Hi, sorry if this has been asked before, but I’ve recently purchased a Hornby industrial train set, wanted to get into model trains for years, had one as a child and loved it, my grandad put everything together for me as I was young so basically a newbie, the set was second hand but in immaculate condition, I’ve set it out for a test and it goes great, until I came to change points (basic oval track with track pack a included in set) it went once down siding, then tried again and the controller cut out, every time I try it, the controller cuts out, any help would be gratefully appreciated. Jase.
