Swedish Railway Signalling - Main Signals

Main Signals

The main signals (huvudsignaler) display the following aspects:

Stop Proceed 80 km/h Proceed 40 km/h, caution Proceed 80 km/h,
expect stop
Proceed 80 km/h,
expect proceed 80 km/h
Proceed 80 km/h,
expect proceed 40 km/h
Proceed 40 km/h,
short route

The aspects may seem a little inverted, since a single green light means proceed 80, two green lights Proceed 40, caution and three green lights stands for Proceed 40, short route. In other words: more green means more cautiously. The speed limits apply to trains without Automatic Train Control (ATC) equipment. ATC signalling typically allow higher speeds.

Stop (Stopp in Swedish) means that the signal must not be passed without permission from the traffic control. During shunting operations permission to pass a home signal displaying stop may be given with a radio or with a dwarf signal.

Proceed 80 (Kör 80) authorises the driver to pass the signal at 80 km/h or at a higher speed given by the ATC system.

Proceed 40, caution (Kör 40, varsamhet) authorises the driver to pass the signal at 40 km/h (25 mph) or at a higher speed given by the ATC system. The next signal might be displaying stop if it is farther away than 450 metres, so the driver must approach the next signal cautiously and be prepared to stop short of it.

Proceed 80, expect stop (Kör 80, vänta stopp) authorises the driver to pass the signal at 80 km/h or at a higher speed given by the ATC system. The next signal is displaying stop, so the driver must decrease speed and approach the next signal prepared to stop short of it.

The next signal is between 800 metres (2,625 feet) and 3,000 metres (9,840 feet) away. If the distance to the next signal is more than 3,000 metres, a separate free-standing distant signal is used to govern the approach to that signal.

Proceed 80, expect proceed 80 (Kör 80, vänta kör 80) authorises the driver to pass the signal at 80 km/h or at a higher speed given by the ATC system. The next signal is displaying a proceed 80 aspect.

The next signal is between 800 metres (2,625 feet) and 3,000 metres (9,840 feet) away. If the distance to the next signal is more than 3,000 metres, a separate free-standing distant signal is used to govern the approach to that signal.

Proceed 80, expect 40 (Kör 80, vänta kör 40) authorises the driver to pass the signal at 80 km/h or at a higher speed given by the ATC system. The next signal is displaying proceed 40, so the driver must decrease speed and approach the next signal prepared to pass it at a speed not exceeding 40 km/h (25 mph) or the speed shown on the ATC driver's display.

The next signal is between 800 metres (2,625 feet) and 3,000 metres (9,840 feet) away. If the distance to the next signal is more than 3,000 metres, a separate free-standing distant signal is used to govern the approach to that signal.

Proceed 40, short route (Kör 40, kort väg) authorises the driver to pass the signal at a maximum speed of 40 km/h (25 mph). The next signal is showing "stop" and is closer than 450 metres.

Famous quotes containing the words signals and/or main:

    The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.
    Lawrence Kutner (20th century)

    Whoever considers morality the main objective of human existence, seems to me like a person who defines the purpose of a clock as not going wrong. The first objective for a clock, is, however, that it does run; not going wrong is an additional regulative function. If not a watch’s greatest accomplishment were not going wrong, unwound watches might be the best.
    Franz Grillparzer (1791–1872)
