The project itself has been going since 2010/11, and was featured in a rail magazine a few years back, but little news lately. It is in essence a return to a stub type point, though in the full implementation the stubs have an interlocking shape, and the actuation is by way of cam to lift and move the entrance track. London Underground was supposed to be the first partner, installing and testing the first working example.
Does anyone have any more information or news on the subject? Very interested to find out how its progressing and what those with first hand experience make of its chances.
