Investigators looking into the fatal Croydon tram derailment have outlined a series of draft safety recommendations.
The Rail Accident Investigation Branch revealed it had written to bodies including Transport for London to set out the areas its key recommendations were expected to cover.
It comes as part of the ongoing probe into the tragic incident in November 2016, that saw seven people die after a tram overturned on a bend.
The RAIB earlier this year said the tram was travelling at approximately 73km/h as it entered the curve, which had a maximum permitted speed of 20km/h.
There was no evidence of track defects or obstructions, this second interim report said.
The RAIB today said key recommendation areas were likely to be:
- Provision of active tram protection to prevent serious accidents due to excessive speed at high risk locations
- Research into active means of detecting the attention state of drivers and intervening in the event of inattention
- Improved containment of passengers by tram windows and doors
- Setting up of an industry body to facilitate more effective cooperation between UK tramway owners and operators on matters related to safety performance and the development of common standards
London transport commissioner Mike Brown said a number of additional safety measures had been introduced to the tram network since the incident, including additional speed restrictions, enhanced speed monitoring, new signage for drivers and an upgrade of the CCTV recording system.
“An in-cab vigilance system is being trialled and should be fitted to all trams by the autumn,” he added. “Any sign of driver distraction or fatigue will result in the driver being alerted immediately. Work on an alert system for monitoring and managing tram speed is underway.
“We continue to work with the wider tram industry on these improvements and will consider any further measures that could be introduced to improve safety. We also continue to work with the RAIB and will take on board all recommendations from this and the other investigations that are underway.”
