Speed execution signals

An execution of a speed limitation is given with a number under the signal.

Picture 31.4: The signal can display 4 or 6

Speed announcement signals

The speed limitation is announced with green yellow horizontal.The signal will carry a white triangle with in black letters, the minimum restrictive speed in the next junction. If the minimum speed limitations is 40km/h the sign is not shown. In this case the trainengineer must expect a speed of 40km/h

Picture 31.5: Because this signal doesn't have a white triangle the next signal must be expected to show 40km/h.


Picture 31.6: Announcement signal of junction Hever. The next signal can give a speed execution order. The execution order will be 100km/h. Recognize the white triangle.

Speed signalling of divergent traffic

The driver must enter the divergent track with 40 km/h en keep this speed till he is again at the main line. In the junction the speed is already reduced and the exit signal mustn't repeat this limitation.


If the divergent route and the main line are having the same reference speed, the speed limitations will be announce with speedboards

If the speed exection is less than 40km/h, it must be indicated.
In the station Lobbes (lign 130) the entry speed is less than 20km/h

The speed limit is assumed to be 40km/h.
The exit signal in station Franiere indicate an exit speed of 20km/h. The speed limitations are announced with speedboards.

The restrictive speed depends on the turn-out through switches.
One main signal can indicate multiple speed indications. The announment signal will cary a white triangle with the value of the LOWEST execution speed. However if the lowest speed is 40km/h the triagle isn't placed.

The announcement signal can give the more information aout the speedrestriction. The value is shown above the signal.  The lowest speed is placed in a rectangle.

In Liedekerke a line branches off with a switch of 90km/k. The intersection is at 40km/h (A difference of more than 40km/h). See example below.
Left: direction Brussels   right: direction Gent   up: direction Denderleeuw

Picture 31.7: Entry signal Diegem direction Leuven.

The resticted zone will be kept as short as possible
To reduce the zone, a speed indicator is placed after the junction

In the NZV, selectivity speed signs are illuminated in the junctions to speed up the trafic

The train engineer must keep his speed at 60km/h during the passage.
When the sellective speed sign is illuminated , the train engineer can resume his speed.
