What are the electrical limits of 9V trains? From Simon Robinson: ! The controller supplies a variable voltage. As you move the speed regulater from zero to the first of the 6 marks the voltage jumps up to about 3V. It then increases linearly up to about 9V for the maximum speed. The motor power unit has a resistance of 8.7 ohms, so at maximum speed, its using about an amp, which works out to 9 watts of power. For a typical controller, expect:
