As part of the ongoing King’s Cross remodelling project for Network Rail, extensive improvement works have been undertaken to allow the third tunnel bore to be reinstated. The project is to provide two additional tracks on the approach to the station, ultimately resulting in more capacity and a greater flexibility for services coming in and out of King’s Cross.
