The railroad then developed a more effective system consisting of wooden balls, painted red, white or black, and hoisted up or down a pole on a rope-and-pulley system. The initial use of these signals was merely to indicate the on-time status of trains, rather than to control train movements.
The signalling system used on the rail transport in Norway is regulated by the Regulations of December 4, 2001 no. 1336 about signals and signs on the state's railway network and connected private tracks. The first signalling system on the Norwegian railway system was a mechanically operated semaphore system introduced at Drammen station in 1893.
The final 'Call-on', Shunt' or 'Warning' arms on the Western Region were 2 feet (0.61 m) with red-white-red horizontal stripes and showed a reduced light during darkness with the appropriate black letter, C, S or W, back-lit in the 'proceed' state with a green light shown in that mode. The stop aspect was generally lunar-white during darkness.
A railway signal is a visual display device that conveys instructions or provides warning of instructions regarding the driver's authority to proceed. [1] The driver interprets the signal's indication and acts accordingly.
This sign is a blue square board with a white St Andrew's cross on it (or a yellow board with a black cross, if provided in conjunction with a temporary speed restriction). With mechanical signalling, the AWS system was installed only at distant signals but, with multi-aspect signalling, it is fitted at all main line signals.
These consist of a black background, mounted under a single stop signal, on which is superimposed a white letter(s), number(s) or combination of the two, to make a code indicating the route to be taken. For example, if the possible routes were to Cambridge and to Norwich, a Norwich-bound train might be shown 'N' and a Cambridge-bound train 'C'.
Originally, the light signal with the name Sh 0 had two white lights mounted horizontally. In conjunction with changing the lights to red, they received mast shields similar to main signals, serving as fall-back in case of their failure. as semaphore signal: A white circle with a black line horizontally across it, mounted on a black box.
