• Cobralino pedal tram that kids drive with their own muscle power, pressing every button and pulling every lever
• An adult at all times, since the museum requires kids to be accompanied for safety reasons
• Museum tram line 21 runs vintage trams from the depot to the main station on the last weekend of each month (not December), and a regular ZVV ticket covers the ride

The museum fills the 1893 Burgwies depot, the city's oldest surviving tram depot, with original trams from 1897 to 1968. Kids can climb inside most of them, look at a tram from underneath, and see the motor through a glass floor.

For younger kids there's Cobralino, a pedal-powered tram they drive themselves, plus a big wooden railway, a model layout where kids run the trams, and a tram-sound piano.
