They're not going to start employing conductors again, because they're too expensive and with Oyster there's less need for them. Nor could a bus with an open platform be introduced now, so what's the point of a new-generation Routemaster? Besides, the original one was a product of London Transport in the 1950s, an organisation that did everything in-house and was prepared to spend millions to design a purpose-built London bus to serve for several decades. Tfl doesn't work that way, and anyway, there are far more and more satisfactory double-deckers available to buy straight from the manufacturer now than there were in the 1950s. IMO a 'new Routemaster' is a nice idea and it was probably a good election pitch, but it's never going to happen. Nor could the original ones ever be brought back, since they'll soon be illegal under the DDA, and most of them have been sold off anyway. And tbh, much as the original was an icon, its time had passed. It'd be nice to see some more running on 'heritage routes,' but it's not coming back into everyday use.
