Rode 319.008 and 447 today which will be gonners by next weekend. Guessing Cricklewood will be full of stored 319's once the resident 700s start earning their keep
I guess they'll be towed off to Long Marston pretty rapidly. Theres a path for Monday from Hornsey to Long Marston. Not sure if that's 319s but could be as theres a few Cricklewood to Hornseys in the system before then but they look more like 700 test paths to be honest.
