Hi I was just wondering about the pros and cons of heating my 3 1/2 " loco boiler with a gas burner instead of coal. What would be best? butane or propane. Would the exhaust steam draw through the boiler to much and suck the gas flame out. Can anyone give advice on this idea one way or another. Look forward to replies to my odd question. Garry
Built a Stuart Beam engine and a 3 1/2"g William 2-6-2 steam locomotive. Just starting on a 2" scale Durham & North Yorkshire traction engine.
You can pretty much rule out butane because its going to be difficult to obtain the quantities you require and a reasonable price.
You will be able to get LPG fairly easily obviously but its going to cost a pretty penny to run the loco.
Pros Char: Char is cheap, reliable, prototypical, you dint need to worry about gas leaks, you wont have to carry a fire extinguisher with you (Australian rule). a day on the track wont cost you $60 bucks in gas. ;D
Pros Gas: you can cut the fuel quicker, money will stop burning holes in your pockets. Coal smell will be replaced with LPG smell, you wont need a coal shovel ;D
