For a part of London so near to the centre, it is crazy how inaccessible this area is. If I had to find something critical to say, it would be that the route is not ambitious enough—could it not head further West to join up with somewhere on the District line?
When I replied to the consultation survey, my own suggestion was that the line should extend beyond Battersea and terminate at (the relatively near-by) Clapham Junction which, despite being the busiest rail station in Europe (by number of trains), has no Tube station.
The driver—and, indeed, source of much of the money—seems to be the redevelopment of Battersea Power Station, which looks to be (if it actually happens) a rather exciting development of a sadly neglected landmark.
Let us see how it goes...
