4) Obviously "old fashion" DC traction motors?

Why?

Current locomotives use a AC-DC-AC transmission where AC produced by the generator is rectified to DC. The DC is fed into a variable frequency drive which feeds AC at the desired frequency to the asynchronous motors that drive the wheels.

In the case of a battery powered locomotive the DC from the batteries is fed to the VFD which then supplies AC at the desired frequency to the asynchronous motors that drive the wheels.

The unit is propelled by AC motors.
