Modellbahnwelt Oberhausen, Model railroad exhibition near CentrO, Oberhausen, Germany.

Modellbahnwelt Oberhausen is a model railroad exhibition featuring a large layout that recreates a regional industrial landscape. Thousands of buildings, vehicles, and figures bring this miniature world to life.

The exhibition opened in 2008 and depicts the Ruhr region as it appeared between 1965 and 1970. This period captured the industrial activity and daily life that defined the area during that era.

The exhibition displays miniature versions of recognizable local landmarks, including Villa Hügel and Oberhausen's Gasometer. Visitors can spot familiar buildings and places they may recognize from their own experience.

The layout occupied 420 m² in the Neue Mitte Oberhausen, next to the Heinz-Schleußer-Marina and east of the CentrO grounds, beside the A42 motorway. The building later housed the TOP SECRET spy museum from April 2012 to May 2015, so the model railway can no longer be seen there.

The layout's most noted feature was its photorealistic backdrop, described as the largest of its kind in the world, which gave the 420 m² H0 installation a pronounced sense of depth. A planned second section showing the Ruhr after deindustrialisation was never built because management filed for insolvency in April 2009.
