MoComp Bogies
Global Competence Center for Bogie Technology
The Siemens Mobility global competence center for developing and manufacturing bogies, pantographs, and bogie components in Graz-Eggenberg, Austria, is one of the world’s largest sites for the development and production of bogies for rail vehicles. Decades of experience and reliance on the latest technological standards ensure the optimal and always reproducible quality of end products. The location features the world’s highest level of automation in bogie production as well as bundled expertise across the entire lifecycle. The close interaction between predevelopment, development, production, project management, and customer service and the strong collaboration with Graz University of Technology guarantees a focused implementation of the latest innovations while also exploiting the full potential of the digital transformation.
High tech for high-quality rail transport
Bogies are developed, engineered, manufactured, and assembled at the Graz location. Our bogies make an important contribution to travel safety (stability, protection against derailment), enhance travel comfort, permit reduced noise emissions, and guarantee the least possible wear and tear on wheels and infrastructure.

Success on the world’s rails
Our bogies are characterized by constant innovation and decades of experience, qualifying them for use in all modern rail vehicles. Light, economical, reliable, and comfortable, they perform your customers’ tasks exactly as you want them to: inconspicuously but on the highest level.Innovations that help you get ahead
We offer you market- and future-oriented system solutions that boost your competitiveness, both now and in the future. The future begins today – with innovations that focus on the growing requirements for energy efficiency and resource saving while setting new standards in terms of safety and quiet operation.
Optimized lifecycle costs
A bogie’s maintenance costs can amount to as much as 300 percent of the purchase price over the whole lifecycle. For many operators, this cost factor is becoming increasingly significant. The main factors that reduce maintenance costs for bogies are easy accessibility and removal of replaceable parts, optimized stiffness of elastic parts, and the use of active elements in the wheelset guide to reduce wheel wear. Diagnostic systems in the bogie also permit condition-based maintenance of the bogie and its components.
Consistently light-weight design pays off
Energy costs are part of the lifecycle cost (LCC). Energy efficiency in bogies is mainly achieved by reducing the weight of heavy components such as bogie frames and wheelsets. State-of-the-art construction and calculation methods make it possible, for example, to reduce the weight of the frame by up to 40 percent.
Wonderfully quiet operation
Traveling comfort and quiet operation are guaranteed by the bogie. Siemens bogies from Graz satisfy the highest demands for comfort, whether in sleepers and couchettes, on coaches, or in high-speed transport.
Maximum safety
From the very start, our job as manufacturer is to ensure the safety of the finished vehicle during each individual step of development and production. We do this using appropriate processes as well as state-of-the-art tools and simulation methods. Diagnostic and monitoring systems in the bogie permit real-time monitoring of component functions that extends all the way to obstacle and derailment detection.
