Besides its historical part (which, by the way, is excellent), the museum also has an important educational zone. In this photo you can see the Park Zone, a place which simulates for kids an entire railway. Miniature trains are operating by the same rules as the real ones and the visiting children can operate signals and a lot of other railway related systems.
I'm a girl, but I'm sure I would have loved this as a kid...
