Many moons ago I got a Bachmann controller in a set I bought.
Because it was made for the American market, the transformer was useless.
I tried numerous power sources.
It would work fine. In one direction.
To make it work in both directions, I had to wire it to a 240 Volt transformer/controller.
It did give me very fine control, but was very Heath Robinson.
I just thought it was a faulty unit.
I got rid of it.
I was given some track and bits and pieces recently.
It contained another one of these controllers.
I tried it and guess what?
It works perfectly, in one direction.
Can anyone explain why they only work one way?
I reckon they would be useful, if they worked.

The only reason I can think of is a faulty switch, or not wired correctly (unlikely).
They are basic units.

I've got a Bachmann Controller sitting on a rarely used N scale layout.
It does use a wall-wart for power. 16v AC input.
Never had a problem with it.
The Controller seems very basic.
Hard to think that two units would be wired incorrectly.
I suppose you could always take it apart.

No new suggestions.
It's all pretty straight-forward so can't imagine what could go wrong.
Maybe the engine has a problem.
That could be easily checked by disconnecting the controller from the track,
and touching the terminals of a 9v battery to the rails.
If the engine moves forward and backward using the battery,
we'll know it's the controller.
