Rail Joining – THERMIT® Welding and Insulated Rail Joints

With our Thermit® welding processes nearly all rails of various profiles and grades worldwide can be continuously welded. Thermit® rail joining 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 Maintenance and Repair of Railway Tracks

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

Intelligent Predictive Maintenance of Railway Tracks

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. Intelligent predictive maintenance of railway tracks allows you to 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 hardening and weld-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 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 Devices and Services

Modern track measurement 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

Rail Track Tools and Equipment

We offer a high quality range of rail track tools and equipment to ensure your rails are always in operation.

Our self-regulating switch heating SMARTSWITCH HEAT keeps the rail warm to prevent problems. The special self-regulating heating cable ensures a distribution of the heating output which is suitable for the requirements of the rails and switch components. This prevents overheating and reduces energy consumption at higher temperatures. An additional temperature and snow sensor measures the ambient conditions. Based on the set values a controller automatically turns the switch heating on and off. The combination of these two measures ensures an efficient and secure operation.

TRACKSAFE LUBE is an intelligent lubrication device to reduce rail wear and noise with an intelligent control unit that allows lubrication to take place only when needed making the dosing very economic. TRACKSAFE LUBE is suitable for all rail profiles. It is equipped with a solar module enabling independent, energy-saving power supply. TRACKSAFE LUBE can be used in urban and non-urban areas and is quick and easy to install.

The magnetic barriers TRACKSAFE BARRIER guarantee absolute safety when working on all types of railway tracks. The fixed barrier ensures an effective guard on the side when working in the danger area of the tracks. The special feature of the system is the use of a strong magnet to enable quick and easy installation without the need to remove ballast.
