Hi andyf, It's gas fired with butane or butane/propane mix. The gas tank is located in the rear bunker, a dummy coal load, cast out of zinc hides it nicely. The coal load pulls away revealing the filler valve so that you can re-gas it. To fire it, you open the gas valve in the cab and hold a lighter or match just over the chimney, the gas ignites (small pop

) and then its just a 5 min wait for the safety valve to blow off (40 psi) and off you go

Thats a good idea Russell, I will bare it in mind

Cheers
Rob
