- Dutch railway signalling
-
The current Dutch railway signalling system operated by ProRail has been in effect since 1954 on the Dutch Railways network
It was designed to be one of the simplest in Europe and is integrated to the ATB, the system of cab signalling widespread on the Dutch network.
Dutch trains normally use the right-hand track and the signals are placed at the right of the track; in sections also equipped to run on the left track, the signals are placed on the left.

Light Signals
Below are common forms:
- raised (hooggeplaatst) signal, can be used anywhere;
- ground (laaggeplaatst) or dwarf (dwergsein) signal, used in areas where speeds do not exceed 40 km/h, (do not have numeric display)
- warning (voorsein) signal.
Their aspects are categorized according to the colour. (There is never more than one colour at a time):
Green Aspect
- Green: proceed (in the case of a dwarf signal, speed restricted to 40 km/h;
- Flashing Green: proceed speed restricted, 40 km/h;
- Flashing green with figure: proceed speed restricted, 10× the displayed digit in km/h
Yellow Aspect
- Yellow : reduce speed to less than 40 km/h (the next signal is at ‘stop’ aspect);
- Yellow with digit displayed: proceed speed restricted, 10× the displayed digit in km/h);
- Yellow with flashing digit displayed: reduce speed to (10× the displayed digit in km/h), and keep the brake if the next signal still shows a yellow aspect (used to signal short sections);
- Flashing yellow: proceed at sight.
Red Aspect
- Red : stop in front of the signal;
- Flashing Red: stop in front of the signal (used for work trains).
Speed displays
Reference speed of the line (10x the displayed digit in km/h) allows the speed increase to the indicated value, if absent: 125 km / h) when the rear of the train has passed the display. 
Speed restriction: requires to reduce speed to the indicated value (10x the displayed digit in km/h). 
Speed restriction to (10x the displayed digit in km/h). It indicates both the start of a the speed restricted zone (indicated by the yellow triangle on edge) or the permission to accelerate to a speed lower than the reference speed of the line (in this case after the rear of the train has passed the sign).
