Beginner’s guide to live steam butane-fired locomotives. 

What is the area that you put the butane canister on to fill it with gas called?

@jeff shackleford the sheat of iron that makes up the cab floor is called the footplate on the ruby the gas bottle thread stud goes on the left on the rear hole the displacement lubricator goes over the front hole careful they are easy to strip the threads on, I found its best to place a small donut of electrical tape around the bottom rim to help prevent it from rocking and turning lose I also found that the bottle get too cold fast and that cutting a heat sink to the height of the bottom of the gas bottle ID plate and bending it around a slightly undersize sanded wood cylinder to a snug fit on the gas bottle and placed on the boiler facing side and tied with thin wire helps the gas absorb heat to boil faster and feed the burner in cool environments [edit] butane gas filler valve m5 sorry just woke up and didn't comprehend what you were asking until I woke up :)
