Calls for an independent investigation into the role of Transport for London (TFL) in supplying information to Croydon tram crash investigators have been made.

Assembly member Keith Prince put forward a motion claiming that TfL failed to provide key tram safety evidence following the tragic Croydon tram crash. 

The crash in November 2016 left seven people dead and more than 60 others  injured when a tram derailed at Sandilands.

And earlier this year TfL blamed human error for not immediately sharing an audit on driver fatigue with investigators of the crash.

Mr Prince proposed a motion calling on Mayor of London Sadiq Khan to open an independent investigation into why TfL failed to hand over vital information.

He said: “In reality we do not know whether it is cock up or conspiracy and that simply cannot be accepted we need a definitive answer to this and many more questions.

“We need a truly independent inquiry into this matter so it stops all the speculation around it.”

The motion was seconded by assembly member for Sutton and Croydon Steve O’Connell.

But Fiona Twycross described the motion as ‘political gameplaying’.

She said: “We know that off their own instigation TfL did an internal audit to examine the effectiveness of fatigue management processes at the managers FirstGroup.

“We know that they immediately informed the Rail Accident Investigation Branch and we know that they also made the British Transport Police, who are still carrying out an investigation, aware so family liaison officers could bring this to the attention of family and victims of the Sandilands incident.

“Of course there were always lessons to be learnt and TfL has held their hands up and admitted that this audit should have been immediately sent to investigators. That this didn’t happen was the rsult of human error.”

She added that TfL has since updated its procedures so that audits of a live investigation are automatically sent on.

The motion was backed with 10 votes in favour – Labout members abstained on the vote.

A TfL spokesperson said: “We are committed to supporting all those affected by the tragedy at Sandilands in any way we can, and our attention is focused on preventing anything like this from ever happening again.

“We have always cooperated fully with all of the investigating bodies following the tragedy at Sandilands.

"We have apologised unreservedly for the human error which meant a single report which was commissioned following a separate incident on the tram network wasn’t immediately shared with the regulators, and we rectified that error as soon as it was identified.

"The RAIB carried out a thorough investigation into Sandilands, including forming an independent view on the issue of fatigue management, and included our audit in their final investigation report.”
