As some of you will probably know, Tramlink have exercised their option for another 4 Variobahns, for delivery in 2015. I was thinking about it tonight, as to what might be done. Someone I know suggested that these 4 might just run on the existing route 3 between Wimbledon and New Addington. However what might be more sensible would be doubling the section of track between Phipps Bridge and Morden Road, and then extending route 4 as far as Wimbledon, to give better links towards Elmers End from Wimbledon (not to mention an easier reversal than clearing the tram out and then going into the depot and coming back). With the current space issue at Wimbledon, to run this higher frequency service, some stepping back might be required, but that shouldn't pose too much of a problem, indeed I have seen it done before. What do you think should be done though?
