The rulebook of 1944 introduced a more uniform system for indication of speed restrictions. In accordance with increasing speed limits, the warning distance was changed to 800 m (875 yds) on main lines.
The track behind the board is inaccessible. On the line, the board would be placed 400/800 m (440-875 yds) in advance of the inaccessible track section.
Proceed at reduced speed. Expect warning board "Stop" 400/800 m (440/875 yds) beyond this point.
Prepare to proceed at speed indicated. The speed restriction begins 400/800 m (440/875 yds) beyond this point and is not indicated further.
Proceed at speed indicated; restriction begins immediately.
This board would only be used for speed restrictions beginning at a station. The board would be placed near the switch limit board as information for trains starting from the station.
Proceed at speed indicated when entire train has passed this point.
Proceed at prescribed speed when entire train has passed this point.
The track is occupied by unremovable vehicles or otherwise inaccessible.
This board was only used in station areas.
Since 1958 the beginning point of a speed restriction is always indicated, and night illumination has been replaced by reflective boards. In recent years the warning distance has been increased to 1200 m (1310 yds) on certain lines, and the warning distance 400 m (440 yds) is not used anymore.
The track behind the board is inaccessible. On the line, the board would be placed 400/800/1200 m (440/875/1310 yds) in advance of the inaccessible track section.
Today, the board is only used in areas without track circuits. Otherwise, protection of the track is done by shorting the rails.
Proceed at reduced speed. Expect warning board "Stop" 400/800/1200 m (440/875/1310 yds) beyond this point.
Prepare to proceed at speed indicated. The speed restriction begins 400/800/1200 m (440/875/1310 yds) beyond this point.
Proceed at speed indicated.
Proceed at speed indicated when entire train has passed this point.
Proceed at prescribed speed when entire train has passed this point.
The track is occupied by unremovable vehicles or otherwise inaccessible.
This board was only used in station areas. Since 1975, warning board "Stop" is used instead.
