Our product and service portfolio ranges from continuously welded tracks, rail services, measurement, tools and machines to equipment. We know exactly what is required for the successful long-term operation of high quality tracks. In this way, taking pioneering steps into the digital work site is the logical consequence of our dedication to research and development. In the future, more and more processes and tools will be connected so that they can communicate intelligently with each other to achieve the highest degree of precision, quality, efficiency and comfort in new construction and maintenance. Take advantage of this expanded, unique service portfolio for greater safety, reliability and availability for your tracks and discover new potential for added value together with us by digitalizing work processes in all facets of the railway infrastructure.

Rail Joining

With our Thermit® welding processes nearly all rails of various profiles and grades worldwide can be continuously welded. Thermit safely and quickly connects rails with different Thermit welding processes, which are suitable to specific customers. Implementation is characterized by very low demands in material, time and manpower, and offers the highest standards of quality and reliability. The significant mobility and applicability of this method means that welding can proceed under traffic. We develop, manufacture and supply all components required for our Thermit® welding processes.

Our experienced welding specialists carry out arc welding with the submerged arc welding technique and the manual metal electric arc method.

Insulated rail joints are required to determine the position of the train for the purpose of safe signal control. We produce and market various types of insulated joints with different properties according to the type of force application, installation and manufacture. Their common advantages are: they offer the highest safety, reliability and durability – in all climates. All our insulated joints are manufactured from steel or polymer composites.

Rail Services

For rail services you benefit from the reliable and perfectly coordinated range of services for the maintenance and repair of railway tracks:

  • Joint welding of rails and switches
  • Grinding work
  • Intelligent predictive maintenance for rails and switches
  • Weld-tempering of new rails
  • Ballast stabilization

Intelligent Predictive Maintenance for Rails and Switches: Professional maintenance is an important preventive measure against wear due to heavy rail traffic and serves to sustainably lengthen the service life of rails and switches in subway systems, tramways, light rail and mainline networks. This means you work more efficiently and your network runs according to schedule– safely, reliably and with a long life. Thanks to our highly mobile equipment, our teams are particularly flexible; they are able to manage the required welding and grinding work also on existing rails where access can be difficult – quickly and efficiently.

Weld-Tempering of New Rails: We can offer tempering and hardening of new rails according to customer specific requirements. The gauge corner, gauge face and running surface of rails are weld-tempered by milling the rail and applying new wear-resistant weld material to rebuild the section. This method secures a significant reduction in vertical and lateral rail wear and ensures safety of traction operations in the long term. Thanks to the extended lifespan of both the rail and the entire superstructure noise emissions are minimized, while maintenance costs are reduced.

Track Measurement

Modern devices and state of the art technology is used to fulfil various measurement tasks and special work assignments, complemented by a broad and application-specific range of measuring devices. We develop most of the rail measurement technology ourselves. At all times we guarantee you maximum safety, high quality and availability of your tracks, preventive maintenance and improved comfort for passengers.

We offer a wide range of products for measurement technology including:

  • Long / short-time stress measurements and stress-free temperature
  • Longitudinal and cross-section as well as rail surface roughness measurements
  • Track position and stability measurements
  • Track geometry testing and switch inspections
  • Measurement of turnout systems
  • Ultrasonic testing and inspections
  • Bridge and component testing
  • Calibration and maintenance service

Tools & Machines

We offer a wide product range of efficient tools and machines for various applications like Thermit® welding, track construction and maintenance as well as numerous hydraulic power units to drive the equipment and also for use with applications in many other industries and measuring devices. Our tools assure the safety and the comfort of the workers using the tools, are reliable thanks to the use of high quality components and reliable equipment.

Road-Rail Vehicles

Our SRS road-rail vehicles can be used both on rail and on the road and are custom made to meet your needs and requirements thanks to different attachments and superstructures. Your benefits:

  • Patented road-rail system equipped with a hydrostatic drive
  • Rapid transport to and from the work site
  • Speed up to 100 km/h on tracks (forward & reverse) and up to 90 km/h on the road
  • The rail system requires only 3 to 5 m of a level crossing to transfer from the road to the track
  • Fast and safe driving on and off the track in less than 2 minutes
  • No risk of derailment at crossing points, wing rails and level crossings
  • No special speed restriction requirements for curves, switches and at level crossings
  • Remote control of the vehicle
  • All vehicles are custom made to meet customer needs and specifications
  • All vehicles comply with EN 15746/RIS1530
  • The SRS service team ensures reliable operations and a long life for your vehicles

Railway Equipment

We offer a high quality range of equipment ranging from switch heating to rail lubrication systems and magnetic barriers that guarantee absolute safety when working on all types of railway tracks.

About Goldschmidt Thermit

The imperial patent no. 96317 marked the begin of a real success story: in 1895 Prof. Hans Goldschmidt of the company Chemische Fabrik Th. Goldschmidt AG, founded in 1847, developed the alumino-thermic process – the Thermit® process for continuous welding of railway tracks. In the following years, various partner companies were founded around the world, giving rise to a group that today boasts almost 1,000 employees in 20 countries.

The spirit of the inventor of the Thermit® welding process, Prof. Goldschmidt, remains with us today: through the drive to do things better, improve existing processes, and develop new ideas. We can offer you a unique range of products and services for more efficiency, more safety and more travel comfort on your railway tracks. Whether construction, renovation, modernization and intelligent predictive maintenance of railway tracks – with us you’re moving on safe tracks.

Certificates and approvals of our companies include quality management certification according to ISO 9001:2008 and AAR M-1003, approval by all major railway companies in more than 80 countries and approval as a Q1 supplier for Deutsche Bahn AG.
