An English style CAB a-la GaugeMaster. It needs a center tapped transformer of up to 24volts. The speed control must be a linear potentiometer as center position is zero power.
No short circuit protection but a push button could be included in the output to remove power if there is a short across the rails. No reversing switch is needed. The transistors must be on heat sinks.
------ Running report
Some Dead Band on the control. Satisfactory slow speed running. Jumpy starts.
