AUTOMATIC ALARMS AND SAFEGUARDS

CRANKCASE OVER-PRESSURE SWITCH
(Figure 5)

A crankcase over-pressure switch is mounted on the side of the engine near the generator. The switch will shut down the engine in case a serious engine fault occurs.

When the switch trips, the engine shuts down automatically, the alarm bell rings and an indicating light comes on in the operator's cab and on the housing of the switch.

When such a fault occurs, take the locomotive off the line and leave the engine shut down. Proceed as directed by railroad rules.
