The association Modelleisenbahn Hamburg e.V. (Mehev) operates a historical model railway in the scale 1:32 (Track 1). It is one of Europe’s largest and oldest model rail systems.

Since 1949, the trains in the museum travel on the 1200 metre tracks between Hamburg-Harburg station, the city’s main freight station and the “Pfeilerbahn” (pillar railway).

Alongside historical model steam engines, modern model trains, diesel engines and power rail cars also travel here.
