Английская Википедия:Finnish railway signalling
The signalling system used on the railway network in Finland comprises color-light signals and fixed signs, used together with the Automatic Train Control system ATP-VR/RHK (an EBICAB 900 system better known as JKV, Шаблон:Lang-fi).
Main signals
The main signal can have any of the following aspects:
Aspect | Meaning | Old system (Helsinki area) | |
---|---|---|---|
Файл:Opaste seis.svg | Stop | The signal must not be passed. | Файл:Opastin vanha3 seis.svg |
Файл:Opaste aja.svg | Proceed | The signal may be passed with the maximum allowed speed. | Файл:Opastin vanha3 aja.svg |
Файл:Opaste aja sn35.svg | Proceed 35 | The signal may be passed and the maximum speed of Шаблон:Convert is in effect from the next switch, which may lead to the diverging route. An ATC cab display may authorize a higher speed, typically Шаблон:Convert. The speed is in effect until the next main signal or after leaving the station area. The route may also lead to an occupied track section, but only if the driver has received a preliminary announcement. | Файл:Opastin vanha3 aja Sn35.svg |
If a main signal doesn't protect any switches or the speed restriction on a diverging route is the same as straight route, the signal doesn't need to show the Proceed 35 aspect and therefore the yellow bottom light may be absent. The two lamp version of the old system has the lights reversed, i.e. red at the top and green at the bottom.
Distant signals
The distant signal is located at least Шаблон:Convert 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) | |
---|---|---|---|
Файл:Opaste odota seis.svg | 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. | Файл:Hel distant expect-stop.png |
Файл:Opaste odota aja sn35.svg | Expect 35 | The next main signal shows the Proceed 35 aspect. | Файл:Opastin vanha odota aja.svg |
Файл:Opaste odota aja.svg | Expect Proceed | The next signal shows the aspect Proceed. | Файл:Opastin vanha odota aja.svg |
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.
Block signals
A block signal can show any of the following three aspects:
Aspect | Meaning | |
---|---|---|
Файл:Suojastusopaste seis.svg | Stop | The signal must not be passed. |
Файл:Suojastusopaste aja varovasti.svg | Proceed, expect stop | The signal may be passed. The next main or block signal is showing a Stop aspect. |
Файл:Suojastusopaste aja.svg | Proceed | The next main or block signal is showing a permitting aspect. The following two blocks are not occupied. |
Block signals are being replaced by combinations of main and distant signals, and no new block signals will be installed.
Dwarf signals
A dwarf signal is used for controlling shunting movements. It can have any of the following aspects:
Aspect | Meaning | |
---|---|---|
Файл:Raideopaste seis.svg | Stop | The signal must not be passed. |
Файл:Raideopaste aja varovasti.svg | Proceed with caution | The signal may be passed, but the track may be occupied by cars or another train. |
Файл:Raideopaste paikallisluvat.svg | Signal cancelled | The signal may only be passed by the unit that has a permission to do shunting or track work. |
A dwarf signal may also be placed in conjunction with a main signal. If the main signal shows any other aspect than Stop, the dwarf signal shows the Proceed with caution aspect.
Bridge signals
Bridge signals are small signals used to display the orientation of a moveable bridge. They can have any of the following aspects:
Aspect | Meaning | |
---|---|---|
Файл:Siltaopaste seis.svg | Stop | The bridge is open and the signal must not be passed. |
Файл:Siltaopastin Ei opasteita.svg | Signal cancelled | The bridge is closed and the signal may be passed. |
Файл:Siltaopaste aja.svg | Proceed | The bridge is closed and the signal may be passed. This signal is no longer used. |
Repeaters
Repeaters are sometimes used to repeat the aspect of the main signal in the Helsinki area in places where the main signal is not clearly visible.
Aspect | Meaning |
---|---|
Файл:Kertaaja seis.svg | The main signal is showing the Stop aspect. |
Файл:Kertaaja aja.svg | The main signal is showing some Proceed aspect. The train can be moved to the main signal. |
Helsinki Metro
The Helsinki Metro signals differ from those used by the railways.
Main signals
Some aspects may be shown using a signal with only three lights, pictured on the right.
Aspect | Meaning | |
---|---|---|
Файл:Helsinki Metro signal Po 0.svg | Stop | The signal must not be passed. Forced stopping magnet is active. |
Файл:Helsinki Metro signal Po 1.svg | Proceed | The signal may be passed with the maximum allowed speed. |
Файл:Helsinki Metro signal Po 2.svg | Proceed 35 | The signal may be passed. Speed limit after the signal is Шаблон:Convert. The train may enter a diverging track through a switch. |
Файл:Helsinki Metro signal Po 3.svg | Coupling | The signal may be passed, but the track may be occupied or is an ending track. Speed limit after the signal is Шаблон:Convert. |
Файл:Helsinki Metro signal Pk 0.svg | Exception | Drive at driver's responsibility. Forced stopping magnet is active. Speed limit after the signal is Шаблон:Convert. |
Distant signals
Aspect | Meaning | |
Файл:Helsinki Metro signal Eo 0.svg | Expect other than Proceed | The next main signal is showing one of the aspects Stop, Proceed 35 or Coupling. |
Файл:Helsinki Metro signal Eo 1.svg | Expect Proceed | The next main signal is showing the Proceed aspect. |
