Q.—Should you break a main crank-pin close up to the wheel, how would you disconnect?

A.—Would take off all side rods and the main rod on disabled side, and run in without train.

Q.—Should you be running an engine which had a slide throttle-valve, and it would strip or disconnect inside the boiler partly open, how would you manage?

A.—Would reduce the steam-pressure within easy control, and state the trouble to the crew, and caution them to act promptly when called upon to do so. Would work the train, if freight, to the nearest siding, and back it off; if passenger, would keep the pressure within easy handling, and work the train to the nearest telegraph office, report, and ask for orders.

Q.—Should one of the forward tires on a ten-wheel engine break, how would you manage?

A.—Would jack the wheel up the thickness of the tire, take out the oil-cellar, and cut a block to fit the bottom of the box and journal sufficiently thick to hold the axle up in its place when resting on the pedestal-brace; would then run in without disconnecting, provided the rod had not been bent or damaged by the broken tire. Would take in full train.

Q.—Should you break a main tire, how would you manage?

A.—Would first send messenger to nearest telegraph office, and ask for assistance. Would then block up the axle and wheel the thickness of the tire, slack off the side-rod keys, and run in carefully without train.

Q.—Should the back tire break, how would you manage?

A.—Would take off the back section of rods, block up the axle, run very carefully, especially around curves, to nearest telegraph office, report, and ask for orders.
