Hello I bought a Hornby R383 Gordon the Big Blue engine no.4 for my son's birthday (pre-owned). Tested him a couple of months ago worked fine backwards and forwards. Got him out the box today he will not move. He makes the noise so I know power is getting to him and then the controller cuts out. Assuming something is causing a short? Other engines all working fine and the track is only a basic oval, nothing completed. I'm a newcomer to the world of model railways so any advice appreciated. Juts wondering if it is a simple fix or if I need to find a repair shop.
