Updated for 2026: This is still a great niche stop for transit fans, but opening days can shift and visits may be limited, so check the latest schedule before you go.
The Berlin U-Bahn Museum is housed in a former signal box at Olympiastadion station, where the switches for this busy part of the network were once controlled. It's a rewarding stop for anyone curious about Berlin's underground system, and an easy pick for rail enthusiasts in general.
Inside, the museum traces the story of the U-Bahn through vintage carriages, technical equipment, and other pieces you won't come across in everyday service. Much of it is still operational - it simply belongs to an earlier era of the network.
From the balcony, you can look down into the hall with the trains, including cars similar to the ones still running today. The collection also includes smaller but fascinating items - historic line maps, old tickets, and displays showing how the Berlin Wall once split the system in two.
The downside is that the museum is usually open only once a month, so it's wise to check the date in advance and plan your visit around it.
