Is it an old version with screw-in (yellow) bulbs, or a more modern one with the push-in 2 pin bulbs?
If the former, you should be able to gently slide the entire bulbholder down out of the bottom of the lamp housing, unscrew and replace the bulb and slide it back into place again - there should be enough play in the wires to allow this; if the newer type, then carefully pull the bulb out with a pair of pointed tweezers and push in a new one.

Well, there you go, that's what G-scale is all about. With some confidence after your message Jon instead of going for the hammer and chisel I got my long jawed pliers and very gently removed the bulbholder, unscrewed the bulb. the filament did not, on close inspection, seem to be damaged and anyway my spares are out in the garage and it is a very cold night, I'm not going out there again, so I just screwed the bulb back in and ran the tram. Guesswhat, yes, it works. So plugged back in and we are running OK. Loose contact?
