Currently (September 2011) the locomotive building department of Siemens is part of the Mobility branche. For locomotives, the factory in Munich-Allach is the most important location. This site is responsible for the design, production, construction and (for most locomotives) the assembly of the products. Sometimes the assembly is (contractual) outsourced. The OBB-work shops in Linz assembled the majority of ES64U2 and ES64U4 platform locomotives for example.

This section currently includes both electric (EuroSprinter/Vectron/other) and diesel-electric (EuroRunner/AsiaRunner) platforms.
