Indian Railways Approves Kavach 4.0 and Three More Works

The correct answer is the Moradabad Division of Northern Railway. Indian Railways approved Kavach Version 4.0 on the sections of this division that were still without the system, covering 712 route kilometres at a total cost of ₹170 crore. Each of the wrong options is a place that appears in the same day's sanctions, which is why the question demands care. The Samastipur Division of East Central Railway was cleared for Electronic Interlocking at 21 stations for ₹233 crore, work that in turn prepares those stations for Kavach. Adra appears as one end of a new 11 km bypass line in South Eastern Railway costing ₹272 crore. Bhavnagar appears because the Bhavnagar Para yard in Gujarat is to be remodelled for about ₹125 crore. Fix the pair that carries the answer: Moradabad, 712 route kilometres and ₹170 crore.

The correct answer is that Kavach is an indigenous Automatic Train Protection system, often shortened to ATP. The release sets out four things it does, and each of them is worth remembering separately because questions are framed on them. It helps prevent Signal Passing at Danger, a situation described in the railways by the short form SPAD. It applies the brakes by itself when required to avoid an unsafe situation. It controls the speed of a train in critical conditions. And it brings down the risk of collisions substantially. The system was developed within the country, which is why it is described as indigenous, and extending its coverage is part of a wider effort to modernise signalling and train protection across the network. The other three options describe activities of the railways that have nothing to do with Kavach.

The correct answer is the Energy, Mineral and Cement Corridor identified for Indian Railways. The bypass of 11 km, sanctioned at ₹272 crore in South Eastern Railway, will separate train paths and provide a two-way connection to a third line that is planned on the route. Its purpose is heavy industrial traffic, which is exactly what the corridor is named for. The release links it to the iron ore demand of SAIL, given as 23.40 MTPA, and to the 45 rakes a day projected by BCCL. It also gives the capacity arithmetic: the section works at 71 per cent utilisation at present, line capacity of 47.50 per cent is expected to rise to 56.45 per cent by 2028-29, and the bypass should permit additional traffic of 8.88 MTPA once complete. The other options name corridors and networks not mentioned here.

The correct answer is Electronic Interlocking at 21 stations of the Samastipur Division of East Central Railway, approved at a total cost of ₹233 crore. The work replaces existing panel interlocking with Electronic Interlocking, which is computer-based signalling in place of ageing relay-based systems, giving higher reliability, quicker fault diagnosis, easier maintenance and greater operational flexibility, besides supporting the roll-out of Kavach. The remaining options carry the other three figures of the same day and should be learnt as a set. Kavach 4.0 for the remaining 712 route kilometres of Moradabad Division cost ₹170 crore. The 11 km Adra-Joychandipahar bypass in South Eastern Railway cost ₹272 crore. The Bhavnagar Para yard remodelling in Gujarat cost about ₹125 crore. Arrange them in ascending order once and the four are easy to hold together.
