well not really cancelled, as it has never actually been confirmed, more
mothballed

But I can't see it being resurrected any time soon, not if commuter numbers
are permanently on a downwards projectory.

Also "TfL will also have to further investigate driverless trains"

surely they do that as a matter of course anyway?

It has to be a long term aim, but it's a 25 year solution to TFL's funding
not one that can be implemented on a 1 year one timeframe
