In a leader tonight the Evening Standard summed it up nicely:
“In the context of what a scheme like the Thameslink expansion could achieve for commuters, the Mayor’s persistence with his pet scheme for a tram in west London looks increasingly inexplicable. The tram would displace traffic onto residential roads and a majority of those living locally object to the plan – following the election of three councils on a platform of opposition to the scheme. This is no way to go about improving public transport.”
You could say the same thing about Crossrail as well.
