If you are a ‘railway-phile’, and you are in Tokyo, I recommend to you the Railway Museum (????????????え).
The Railway Museum is a museum in Saitama, the prefecture in the north of Tokyo.
The museum exhibits real retired train cars from Japan and abroad.??The exhibitions shows you?the history of rainways in Japan, from the British made locomotive to the uniquily Japanese Shinkansen.
There are also miniature railway models as well as the real trains.? The diorama in this museum is the largest in Japan.
There is a hands-on exhibition, too.? You can sit in the real cockpit of a steamer, electric train, and Shinkansen, and enjoy a simulating game as the driver!
