To make use of the BS&WR's existing permission for the line to Paddington, Edgware Road station was to be provided with a second pair of platforms to enable the operation of a shuttle service between Paddington and Edgware Road.
For at benytte BS&WR's eksisterende tilladelse for banen til Paddington blev der bygget et ekstra set perroner på Edgware Road Station for at muliggøre en shuttle service mellem Paddington og Edgware Road.
