Welding processes for railways
Thermit safely and quickly connects rails of all profiles with various Thermit welding processes, which are suitable to specific customers. Implementation is characterized by very low demands in time, material and manpower, and offers the highest standards of quality and reliability. The significant applicability and mobility of this method means that welding can proceed under traffic.
Insulated rail joints
We provide insulated rail joints (steel and polymer composite) that are either assembled in workshops or installed in position on the track. Today’s signaling and security technology at railways predominantly works with track electric circuits, where the rail assists as electrical conductor. At the demarcation point (block section) of the track circuits, the rail is interrupted by insulated fishplate joints, which is why the signal block sections of the track are marked off to each other.
We offer products and services for measuring stress-free temperature, track geometry parameters, straightness, surface conditions, position and stability. A constant and cost-effective maintenance management enables the highest driving comfort, as well as maximum track safety and availability to railway companies.
Using the most advanced devices and latest technologies, we carry out most various measuring tasks and special work assignments, complemented by a broad and application-specific range of measuring devices.
We can offer hardening and tempering 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 lateral and vertical rail wear and ensures safety of traction operations in the long term. Additionally, noise emissions are minimized, while maintenance costs are reduced thanks to the extended lifespan of both the rail and the entire superstructure.
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 safely, reliably and according to schedule. Thanks to our highly mobile equipment, our teams are particularly flexible; they are able to manage welding and grinding work on existing rails, where access can be difficult – quickly and efficiently.
Hydraulic power units
Goldschmidt Thermit Group is with its group company PortaCo, Inc., one of the largest manufacturers of portable hydraulic power units. We build quality and safe standard hydraulic power units and custom designs in many styles and sizes. We manufacture for Original Equipment Manufacturers and distributors internationally.
About Goldschmidt Thermit
The history of the Goldschmidt Thermit Group dates back to 1847 when the company Theodor Goldschmidt AG was founded. In 1895, Prof. Hans Goldschmidt invented the Thermit welding method, an aluminothermic process that enables sections of rail track to be welded together continuously. This marked the beginning of modern rail transport.
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.
Certificates and approvals of our companies include quality management certification according to ISO 9001:2015 and AAR M-1003, environmental management system according to ISO 14011:2015, approval by all major railway companies in more than 80 countries and approval as a Q1 supplier for Deutsche Bahn AG.
