Wimbledon Line Enhancement Programme
Project at a glance:
The design and build of a new tram platform and track at two areas of Wimbledon Station
Remodelling of the area
Installation of track and overhead line equipment
Project resulted in frequency of trams between Wimbledon and Croydon rising from eight to 12 per hour, boosting capacity by 50%
Cleshar was appointed as principal contractor to carry out two packages of works at Wimbledon Station as part of London Tramlink’s Wimbledon Line Enhancement Programme to increase service capacity and ease passenger congestion.
The first package was the design and build of a new platform (platform 10), including track formation and installation. We were required to remodel the area to build the additional tram platform at the station, installing track and associated overhead line equipment to increase the tram area from 90 metres to 190 metres. Works also included canopy apron steelwork alterations, repair and decoration.
The second package involved the design, build and installation of a new track formation at the Beddington Lane to Mitcham Junction section. This included site clearance, formation dig, full track and overhead line equipment installation for a second, 750m track section to provide a twin track arrangement in place of the single line section.
Works included the demolition of existing tram tracks and substrate, which was formed of a reinforced concrete. However, demolition works were constrained as the site was confined with only one access and egress point, while noise restrictions were also imposed by the local authority.
In order to overcome this, we came up with a concrete-bursting solution, which involved drilling holes in specific locations and using expandable hydraulic equipment to break out the concrete with minimal noise and dust.
