An additional ticket hall has been built on the south side of Cowcross Street providing access to the Thameslink platforms, which have been extended southwards underneath this building, allowing the station to handle 240 m (12-carriage) trains.
En yderligere billethal vil blive bygget på sydsiden af Cowcross Street, der giver adgang til Thameslink-sporene, der vil blive forlænget mod syd under denne bygning, der gør stationen i stand til at håndtere tog på 240 m (12 vogne).
