14.1.7 Interlocked Level Crossing Gates – Outside Station Limits

(a) On sections provided with two aspect Signaling,

(i) A Stop Signal at 400 meters from the gate shall be provided.

(ii) Where the section is provided with separate Warner signal, such a
Warner signal shall be provided at a distance of not less than 1.2 km
from the Gate Stop Signal.

(b) On Sections provided with multiple aspect signalling,

(i) The Gate Stop Signal shall be located at not less than 180 meters in
rear of the gate.

Note: Existing LC gates at 120 meters in automatic signalling/Suburban sections
may continue

(ii) In Single Distant territory, the Distant Signal shall be located, at not less
than one kilometer in rear of the Gate Signal.

(iii) In Double Distant territory, Gate Distant signal shall be located, at not
less than 2 kilometers in rear of the Gate signal and Gate Inner Distant
Signal shall be located, at not less than one kilometer in rear of the
Gate Signal.

(c) The Gate Stop Signal shall be provided with 'G' marker except where
prohibited under special instructions.

The 'G' marker shall consist of letter 'G' in black on yellow circular disc. The
instructions in Chapter 20, Section 1 shall apply to signals protecting Level
Crossing Gates in Automatic Signalling Block territory.

(d) Approach locking shall be provided, which shall be effective from a
distance not less than the Emergency braking distance of the trains running
on the section at the maximum permissible speed.

Where there are no track circuits in the rear of the Gate stop signal or the
total length of such track circuits in rear of the Gate stop signal is less than
the Emergency braking distance, Dead approach locking with delay as per
para No. 21.1.21 (Table-1) shall be provided.

14.1.8 Interlocked Level Crossing Gates within Station Limits

(a) Where interlocked level crossings within station limits are operated from a
place other than the place of operation of the signal protecting the gate,
arrangements of interlocking should be such that the last operation before
taking off the signal should be, the closing of the gate and the first
operation after the train has cleared the level crossing and the signal has
been put back to 'ON' position, should be the opening of the gate by the
Gateman.
