A. By boarding up the front end to make it as near air tight as possible
and using a barrel or a petticoat pipe in place of the stack, wiring it
fast to the smoke-arch. Where a portion of the stack is inside the
smoke-box the engine might steam without the barrel or petticoat pipe.
90. Q. What should be done if the frame is broken between the main
driver and cylinder?
A. Either give up the train and come in light, or disconnect the engine
on that side and come in with reduced tonnage, depending on how badly
the engine pounds when working steam.
