and V513 in the position leading to the right. The local point operation group 1 must be
protected from the direction of tracks 552 and 581 by preventing route setting from the
signals P552 and E581 to tracks 502, 503 or 504. The local point operation group 2
must be protected by preventing route setting from signals P551, P552 and E581.

The signalling elements inside the dashed lines
are included in the local point operation group
Figure 6.3:26 Protecting local point operation by a point and signal.
The track sections, which allow traffic from the direction of the local point operation
group while local point operation permission is given, are associated with the local point
operation group are connected to the local point operation group. The track sections
associated with the local point operation group must be limited as viewed from the
direction of the points included in the local point operation group, by
–
a derailer or a stopping device, which is not included in the local point operation
group,
–
a signal, which is displaying a ‘Stop' aspect to a train approaching from the
direction of the points included in the local point operation group,
–
a board marking the limits of shunting work,
–
a station entry signal,
–
a track section, where the track vacancy proving ends or
–
a signal providing flank protection for the local point operation group.
The shunting signal must display a monitored ‘No aspects' aspect, if the track sections
in rear and in advance are associated with the local point operation group, which has
been given local point operation permission.
In Figure 6.3:27 the points of the railway operating location are divided into three local
point operation groups. The local point operation group 1 is formed by the functional
entity of points at the left end of the railway operating location, the local point operation
group 2 is formed by the points at the right end of the railway operating location and
local point operation group 3 is formed by the point at the left end, which can be
separated into its own functional unit. When the local point operation groups 1 and 3
have local point operation permission simultaneously given, the points between the
points V511 and V513 included in the local point operation groups are included in the
local point operation permission.
