Triebwagenhalle Velten, Railway depot in Velten, Germany

The Triebwagenhalle Velten is a railway vehicle maintenance facility consisting of multiple connected structures with a 25-meter water tower. The complex now operates as a service and commissioning center for newly manufactured rail vehicles.

The Reichsbahndirektion Berlin had architect Richard Brademann design the hall in 1926, and it opened on 15 November 1927 as a stabling and workshop site for S-Bahn trains terminating at Velten. It stored ET 168 and ET 169 sets, later ET 165 (class 275 from 1970), and from 1966 to 1969 two ET 166 quarter-trains. Electric S-Bahn service ended on 21 September 1983, after which the depot passed to the Wustermark works.

The lettering "Vor Einfahrt Halt" above the hall gates is a period railway instruction still legible on the brick facade. The site is now a Stadler service and commissioning centre, where newly built rail vehicles undergo acceptance tests before delivery.

The complex is located next to Velten's main train station and is easily accessible from the town center. You can view the structures from surrounding paths, and the site remains visible and approachable from various angles around the station area.

The isolated electric operation between Hennigsdorf and Velten after 1961 was not cross-border: both towns lay in East Germany, and the line was cut only between Hennigsdorf and Heiligensee. A substation at Hennigsdorf and this hall kept the S-Bahn running on the severed stump, which was reassigned to the S-Bw Friedrichsfelde and staffed from Oranienburg.
