Can someone familiar with ops at Kentish Town explain the current platform
usage?

Are there two platforms normally used for stoppers and two for through
trains and diversions into St Pancras? AIUI there are junctions both north
and south of the station so trains to St Pancras LL can use either route?

I was wondering how they will deal with the trains that terminate at Kentish
Town, (vice Blackfriars under KO0). For instance would the signalling allow
all through trains to use the outer platforms, leaving the middle platforms
(2 and 3) for trains terminating and reversing?

Will the Kentish Town platforms remain limited to 8 car under the full
Thameslink improvements - I see there is a fair amount of lengthening now
happening at stations northwards to Elstree...
