SADIQ Khan sparked fury today as he splurged £6m of taxpayer's cash wokifying the London overground.
The Mayor of London was accused of "virtue signalling nonsense" as he announced new names and colours for six lines.
They include the "Liberty Line", the "Windrush Line" and the "Suffragette Line".
TfL insisted the changes would make it easier for passengers to identify different routes.
Previously they were just collectively referred to as the "ginger line".

Mr Khan lauded the move as "a hugely exciting moment, transforming how we think about London’s transport network".
He said: "Giving each of the Overground lines distinct colours and identities will make it simpler and easier for passengers to get around.
"In re-imagining London’s tube map, we are also honouring and celebrating different parts of London’s unique local history and culture."
But Tory mayoral candidate Susan Hall blasted the renaming as a waste of money.
She said: "The Central line is in a terrible state, TfL is wasting money left, right and centre, crime on the Tube is soaring, and Sadiq Khan is ignoring all of this to focus on his own PR.
"I will listen to Londoners, fix the problems with TfL and get a grip of crime."
Former cabinet minister Lord Frost said: "The London tradition is that public transport lines are given a name either with a royal connection or one related to the line's geography.
"Giving them political names is, whether one agrees with the politics or not, a break with that tradition.
"It's part of the general forced politicisation of so many aspects of our daily life nowadays. Of course one would expect nothing better from Sadiq Khan and his appallingly poor management of TfL and of London."
