60. Q. If the light goes out while between stations, what course would an engineer pursue?
A. If investigation cannot be made within a few minutes thereafter to determine the cause, the steam should be shut off from the turbine engine until such time when cause of failure can be determined.
61. Q. Why is it essential to shut off steam and stop the equipment?
A. If failure was due to a short circuit, damage might be done to the armature or field coils by overheating.
62. Q. How does the equipment act when short circuited?
A. The engine will labor heavily and run slowly with a large volume of steam blowing at the exhaust, the carbon points and cab lights will only show a dull red light.
