engineer?

A. In starting an oil burning engine the oil should gradually be brought
up as the throttle is opened and the movement and amount of oil should
be kept slightly in advance of the action of the engineer in order to
prevent an inrush of cold air as the engine is working, which would
result in injury to the fire-box and flues. When the throttle is to be
closed, the fire should be reduced very slightly in advance of the
closing of the throttle. This is to prevent the engine from popping off
and black smoke drifting back over the train.

14. Q. Is it necessary that the engineer and fireman on an oil burning
locomotive work in perfect harmony and advise each other of intended
action at every change of conditions?

A. Yes; they should work in harmony with each other on any locomotive.
The fireman should watch every move the engineer makes, and the engineer
should advise the fireman of every intended change of the throttle, so
he can operate his valves accordingly and save fuel and avoid black
smoke.

15. Q. What is the effect of forcing the fire on an oil burning
locomotive?

A. Forcing the fire is very hard on fire-box sheets and flues, and will
cause them to leak. An even temperature should be maintained in the
fire-box of any locomotive.

16. Q. Is a careful regulation of steam and oil valves and dampers
necessary to obtain the most economical results?
