All of the 8 car trains in the RUS are coming from Elephant, and I'm
assuming there are lots of stations in that direction that only have 8
car platforms. Since there isn't capacity at Blackfriars to not run at
least some of these 8 car trains through the Thameslink core, that
means even if Kentish Town were extended, Thameslink would still have
8 car trains.
