A Deep-mined Station on the Elizabeth line, London

Summary

This paper describes some of the key challenges and lessons learned in creating a deep-mined, sprayed-concrete lined station shell for London’s new Elizabeth line. Tottenham Court Road station was one of five such stations in the £14·8 billion Crossrail project to deliver a new 118 km east-west railway across the UK capital by 2019. Creation of two 240-m-long platform tunnels in a dense, urban environment required the development of unique design and construction solutions, including ground improvement and safeguarding measures to mitigate ground movement. Strong collaboration and effective technical and construction coordination across the many asset interfaces were key factors in achieving a successful outcome.
