A simple way to reduce voltage to the cars is using diodes.
Each diode will reduce the voltage about 3/4 of a volt (the exact voltage drop depends on the load)
For AC, two diodes are needed connected in opposite directions.

You could have a rotary switch with one diode step at each switch position. Quite a few guys have built these for reducing the voltage on DC track power. For AC you need a pair of diodes (one connected each way) at each step.
