OPERATOR'S STATION
BLACK OUT DRIVING LIGHTS CIRCUIT
Power for the circuit is through the 60 amp circuit breaker, and a 15 amp circuit breaker, then to the light
switch.
When the light switch control levers are in the "B/O LIGHT" position, power is sent to the black out driving
lamps and not to the coil of the magnetic switch. Because this switch has open contacts, no power is sent
to the terminal board where the normal driving lights and panel lights derive their power. Power is also
sent to the black out stop light switch, which operates when brake system pressure is sufficient to close
the normally open contacts.
