89. Q. How can an engine be brought in with a broken front end or stack?

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.

91. Q. If the frame is broken back of the main driver?

A. Do not disconnect and do not try to pull a heavy train; it is safer
to come in with light tonnage.

92. Q. In case of broken side rods, what should be done?

A. Take down the broken rod and corresponding rod on the other side of
the engine.

93. Q. What can be done if the intermediate side rods were broken on a
consolidation engine having the eccentric on the axle ahead of the main
wheel?

A. In this case the engine must be towed in. It is possible when the
main pin is broken, so that all rods on one side are taken off, to leave
the rods up on the other side and move the engine with her own steam,
but very few roads will allow this, because engineers will be inclined
to leave the main rod up on the disabled side to prevent engine catching
on the center. If main rod is left up on the disabled side, the wheels
will surely slip and wreck the rods on the other side.

94. Q. Should one of the forward tire, main tire, intermediate tire,
back tire, or a trailer tire break, what must be done to bring the
engine up?

A. Would run the wheel of the broken tire on a block in order to raise
the wheel clear of the rail and the box up in the driving box jaws.
Remove the oil cellar and place a block between the driving journal and
pedestal brace to carry the disabled wheel center clear of the rail.
Would also block up on top of the box of the wheel ahead or back as the
case might be, in order to take the weight from the disabled wheel. It
might not be necessary to take off any of the rods, but would run the
engine light to the shop, giving special attention to lubrication of the
disabled wheel and using extra precaution in entering side tracks and
passing over frogs and switches. With the tire of a back driver or
trailer wheel broken, it is usuall
