You may be able to use the 4amp reverse unit. Are you familiar with running pullmor motors using the combination brush-field winding method? To do this you are not running on the track, you support the trucks either on rollers or small wooden blocks and tie one field winding to one brush, and do the same for the other field and brush. You need a transformer with a volt and ammeter to check this. I recently did this with an American Flyer Alco, each motor pulled 3.8amps and the field windings got hot. When I tied them in series (together) one going forward, the other in reverse, the current dropped to 2.0 amps and the field windings did not heat up bad at all.
The easiest way to explain this is as follows. Take one brush and one field winding- call it #1. Take the second field winding and other brush - call it #2. Do the same for the second motor. Tie #1 from one motor to #2 on the other motor and run them together. One motor will go forward, the second motor reverse, just like in your locomotive.
Try it.

You've lost me Bruce. Not sure what running the motors in opposite directions means.
I have been thinking of getting an AMP meter. Would you recommend what to look for ? I don't want to spend alot on one, but I want to be sure to get one that isn't junk either.
