CHAPTER 1

AUTOMATIC SIGNALLING 1.1

INTRODUCTION

Automatic block working is a system of train working in which movement of the train is controlled by the automatic stop signal. These signals are operated automatically by the passage of trains in to through and out of the automatic signalling sections. 1.2

FEATURES

Automatic block system    

The line shall be provided with continuous track circuiting or axle counters. Block section is divided into various smallsignalling sections. Each signalling section is governed by an Automatic stop signal. Each signalling section is further divided into berthing and overlap track circuit.

ADVANTAGES



Line capacity increases.



Less dependence on human agencies.



Automatic stop signal can be passed at `ON' position as per General Rule 9.02 , after stopping one minute by day and two minutes by night.

1.4

Automatic stop signal



Automatic stop signals are multiple Aspect colour light signals.( 3Aspect/ 4 Aspect stop signals)



Aspect of Automatic stop signal are controlled by the movement of train. Letter ‘A’ in black on white circular disc

 Numbering

of signals -Normally odd nos. for up direction and even nos. for down direction.  Automatic

stop signal is provided with `A' marker.

Semi Automatic Stop Signal 

Semi Automatic stop signal can work as a manual stop signal/ Automatic stop signal.



Semi Automatic signal is provided with illuminated ‘A’ sign.



Illuminated 'A' sign will lit when signal is working as Automatic stop signal.



Illuminated ‘A’ sign will not lit when signal is working as a manual stop signal.





Controlled by king lever/ knob/ switch.

Cascading arrangement- When a colour light signal is showing a particular aspect and its lamp of that aspect fuses then signal becomes blank. To avoid this condition, cascading or cutting in arrangement in the lamp controlling circuit is provided in such a way that if a lamp fuses the signal can be restored to next restrictive aspect. Example. If green lamp fuses (when signal is displaying clear aspect), then the more restrictive yellow aspect can

be lit or if yellow lamp fuses (when signal is displaying caution aspect) then red aspect can be lit. Red lamp protection: It is provided to avoid the passing of train in no light condition of a signal. In this case the rear signal will show ON aspect, when signal ahead is showing no light.



1.5

LEVEL CROSSING GATE IN AUTOMATIC SIGNALLING SECTION : LEVEL CROSSING GATE: In Automatic signalling area, the signal controlling movement over LC gate are semi-automatic signals. Semi Automatic gate signal will be in "ON" position, when gate is open for road traffic. Level Crossing Gate signal (when no point in the route)



Yellow circular disc with ‘G’ letter in black and illuminated ‘A’ letter against black background are provided.

Illuminated “A” sign of the SemiAutomatic gate signal will lit when the level crossing gate is closed against the road traffic and signal is working as an Automatic stop signal. Letter ‘G’ in black on yellow circular disc

Level Crossing Gate signal (when points are in the route)  Illuminated ‘A’ and ‘AG’ sign are provided on gate signal.. 



1.6

Illuminated “A” sign will lit when level crossing is closed against road traffic and points in the route are correctly set and locked and signal is working as an Automatic stop signal. Illuminated ‘AG’ sign will lit when points in the route are correctly set and locked and LC gate is defective and signal is working as an Automatic stop signal.

DO’S and DON’TS

3.2.1

DO’s

36



As far as possible bulb must be replaced during morning period since mostly bulb fuse during first 5 hours.



Check due date of overhauling of track relay. if due, it should be replaced timely.



Apply glue epoxy on the rail and fish plate of joints to avoid shorting due to iron fillings and iron powder.



Check time delay circuit is working properly.



Always work carefully as train traffic is on higher side in automatic signalling territory.

3.2.2

37

DON’TS



Forget to take the no load current of signal transformer.



Forget to close and lock the back cover after completion of work.



Discharged Battery excessively.



Add impure distilled water and acid in the batteries.



Bypass the regulating resistance of track circuit at any time.



Disturb the antilittering arrangement of track relay.



Forget to give disconnection memo to on duty ASM/CASM at for time of attending failure.



Adjust the track circuit beyond the limit of track circuit parameters.



Commence maintenance work of point without telecommunication with ASM/CASM.



Try to replace any part of the point machine or associated wiring without proper disconnection notice.
