First units have now been taken out of service, now that the 700s have started on the GN. 365505, 517 and 519 are at Hornsey at the moment. The plan a couple of weeks ago was 6 units (i.e. 2 x 12 cars) to be stored. A 12 car hot spare would be kept in case a 700 failed, and the other three units would be going through dilapidation repairs (replacing damaged seat cushions, misted windows, wall moquette panels, that sort of thing), but that's probably all changed by now! Even at Hornsey we don't know where the 365s will be heading once they've finished on the GN. We don't even know if we're keeping any! And this thread was the first I'd heard of the 313s heading to the coast.
