A. See that brasses are properly fitted, keys fastened and nuts made
tight. If any repairs have been made on valves or valve gear, would see
that the reverse lever could be moved freely and that all movable parts
had been properly replaced; would also give especial attention with
reference to lubrication of these parts.

4. Q. What attention should be given to boiler attachments, such as
gauge cocks, water glasses, etc.?

A. Would see that the gauge cocks can be opened to try the water and
closed, so steam and water would not come out into cab. Observe the
water glass and note if water is moving up and down in the glass, see
that the steam valve at the top and water valve at bottom of glass could
be opened and closed, and allow water and steam to circulate freely
through the glass.

5. Q. What do you consider necessary to report on locomotive boilers?

A. Should report all defects on boiler and its attachments while engine
is in engineer's charge.

6. Q. Trace the steam from the boiler through the cylinders to the
atmosphere and explain how it transmits power.

A. Steam enters the throttle valve located in the highest part of the
dome in order to get the driest steam, then passes through the standpipe
and dry pipe out of the boiler to the steam pipe tee or nigger-head
located in the front end, then through steam pipes to the steam chest. A
steam valve in each steam chest distributes the steam so that it enters
the cylinders at or just before the beginning of the stroke; pushing the
