The work in the remaining 12 yards is targeted for completion by February 2027. Renewal of 4,000 casual sleepers has also been done on the track. Similarly, switch expansion joints (SEJ) have been renewed completely in 16 yards, and the work in the remaining 12 yards will be completed by February 2027. Rail structure interaction (RSI) studies were also carried out on two bridges, after which long welded rail (LWR) was extended. This helped eliminate free joints.
