Baker Street station is one of the oldest Underground stations in the world. It opened on 10 January 1863 as part of the Metropolitan Railway, the first underground railway in the world. Today it serves 5 lines on 10 platforms. We are now going to the oldest part of the station. These are the original platforms of the Metropolitan Railway, which have been beautifully restored to their original appearance in the 1980s. The original Metropolitan Railway ran from Paddington to Farringdon, using trains hauled by steam locomotives. Today, modern S7 stock trains use the platforms. Located between Edgware Road and Great Portland Street, these platforms today serve the Circle and Hammersmith & City lines. Today’s Metropolitan line uses different platforms, and the tracks branch off this line just behind us. The underground railway and the stations have been constructed via the cut-and-cover method. This means we are just beneath the surface. The departing train is a Hammersmith & City line service to Barking. We are now on the opposite platform with services to Paddington and Hammersmith. These modern trains make for a nice contrast with the old station architecture. We are now headed to the Metropolitan line platforms. At the south end, the line branches off the Circle and Hammersmith & City line routes. Some Metropolitan line trains use this route for services towards Aldgate, but due to capacity constraints, some Metropolitan line trains also terminate at Baker Street. This service came from Aldgate and will terminate at Uxbridge in the far west. The departure boards show all calling points, which is quite unusual for the London Underground. But the Metropolitan line has a rather complicated service pattern with many branches and also fast and semi-fast services, which skip some stations. We are still on the same platform but at the other end. Here, the station is open in a kind of trench. There are four platforms, all serving the Metropolitan line, with the outer two platforms for terminating and the inner two platforms for through trains. The branch of the original Metropolitan Railway served by these platforms opened in 1868, only five years after the other platforms. Today’s layout of these platforms has been mostly established in the 1920s. I do not know whether these buildings are commercial or residential, but living here would be rather cool. We just jumped to the other platform with a departing fast service to Chesham. Fast services are only operated during rush hour. The train on the opposite platform begins here and is a semi-fast service to Watford. Meanwhile there is another though service to Aldgate approaching. The tunnel in the background leads non-stop to Finchley Road station, after which the line runs above ground. View from the same location in the other direction. This train will shortly join the Circle and Hammersmith & City line tracks. This is a slow “all-stations” service to Watford… which is followed by this semi-fast service, the last one in this film.
