The Munich locomotive plant today

Vectron is built at the Siemens locomotive plant in Munich-Allach. Within Siemens Rolling Stock, the Munich plant is the lead factory for locomotives and competence center for steel construction. Locomotives are manufactured using state-of-the-art production technologies as well as highly flexible assembly methods based on the Siemens Production System, resulting in maximum benefits for our customers and the environment.

Munich location

Siemens locomotives are manufactured in Munich-Allach, on 24,500 square meters of roofed production area. Here a vehicle passes through all phases of production, assembly and commissioning. Part of the development work is also carried out in Munich. In total, approx. 700 people are employed at the Munich plant.


Using state-of-the-art design and calculation tools, our engineers create products that meet the requirements of the market, of our customers and comply with all standards as well as homologation specifications. In today’s market environment, additional parameters that are considered in the development and design process include derivation of target costs, environmental factors, and life-cycle costs.


Coach body production is a core expertise at our Munich plant. Apart from conventional welding, we also employ robot welding systems in our steel production shop.


The painting shop is geared to the use of environment-friendly, water-based paint systems. Here the coach bodies are given a durable and elegant external finish according to the customer’s design requirements.


Another core expertise of the plant is the preassembly of modules, for example the cable harness and piping ducts.

Final assembly

The final assembly shop is laid out efficiently according to the Siemens production system (SPS). Here coach bodies, large components such as converters, transformers (both from Siemens plants in Nuremberg), bogies (from the Siemens Bogie Competence Center in Graz, Austria), and other components manufactured at the plant (the front end and pipe and cable ducts, for example) are assembled into complete locomotives, followed by a final inspection.

Testing and commissioning

Before handover to the customer, every locomotive has to undergo a series of tests. There are two different types of tests: static and dynamic. In addition, every new locomotive type is subjected to a series of type tests.


Stationary commissioning

The following voltage systems are available for testing and commissioning in the commissioning hall:

  • 1.5 kV DC

  • 3 kV DC

  • 15 kV 16 2/3 Hz

  • 25 kV 50 Hz


Dynamic commissioning

A 450-meter test track is available at the Munich plant for driving and braking trials. There, too, electric locomotives can be supplied with the four voltage systems noted above. The maximum speed is 40 kilometers per hour. At present, the test track can handle locomotives with the following gauges: 1,000 mm, 1,067 mm, 1,435 mm and 1,668 mm.

Waterproofness and other tests

A sprinkler system is available for testing the waterproofness of the vehicles. We also have other test facilities available, especially for type tests, at Siemens’ Test- and Validation Center Wegberg-Wildenrath.Test- and Validation Center Wegberg-Wildenrath.


The ongoing operation of the locomotives by the customer is accompanied by product observation as well as the collection and analysis of field data. The results are then incorporated into the development of our new and existing products. A broad portfolio of services within the framework of Vectron Railcover supports the operation of locomotives in accordance with the customer’s needs.
