In a week of big stories, I still find this the most shocking. The actual emails have surfaced in which TfL's safety audit team discuss watering down a report on Croydon Tram to 'placate' First Group, who ran it. And still no investigation by @SadiqKhan. https://www.cityam.com/exclusive-tfl-officials-watered-down-croydon-tram-safety-audit-to-placate-first-group/

After discussing TOL's lack of cooperation with his boss, the audit manager writes to his team : "Firstly I will apologise for what we are about to do... remove the front page [and] audit conclusion, this will placate TOL... no doubt we should discuss rather than send emails."

We also know TOL/First Group had been criticised over fatigue management on the Croydon Tram in 2014, and that TfL knew; in 2016 TfL covered up a safety audit being undertaken at the time of the Sandilands crash; and TfL failed to send the 2017 audit to police and investigators.

. @MayorofLondon, Chair of TfL, has been told to launch an independent investigation by the @LondonAssembly, @GMB_union and numerous campaigners and public figures. But he keeps hiding behind a whitewash report 'choreographed' by the same managers who presided over all this. Why?

This week he was again grilled by @KeithPrinceAM. All he could do was read the same script he's been told multiple times doesn't answer questions. It's so disrespectful to the families of the 7 who died at Sandilands! AM @SteveO_Connell agreed: there has to be an investigation.

I asked to stay on the board of TfL and serve as chair of the Safety Panel under @SadiqKhan because I wanted to help fix TfL Surface Transport's "institutionally unsafe". culture - and because he promised to govern with transparency. I could not be more let down. So frustrating.
