London Transport Museum
London Transport Museum has a wide array of public transport displays from the last 200 years. The museum is conveniently located in Covent Garden.
The museum is an exciting journey into the past of London's public transport. The travel to the past starts already when getting on the lift. Transport modes from many different eras are shown when getting down to the museum area, starting with horse-drawn carriages to the building of the new underground lines. The museum also explains how using public transport has changed and how it has affected London. Tickets and posters from the past are also an interesting thing to see at the museum.
The museum, of course, has its souvenir shop, with products related to the items in the museum.
The museum is in Covent Garden, and the easiest way to get there is via the Covent Garden underground station. The area is part of West End, so walking is also a good option if you're planning on visiting Piccadilly Circus or Leicester Square. The nearest train station is Charing Cross, about 10 minutes away.
