Great video. Just for future reference, there is no such thing as a 'Class 82'. The numbers on LNER DVT's (eg: 82209) are vehicle/coach numbers, NOT a class identification.
there were some problems with the closure. Good was operationally it appeared two Southern Drivers per train were doing New Cross Gate to London Bridge as pilots/shuttles with a change to LO full new driver at New Cross. There were a few banners near Platform 15 where most were arriving/departing from (at a rather confusing nowdays London Bridge Station which makes "interchange to the tube" somewhat of a walk. its nearly easier to walk accross London Bridge to the District Line. There were also plenty of LO staff on the London Bridge platform and at the bottom of the escalator up to the platform - these were giving away chocolate mini-eggs. The bad part was the Replacement Bus Service New Cross Gate (Stop R) New Cross and up to Dalston Junction every 20mins didnt actually appear to stop at the indicated times at Stop R (and no service "X" was shown on windscreens. The replacement service M that ran from Surrey Quays etc onto Peckham to Clapham Junction didnt serve New Cross Gate - or stop on the roads despite passing incredibly close to New Cross Gate Sainsburys Bus Terminal - which might have been a better interchange and service up grade when the Overground or Southern is otherwise closed
