SIGNAL AND TELECOMMUNICATION DEPARTMENT FOR SPEED, SAFETY,

RELIABILITY AND PUNCHULITY

Migration of Technology from mechanical lever operated semaphore Signal & overhead

communication to panel interlocking with LED signal & OFC based communication was really

fast in Solapur divn. At Solapur we always look forward to adopt state of the art advance

technology for safe & reliable operation of train.

There have been considerable increase of DESU, still significant reduction in Signalling failure

could be achieved by adopting Remote, Online Conditional Monitoring of Signalling equipment

and continuous knowledge up gradation of maintainer (Mechanical to relay based color light

Signalling, Overhead to OFC communication). Out motto is to reduce the maintenance efforts

while maintaining the reliability

To keep pace with change in technology a Divisional training Center have also been set up

with in-house recourses

damage to Signalling & Telecom equipment all installations are provided with B & C

Class surge protection devices and Maintenances Free Earth for the power equipments.

Most of the stations in KWV-LUR section are unmanned; to reduce maintenance efforts

while maintaining the reliability Exothermic welding for rail joints & track lead wire

connection has been provided.

Magnetic boom Lock has been provided on 34 Nos of LC as an additional safety measure

to ensure positive locking of the LC gate in closed position.

Remote Power supply & Battery Monitoring System:

Power Supply: Power supply is the heart of Signalling

System any defect/failure of Power supply leads to

complete shutdown of Signalling System. Accordingly

special emphasis has been given to Power supply. IPS has

been provided at all PI stations (71) (excluding major

RRI) including 12 interlocked gates to prevent the

blanking of the signal.

To charge of batteries during long power cut 175 Diesel

Generator Set has been provided at stations & Interlocked

LC gates.

Reliable working of IPS and battery is essential

for functioning of Signalling equipment. GIU

based Remote Power Supply monitoring

(Integrated Power Supply) system in Daund-

Manmad section & Remote predictive battery

monitoring system for Padhegaon station have

been commissioned for first time on Indian

Railway. This will ensure round the clock

monitoring of IPS & individual battery from

Centralized Control. This will also enable to

monitor the running of DG & will ensure saving

in fuel consumption.

Solar Charging of IPS battery

Telecommunication

Train Control Communication: Omnibus control circuits at each station provided on OFC in B

& D route and on quad cable in E-Route. 6-Quad cable and 4-Quad Cable have been provided

for the Block/ Gate Working and emergency communication. All stations on the B-Route are

provided with a Hot line communications with the adjacent station on OFC network.

The short-haul STM1 equipment is provided at every station (53 stations) in B & D-route. The

STM1 network is protected by long-haul STM4 (7 stations) self healing ring network.

VHF Communication: 5 watts walkie-talkies have been provided to Driver, Guard along with

25 watts VHF set at stations to establish communication between moving train & station staff. In

addition 5 watt Walki Talki sets have also been provided to staff of maintenance dept.
