Unresponsive Bachman 47

[uk_pm]

I have just taken delivery of a new Bachman class 47, factory sound fitted. It has been run in, and functioned perfectly.  I stopped it in front of me, went for a coffee, and now it won’t move. The sound works (and reacts to movements of the throttle), the lights work (and change direction on command), but it will not move. Any suggestions (other than unscrew the body and check the connections)?

 

all thoughts gratefully received.

If the lights are working, power must be getting to the decoder but it's possible that the decoder has worked loose from some contacts. (I don't know how the decoder is plugged In). I would suggest ensuring the decoder is seated properly on the contacts as a first step. So it's unscrewing the body...

Thank you Griff. Alas, all the connections are fine. I’m perplexed and will send it back if I have to, but it’s such a fag (and at £290 I shouldn’t have to)!
