Diesel-Electric boats can run off just the batteries for dead silent
operation.
Nuke boats will still have cooling pumps and such and present a much larger
acoustic profile.

Trains can have up to 20 or 30 wheels driving if several locomotives are
coupled together (to get over mountain passes, etc...)
Do you want to design that mechanical transmission or differential?  <grin>

Each wheel gets an electric motor.  Trains do not use regenerative braking
(diesel has much more energy than lead/acid batteries by a long shot so a
decent regen braking system would require that the train consume more fuel).
They do run the wheel motors as generators and dump the energy in large
resistor banks located at the top of the locomotives.
