.
The shunting signal must be positioned at least 5m distance from the fouling
sign point of a route point, which is trailing and is located in advance of the
shunting signal, if the shunting signal may not act as the main route exit signal
(figure 6.4:46).

The shunting signal must be positioned at least 5m distance from the front joint
of a trap point, which is in advance of the shunting signal (figure 6.4:47).
The shunting signal must be positioned at least 10m distance from the front joint
of a route point, which is a short facing point in advance of the shunting signal
(figure 6.4:47).
The shunting signal must be positioned at least 35m distance from the front joint
of a route point, which is a long facing point in advance of the shunting signal
(figure 6.4:47).

A track section must be positioned as the main signal in respect to a neutral
section when the neutral section is located in rear of the shunting signal.
