MoComp – our rail components and systems
Made to move
Success on rails has always depended on the right components. Siemens Mobility has now bundled its reliable, innovative, efficient, and propulsion-related component portfolio under the MoComp family name – from pantographs and traction converters to brake systems and bogies. The technology is tailor-made for any application, and developed by a vehicle manufacturer for vehicle manufacturers. Better rail vehicles with MoComp components – made to move.
Brake systems
Siemens brakes: developed by an expert vehicle manufacture, perfectly integrated in your vehicle, bogie, and drive architecture.
Bogies
Our first choice for all types of high-performance rail vehicle: light, energy-saving, and comfortable.
Auxiliary converters
Small, light, powerful, and with an optimized power density: modular and service-friendly design for optimal availability.
Traction converters
The highly-developed, modular platform solution for all rail systems: efficient and reliable with state-of-the-art power electronics.
Gear units
Innovation and experience, 100-percent load-tested quality, more than 140,000 rail gear units delivered: optimal performance for your rail vehicle.
Traction motors
Move better with our motors: distinctly reliable, durable, and energy-efficient.
Pantographs
The basis for reliable and efficient operation: high-quality contact between pantograph and contact line.
We keep things moving – for 140 years
Take 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.
The new airfree brake system from Siemens Brakes
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.
