Mine also relies on a further pair of reed switches to provide reverse. The loco would also require a further reed switch or on off switch to ensure the battery was isolated as finding the centre off position would be challenging. Operation would press one way for increased speed and the other to slow and then reverse and so on. The big advantage of this is that the loco continues at the same speed if it loses radio signal, Most systems stop the train when contact is lost which is completely useless when you have 2 metre long tunnels under the rockery as I have

So simple. I would have liked to use the RC capacity of the two RC sets as per Newman’s suggestion, but your fix is certainly the way to go for the four manually operated locos

Thanks Newman,
I’ll give that a whirl It sound like with this set up I’ll be able to run the loco from the hand unit. Am I right?,

So for simple manual speed control, I suggest a PWM speed controller (much cheaper). Many electronics suppliers will have these. Make sure it has sufficient voltage and current capability.
Just two wires in from the battery, and two wires out to the motor.

For example:

Find a rheostat that can be added in into the wiring at your engine or tender. Put that rheostat onto a RC Throttle servo and run it like a RC plane if this is the case. I would try the rheostate first and see if it will do the job. Probably one from Radio Shack possibly.
