Manchester Metrolink -Tram Safety Improvement Programme (TSIP)

TfGM is seeking to procure a single contract to deliver a Tram Safety Improvement System consisting of a Driver Vigilance Device (DVD) and a Tram Overspeed Prevention System (TOPS). This could be one system that is able to deliver both functions or two separate systems. The contract itself will cover design, installation, testing and commissioning, with the provision (at TfGM's discretion) for servicing and maintenance. The requirements are driven by an RAIB recommendations report with the requirements to be addressed by all UK Tram / Light Rail Networks. The purpose of the TOPS is to satisfy the requirements of RAIB recommendation 3, extract provided below: “The intent of this recommendation is to prevent serious accidents due to excessive speed at high risk locations on tramways. These locations are likely to include all locations where a substantial speed reduction is required by trams approaching at relatively high speed…” The purpose of the DVD is to satisfy the requirements of RAIB recommendation 4, extract provided below: “The intent of this recommendation is to reduce the likelihood of serious accidents due to tram drivers becoming inattentive because of fatigue or other effects. Existing tram systems relying on drivers applying forces to driving controls (driver safety devices) do not necessarily detect an inattentive driver.
