119. Q. How are accidents and breakdown best prevented?

A. By inspection both at and after leaving terminals, frequently while
on the road, keeping all parts properly adjusted, water in the boiler at
the proper level and using good judgment in the handling of the engine
and train. It is much better to use care and prevent accidents than to
make repairs after they occur.

120. Q. What are the duties of an engineman when leaving his engine at
the terminal?

A. Place her on the proper track to be turned over to the hostler, leave
throttle closed securely, reverse lever in center notch, cylinder cocks
open, and lubricator feeds to steam chest and cylinders closed. The
boiler should be full of water and sufficient fire to maintain steam
pressure until fire is knocked out. Call fireman's attention to anything
of special importance. Inspect the engine very thoroughly, ascertain
whether any tools or signals have been lost on the trip and make a full
report of the condition of the entire locomotive.

121. Q. What is the most important bolt or nut on the locomotive?

A. The loose one. It should be cared for immediately.

122. Q. In reporting work on an engine, is it sufficient to do it in a
general way, such as saying: "Injector won't work," "lubricator won't
work," "engine won't steam," "engine blows," etc.? Or would you report
each special defect so it could be located after the engine was put in
roundhouse or on designated track whether it had steam pressure in
boiler or not?
