The motors will be set up from the factory.
I just figured you would run 2 of the same motors.

The resistance of the windings is fixed, the reactance is varied by the current in the rotor and stator. Varying the voltage and frequency to the motors will be your torque regulation.
There are other tricks to get higher torque such as putting series winding in parallel for starting. But this is a special class of industrial motors, I don't think traction motors use it.
