Best service for your rails.

The Goldschmidt Thermit Group provides for high performance rail networks

We provide you with reliable and perfectly coordinated rail services for the maintenance and repair of railways, and, ultimately, a modern railway network. In addition to welding and grinding work and the weld tempering of new rails the services also include measuring services and ballast stabilization. Our extensive range of services therefore makes a considerable contribution towards improving travel comfort, reducing lifecycle costs and secure the performance of your railway network.

Joint welding of tracks and switches

With our various welding processes nearly all rails and switches of various profiles as well as grades worldwide can be continuously welded. This guarantees the safe joining of rails while at the same time increasing travel comfort and the lifetime of the rails. As an end-to-end supplier we develop, manufacture and supply all components for our different welding processes.

Goldschmidt Thermit Railservice is an authorized welding specialist according to the certificate of suitability of class 1 following Ril. 826.1020 of the Federal German railways (Deutsche Bahn). Our welding teams, consisting of experienced welders holding certifications of class 1, carry out THERMIT® welding as well as electric repair and joint welding to the highest standards of quality. Additionally we provide the necessary accredited construction supervisors to conduct the stress equalization in order to manufacture the continuously welded track following DB Ril. 826.130.

Benefits

  • Welding of nearly all rails and switches
  • High quality welding through experienced welders
  • Restoration of the original rail profil
  • Increasing travel comfort and lifetime of rails

Grinding Technology

We machine your rails and switches efficiently and precisely using manual grinding, reprofiling and deburring machines and modern road-rail vehicles.

Range of services

  • grinding of new rails (removal of mill scale and damage from construction work)
  • removal of corrugations
  • deburring
  • re-profiling
  • removal of rail defects such as head checks, squats and wheel burns
  • acoustic grinding for considerably quieter train operations
  • switch grinding

Benefits

  • longer rail service life
  • lower maintenance costs
  • improved wheel/ rail contact for lower wear
  • lower noise emissions
  • preventive rail maintenance
  • flexible use of different grinding process and devices
  • high availability through excellent availability of grinding equipment  and grinding trains
  • rail gauge variable depending on device

Intelligent predictive maintenance of rails and switches

Professional maintenance is an important preventive measure against wear caused by 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 quickly and efficiently able to manage the required welding and grinding work on rails, switches and track where access can be difficult.

We use the following welding processes to carry out the work on your tracks:

  • submerged arc-welding
  • manual arc-welding
  • flux-cored wire welding
  • repair welding process THERMIT® HEAD REPAIR

Our grinding processes for your individual requirements:

  • manual grinding
  • mobile rail grinding machine GP 4000 to restore the rail profile of heads and joints on flat bottom rails
  • mobile reprofiling and deburring machine RAILSHAPE ECO and RAILSHAPE PRO
  • road-rail grinding machines RAILSHAPE EXPERT

Benefits

  • longer service life for rails, switches and wheels through:
    • prevention and quick removal of rail defects and wear
    • long-term prevention of corrugation formation through rail tempering
    • conservation of wheels through rebuilding of the original wheel profi le and through reduced surface roughness using our special patented material ETEKA 5®
  • considerable reduction of lifecycle costs of rails and switches
  • higher operational safety and avoidance of disruptions to operations through timely reconditioning
  • repair possible during normal operations
  • lower noise emissions
  • repeated reconditioning possible

Weld tempering of new rails

Highly wear-resistant materials are used to weld-temper new rails. The result is you receive a cost-efficient, comfortable and long-lasting product suitable for all new rail projects and renovation work. The reduced surface roughness of the used materials reduces wheel tire wear by up to 94 %. We offer running surface welding for use on tight bends in dense residential areas which substantially reduces noise emissions.

Weld tempering involves work on the gauge corner, gauge face and/or the rail groove. First of all the rail is milled before new, wear-resistant weld material is applied. 

We offer following products

  • SMARTTRACK SILENT for running surface tempering with ET 2000®
  • SMARTTRACK EDGE480for running edge tempering with ETEKA 5®
  • SMARTTRACK EDGE420 for running edge tempering

Benefits

  • economic thanks to high wear resistance
  • longer service life for rails and wheels
  • improved rail surface
  • formation of short waves delayed
  • tempering of all common grooved, flat bottom and customized rail profiles
  • rails bent according to customer requirements
  • just-in-time delivery to the construction area

Ballast stabilization and sleeper rehabilitation

A solid foundation for secure rail operations: our ballast bonding process holds ballast substrate together in many areas wherever this is required. This enables you to reduce maintenance costs, simplify the cleaning of train stations and stopping places, and lower noise emissions in town areas.

Application areas

  • stabilization for switches, insulated rail joints and deeper levels
  • transition areas between ballast track and slab track
  • prevention of flying ballast, in particular on high speed track sections and also in connection with vandalism
  • avoidance of damage to ballast bed through floods
  • sleeper restoration on slab track
  • easy cleaning for ballast surfaces in train stations and stopping places
  • non-slip coatings for platforms through liquid plastics based on epoxy resin and polyurethane resin

Benefits

  • lower maintenance costs with longer service intervals
  • low maintenance effort, long durability
  • sound-absorbing effect, e.g. for urban public transport areas
  • easy cleaning for ballast surfaces in train stations and stopping places
  • high environmental compatibility, special disposal not required
  • bonded ballast with full drainage capability
  • also easy to work with under extreme weather conditions
  • bonded ballast can be reworked, used elsewhere, or re-bonded
