Electrical Systems of the North Shore

DANGER! 600 VOLTS

Note: This page is under construction. Not all components have been marked, and those that have may be marked incorectly. For the most, markings correspond to how the equipment was marked on the car. Photos may also be from different cars.

Above: Ceiling of cab, Cab heater switch on left, controller breaker and reset on right.
White Switch is to switch between platform lights and signbox lights. Red box at left
contains 10amp fuse for cab heater




Above: Cab Layout Diagrams (Note: Reverser, brake, and sander handles not inserted)
Portable heater switch contains 10amp fuse for heater

Above: A control circuit jumper for between cars


Above: An 600v electrical bus jumper for trailers without poles
(note: the north shore had several coach trailers as well as diner/tavern and observation trailers)

Below: Heating elements in main car heaters along the floor.




Below: The blower motor for the forced air heating/ventilation.
Black Caps are brush holders, gold cap in middle is one of the grease cups.


Below: The box with the thermostat resistors/controls in it. Markings indicate
35 and 55 degree overhead heat, and 70 degree floor heat. The box just above
is the air intake, in the steel window plate.


Below: The cases with the heat control relays in them. The bracket on the wall
supports the case around the blower when it is open.


Below: The inside of the heating relay case, Railway Utility Co. Type 1900 Contactor.
From left to right, relays A, B, C, and D. In some cars, relay E is also in this
case. In this car, relay E is in a small box directly above this one.

Turning on switch 1 engages relay A, sending 32 volts through B to blower motor. When
B closes 600 is available to C and D, which close based on temperature and engage one
or both heater elements is blower.

Left is the charging relay, center charging clock, right emergency light relay.


Below: An example charging resistor made of chromalux strips, created by the North Shore.

Important Note: There are exposed 600 Volt connections on these boxes!!
