The London Trams Control system was originally installed in the late 1990s when the system was constructed and comprised two distinct elements: 1. The Trams Management System (TMS), installed in the depot at Therapia Lane and comprises software and hardware components responsible for taking information from equipment across the tram network and providing status and control capabilities to control room operational and maintenance staff. The TMS additionally performs a SCADA function, including software and Remote Terminal Units (RTUs) at the various traction power supply substations positioned across the network. 2. The Programmable Logic Controllers (PLCs) installed at various locations around the tram network, provide autonomous local decision making and control of aspects of the signalling and control system. Communication between these elements is provided by a distributed fibre-optic communications system. The PLCs are original equipment and have been in use since the inauguration of the network at the turn of the century. The TMS is a more recent installation having been replaced in 2014. Both parts of the control system contain elements that are becoming obsolete and nearing life expiry. TfL is therefore procuring the design, delivery and implementation of a replacement system to encompass the full control system requirements, replacing the existing TMS, RTUs and PLCs. The requirement will also cover ongoing maintenance and support services. The procurement is for award of two contracts to the same supplier, one for the design, delivery and implementation of the replacement system, and one for the ongoing maintenance and support services. The maintenance contract will commence following the implementation of the replacement system, on a minimum term of five years and an option to extend for the life of the system. The estimated 7-year contract duration entered covers the estimated duration of the system replacement (est. 2 years) and initial maintenance term (5 years), with the option to extend the maintenance services for up to a further 15 years (covering the expected system life of 20 years total). The contracting entity for this procurement will be Tramtrack Croydon Limited, which is a 100% owned subsidiary of Transport for London.

Benchmarked against retained Find a Tender procedures with CPV division 32. The category anchor is Communications equipment (32570000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.
| Comparison set | Procedures | Reported bids per procedure | Named award suppliers | Price evidence |
|---|---|---|---|---|
| Market: CPV division 32 | 1,169 | 3 median · 41.6 average (402 of 1,169 with a bid count) | 4.2 average (449 of 1,169 with named award suppliers) | Not published |
| Same buyer | 4 | Not published | Not published | Not published |

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.
Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
No planning milestones published.
No linked framework, prior procurement or reprocurement published.

"description": "The London Trams Control system was originally installed in the late 1990s when the system was constructed and comprised two distinct elements: \n1. The Trams Management System (TMS), installed in the depot at Therapia Lane and comprises software and hardware components responsible for taking information from equipment across the tram network and providing status and control capabilities to control room operational and maintenance staff. The TMS additionally performs a SCADA function, including software and Remote Terminal Units (RTUs) at the various traction power supply substations positioned across the network. \n2. The Programmable Logic Controllers (PLCs) installed at various locations around the tram network, provide autonomous local decision making and control of aspects of the signalling and control system. Communication between these elements is provided by a distributed fibre-optic communications system. \nThe PLCs are original equipment and have been in use since the inauguration of the network at the turn of the century. The TMS is a more recent installation having been replaced in 2014. \nBoth parts of the control system contain elements that are becoming obsolete and nearing life expiry. \nTfL is therefore planning to procure the design, delivery and implementation of a replacement system to encompass the full control system requirements, replacing the existing TMS, RTUs and PLCs. The requirement will also cover ongoing maintenance and support services.\nThe procurement is for award of two contracts to the same supplier, one for the design, delivery and implementation of the replacement system, and one for the ongoing maintenance and support services. The maintenance contract will commence following the implementation of the replacement system, on a minimum term of five years and an option to extend for the life of the system. \nThe estimated 7-year contract duration entered covers the estimated duration of the system replacement (est. 2 years) and initial maintenance term (5 years), with the option to extend the maintenance services for up to a further 15 years (covering the expected system life of 20 years total).\nThe contracting entity for this procurement will be Tramtrack Croydon Limited, which is a 100% owned subsidiary of Transport for London.",

"description": "TfL issued a 'F01: Prior information notice' on Find a Tender Service on 19th January 2024. This was published under the Utilities Contract Regulation 2016. \nInterested parties responding to this notice were issued a Market Sounding Questionnaire (MSQ) with a deadline for completion by 13th March 2024 for feedback to be considered. \nThe scope of the MSQ covered: \nInterest \nCapability and experience \nNeed for sub-contracting \nExisting software/hardware availability \nContracting approach \nEngineering challenges, technical and commercial risk \nMaintenance and support \nInnovation \nSessions were subsequently held with respondees assessed as having the capability and experience for the scope of works based on their MSQ responses. Each session further explored the responses to the MSQ questions. \nThe market sounding confirmed adequate interest and capability to progress this procurement. \nThe scope of this procurement has not changed as a result of the engagement, though clarity is now provided that the procurement will encompass the requirement for ongoing maintenance and support services. \nIn addition, it is confirmed that the design, delivery and installation of the replacement system will be on a fixed price basis. \nTfL is not seeking further engagement prior to the Tender Notice being issued, but requests interested suppliers take note of revised procurement timeframes, with the Tender Notice now planned for publication in July 2025."
