Safety along with efficiency is an important priority for Indian Railways. RailTel has been entrusted with the project of replacing the old mechanical signalling system with Modern Electronic Interlocking Signalling system at 26 stations of Northern Railway. Work at 10 stations have been completed and work is in progress on remaining station. This replacement will enhance the safety and operational efficiency.
The new Electronic Interlocking signalling system will enable lowering the signal and changing of tracks by click of a mouse. Earlier mechanical interlocking system was having standard 1 interlocking which have maximum 50 kmph speed. Now, with modern electronic interlocking system ,the standard of interlocking is changed to Std-II with maximum of 110 kmph. Thus, modern electronic system is not only enhancing the safety and efficiency of train traffic but also increasing the speed.
