London Underground Liverpool Street Diamond Crossover renewal

摘要

The Liverpool Street Diamond Crossover is situated approximately 50m east of the station, allowing Central line trains to enter and exit the two sidings. At over 60 years old, the track condition was in line for a full renewal. To facilitate the work, over 300m~3 of concrete were pumped from street level over 15m, down a vent shaft on Bishopsgate Road. Over 400 tonnes of rubble were removed and new track was installed to complete the project, which involved extensive collaboration between a number of stakeholders including Transport for London (TfL), Track Partnership, Broadgate Estates, the City of London Corporation, Hanson Concrete and Camfaud Concrete Pumps.
