MoComp – our rail components and systems
Made to move
Success on the rails has always depended on the right components. From pantographs and propulsion systems to bogies and braking systems - with customized technology, Siemens Mobility offers you a component family of the highest quality: MoComp products for rail vehicles of all kinds are developed by us as a vehicle manufacturer for you, as a vehicle manufacturer and operator. With proven know-how, innovative and competitive technologies, we are your reliable partner with global reach.
Secure your head start: In our webinar on September 2nd, 2022, from 1 to 2 p.m. (CEST),
Andrea Estrada-Hein, Head of Components, will give you first insights into the MoComp portfolio, our trade fair program and our latest innovation, the air-free brake system.
We keep things moving – for 140 yearsTake advantage of our 140 years of experience in developing and manufacturing superior railway components. MoComp is your partner for optimized pantographs, traction converters, motors and gear units, brake systems, and bogie technology for all types of rail vehicle.
Testing with all the extras
Watch this video to learn about the entire range of testing options available at the ISO 17025-accredited Siemens Mobility System Test Center for traction drives in Nuremberg. This is where MoComp traction components are tested under real-life operating conditions according to the IEC 61377, IEC 60349, and IEC 61287 standards.
The air-free brake system from Siemens
With the new electric fiction brake system, the friction brake in rail vehicles is controlled entirely by electricity for the first time (brake-by-wire). As a result, the brake system in the vehicle uses no compressed air at all. Robert Steinfelder and Jens Lichterfeld played a key role in the development and launch of the innovative Siemens Brake.
Silicon carbide – a material that developers dream about
Dr. Bernd Laska is head of development for MoComp traction converters at the Nuremberg location. He’s at the forefront of efforts to further develop rail vehicles and their drive trains and to meet the ambitious energy efficiency targets of both vehicle manufacturers and customers. The key is silicon carbide – SiC for short – a new semiconductor material with excellent properties that is especially beneficial when used for designing traction converters. We asked him about the prospects for this new technology.
National, international, whatever?
With its MoComp product range and its selection of global locations, Siemens Mobility is pursuing a clear strategy: To always be as close as possible to the customer or the market, with quality you can rely on and a comprehensive range of services at every location. Our customers benefit most – since we know their products and are most familiar with the local regulations. But that isn’t all. Discover more about how you also can benefit from this special strategic structure.
All for one and one for all!
Sounds good, but what’s in it for customers?

Data hunters and gatherers
Bogie maintenance is an important subject for all rail operators. Denis Becker is part of a development team that’s putting bogie diagnostics on an entirely new footing. The MoComp Bogie Diagnostic Solution now provides him and the service team at the Siemens Mobility Rail Service Center in Eving, Dortmund, with real operating data so they can assess the bogies – with many positive outcomes.
Perfection taken to the extreme
Bogies are the components of a rail vehicle that are subject to the highest loads and forces. In an interview, Dr. Stefan Erlach talks about MoComp bogies and the Graz location, and about the bogies’ effect, for example, on the vehicle’s safety and riding comfort as well as its noise levels.
Being a pioneer
MoComp is more than just a name for outstanding rail components. It’s a commitment to being a pioneer. We put our components to the test in digital simulations, in the freezing cold, and in extreme heat. For us, that’s what being a pioneer is all about: always using the latest technologies to design, build, and test our components – and to revolutionize them so they optimally meet your requirements.
Railway gear units now under the Siemens brand as part of MoComp portfolio
What has long been part of Siemens now bears the Siemens brand. Rail transmissions from Siemens Traction Gears Penig GmbH, a 100-percent subsidiary of Siemens Mobility GmbH, were still sold under the Flender brand after the power transmission specialist was acquired by Siemens AG in 2005. With the sale of Flender to Carlyle, use of the Flender product brand ceased. Our rail transmissions now appear under the Siemens brand. Read more about our Penig location and Siemens rail transmissions from the MoComp portfolio.
Auxiliary converters – state of the art
On-board comfort and information are becoming increasingly important for your passengers, as are air conditioning and ventilation. This underlines the growing importance of the power supply for on-board electrical consumers. Our innovative auxiliary converters with SiC (Silicon Carbid) technology are the critical link between these consumptions and the vehicle power supply: small, lightweight, and extremely efficient.
