Finnish Railway Signalling - Distant Signals

Distant Signals

The distant signal is located at least 1,200 metres (3,900 ft) before the main signal. It may also be located in the same post with a main signal, below it. In this combined arrangement, whenever the main signal shows a stop aspect, the distant signal doesn't show any aspect at all.

A distant signal can have any of the following aspects:

Aspect Meaning Old system (Helsinki area)
Expect Stop The next signal shows the Stop aspect. The train route may also be set to a track section without further signals, e.g. toward unsignalled line or a buffer stop.
Expect 35 The next main signal shows the Proceed 35 aspect.
Expect Proceed The next signal shows the aspect Proceed.

Note: Although the green light of the old system distant signal used in Helsinki area is named Expect Proceed aspect, the next main signal may in fact be showing the Proceed 35 aspect. Therefore the driver has to act as if the signal aspect is indeed Expect 35.

Famous quotes containing the words distant and/or signals:

    The settlement of America had its origins in the unsettlement of Europe. America came into existence when the European was already so distant from the ancient ideas and ways of his birthplace that the whole span of the Atlantic did not widen the gulf.
    Lewis Mumford (1895–1990)

    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)
