REL completes Electronic Interlocking at all three stations of Delhi Division

RailTel Enterprises Ltd. (REL) has commissioned an Electronic Interlocking signalling system at Kalayat and Kaithal station of Delhi Division, Northern Railway. With this, the old mechanical signalling system at these two stations has been replaced by state-of-the-art modern signalling.  Electronic Interlocking had earlier been commissioned at Pehowa Road Station. Earlier these stations were having mechanical signalling systems and were using lever frames for Signal interlocking.

The new Electronic Interlocking signalling system will now enable lowering the signal and changing of tracks with a click of a mouse. The changing of the mechanical interlocking system with modern electronics interlocking system will enhance safety and operational efficiency. 

Earlier mechanical interlocking systems was having standard 1 interlocking which has a maximum of 50 mph speed. Now, the modern electronic interlocking system will have a maximum speed of 100 kmph. Thus, the modern electronic system is not only enhancing the safety and efficiency of train traffic but also increasing the speed.

The clearance of block section i.e. assurance of complete arrival of the train is being provided with the latest system of Digital axle counters. Operation of 05 nos of level crossing gates has also been changed from mechanical to electrical type which further increases the efficiency of level crossing closing and opening. The train handling capacity of the yard has been increased by allowing simultaneous reception & dispatch of the trains. The length of berthing lines i.e CSR has been increased hence full Goods train can be berthed which increases the holding capacity of berthing tracks.

To improve the Railway signalling system, Northern Railway has entrusted RailTel Enterprises Ltd.(REL) to upgrade the manual signalling system of 26 stations of Northern Railway. 

Commenting on the development, Puneet Chawla, Chairman/REL, said, “These 3 stations have been provided with signalling gears like signals, track circuit, point machine, batteries, earthing surge protection devices etc as per latest technology to standard 2R interlocking system making train operation safer, faster and more efficient. RailTel is fully geared to complete the project for modernizing signalling system at remaining 23 stations.”
