Thanks. Interesting thread! I admit to being quite surprised when I first picked up the Hornby train set controller. Very light.
It only happens when I stop the train. I could run it for a few minutes, speed it up, slow it down, speed up again, then stop the train. Then when I go back to it, maybe a couple of minutes later, maybe only 30 second later, the controller won't work. I might have to unplug it a couple of times before it will work again.
Odd.
