Signalling devices represent key elements of railway traffic safety systems, designed to provide clear, reliable, and safe signal indications.
Main Signals
Main light signals are installed so that the signal plate with the signal lamps is positioned perpendicular to the track.
The position of the signal plate and the signal lamps can be precisely adjusted in order to properly direct the light beam according to site conditions.
Main signals are used to issue commands allowing or prohibiting further train movement.
The minimum visibility distance is defined by the maximum permitted line speed
(e.g. for 160 km/h – at least 500 m).
The installed signal structure with foundation is designed to withstand wind speeds of up to 150 km/h without permanent displacement or deformation.
Variants:
- 2, 3, or 4 signal lamps
Standard or tunnel type
Limit Track Signal
The limit track signal is used for:
- Dividing the main track into limited route sections
- Marking the end of the main track where no main signal is installed
- Marking the end of a dead-end track (buffer stop)
It consists of a signal housing with four lamps:
- two red lamps (mounted horizontally)
- two milky white lamps (mounted diagonally from left to right)
The lamps (30 V, 15/15 W, Ø70 mm) include shades that allow precise light beam direction.
The signal is installed on a signal pole with ladder access and a standard foundation with fastening elements.
Shunting Signal
A shunting signal indicates whether shunting movement beyond the signal is permitted or prohibited.
It consists of two lamps (Ø70 mm):
- upper red lamp
- lower white lamp
The housing allows the light beam to be directed around the vertical axis up to 30% in both directions.
The signal also includes elements for measuring and regulating the current of the signal lamps.
The signal is installed on a standard concrete foundation, where the upper edge of the foundation is positioned 60 mm below the top of the rail.
Direction and Speed Indicator
These devices supplement the signalling of main signals and distant signals, providing more precise information about train direction and permitted speed.
They are installed below the signal plate on the signal pole and consist of:
- housing
- lamp panel
- up to 35 signal lamps arranged according to their function
Signal Sign 78
Signal sign No. 78 is used to give the train departure signal.
It consists of a circle of green signal lamps (12 in total) arranged in two separate electrical circuits:
- one circuit – hatched circle
- second circuit – non-hatched circle
The signal is installed below the signal plate of the departure signal or on a separate pole.
Signal Lamp – Lantern C25231–A2–A1
The signal lamp (lantern) is designed for light signalling in railway and maritime systems where long visibility distance is required.
