The switchboard
allows various configurations of the equipment. Using
it, the office
can be shut down and the equipment protected from
lightning. The
station's equipment can be connected to, or
taken off, the main
line. Various configurations can be set up to help
linemen test for
telegraph line faults or breaks. Little metal pegs are
inserted in the
holes make the connections between two conductors. The
instrument wires
come off at the '8 o'clock' position of the
switchboard.
The wall-mounted, pivoting coal oil or kerosene lamp provides light for clerical work at night. The telegraph relay (to over-simplify) is an electromagnetic audio 'amplifier' of the main line current. The telegraph sounder produces the sounds which the telegraph operator decodes as letters and numbers. Generally, experienced operators recognized the 'sound of a letter' ... instead of 'hearing' and counting up the clicks and clacks of the sounder as a message was being received. As the operator must perform certain duties outside (such as delivering orders to passing trains or setting the train order signal) placing the sounder on the window sill ensures he will hear and be able to respond to any railway messages requiring his immediate response while out on the station platform. The telegraph key and the
local battery are the two pieces of equipment not
shown.
This simple communication equipment described is well-suited for receiving the precise time ... relayed from the Dominion Observatory in Ottawa. The equipment can be used to relay train orders from the dispatcher (located at large settlement 5 to 200 miles away) governing the movement of passing trains. When the operator and equipment are not busy with railway business ... local people or travellers can send and receive personal, commercial, and official information ... for a fee, of course. Unlike some European railway telegraph equipment, this equipment requires the operator to be proficient in receiving Morse code by ear and he must be capable of sending with accuracy and speed. The equipment is cheap enough that spares are available in quantity. Replacing equipment is done quickly and easily ... by loosening or tightening the thumb screws which secure the conducting wires. |
