It's a pre-owned model, fully working as i was told - Bachman Class 37
Just bought it yesterday at the London Festival of Model Railway.
Yes, I can control it fine, some other functions work fine, but I notice that some functions don't do anything. According to the paper sheet that came with the loco, sound was fitted by YooChoos.
Yes, I did receive a paper sheet with the functions and what they do. Not all functions work, so I am now thinking that the item may not be fully working.
I'm afraid I do not really know what you mean on points 1 and 2. Really novice here.
