Ride a historic A1 train on Berlin's U4 with a normal BVG ticket

A Berliner Zeitung culture-and-service piece highlighted around 18 October 2026 draws attention to a treat for Berlin transit fans: the BVG is operating a restored historic 'A1' U-Bahn train on the compact U4 line between Nollendorfplatz and Innsbrucker Platz. Unlike many museum rides, this one is included in a normal BVG fare: any valid ticket allows passengers to climb aboard the vintage small-profile carriages, admire the wooden benches and original fittings, and travel the full five-station U4 route through Schöneberg. The article explains the A1's role in Berlin's U-Bahn history, how the restoration was carried out and when the trains run on the U4 timetable. It is pitched as a cheap, low-threshold weekend outing during the autumn holidays and is among the most-read Berlin service reads of the week.
