I'm new to all this. I had a train set as a kid and I'm just starting up again.
I have a Hornby Class 121 R2509 Bubble railcar and I can't get the casing off to fit the DCC Decoder. Undoing the screws is simple but whatever I try I don't seem to be able to remove the body from the chassis. The instructions simply say ease the body outwards and then lift up (or words to that effect). Where are the locating lugs or whatever it is that is holding the body in place or do the screws do that and it is literally a case of lifting the body off?
