operating decoder-equipped motors; f) a circuit for changing the output of the power source from variable voltage output to fixed voltage output and from a fixed voltage output to a variable voltage output; g) a means to vary the analog voltage output; and h) a switch to actuate the circuit and thus the change from a variable voltage output to a fixed voltage output and from fixed voltage output to variable voltage output.
