I would think adding a bridge rectifier would be the same as running on DC and would not reverse the motor.

If you isolate either the armature OR the field and run one of them with a FWB full wave bridge rectifier, then it will reverse with a change of DC polarity on the track. The armature & field still need to be in series... if they are shunted, you will draw too much current. I've done this, but the performance isn't spectacular.
