UK: Transport for London is to call tenders in July for a contract to replace the control system on the Croydon tram network.
The existing London Trams control system has two parts. The current Tram Management System at Therapia Lane depot was deployed in 2014, while programmable logic controllers dating from the opening of the network in 2000 are installed at various locations to provide autonomous local decision making and control.
Both parts of the system contain elements that are nearing life expiry.
TfL plans to award one supplier two contracts. An initial two-year fixed-price contract would cover the design and implementation of a replacement system covering all the control requirements. This would be followed by an ongoing maintenance and support contract running for five years from January 2027, with an option to extend to December 2048 to cover the expected 20-year life of the technology.
Separately, TfL plans to award a contract to design and build a stores building and an additional stabling road for three trams.
