Diesel locomotives are still powered by electricity. The Diesel engine runs a generator which provides power to the traction motors on the rail. The same concept can be applied here to Hydrogen.

I'd say "powered by diesel but moved by electric motors"

Trains have different requirements in terms of how power is applied to the wheels, and the loss of efficiency is acceptable in this context.
