TRACK TECHNOLOGY
Thermit Welding (GB) Ltd is probably best known as the leading supplier of Aluminothermic welding materials and equipment to the rail industry
T
he company provides the means to weld virtually every known rail profile
that exists in the UK, covering high speed, heavy haul, urban and light rail systems.
What is less well known, even to long- serving track engineers, is Thermit’s range of products and services developed to offer solutions to the track engineer, all of which are operated under Thermit’s services division, TWS.
Welder Training is and always has been an important part of Thermit’s commitment to its clients, providing concise and practical training to the trainees using the most up-to-date techniques.
The instructors are experienced welders who have acquired full certification for assessment and teaching and are also heavily involved in Thermit’s product development programme.
Track Metrology, involving VERSE and Tracksafe Release, is for determining the stress-free temperature measurement in rail and corrugation measurement using the R2S electronic straightedge is provided by operators who have been instrumental in the development of the equipment and techniques.
Track stabilization is an area that Ther- mit has been operating in for over ten years, using its renowned Ballast Bonding technique.
Simply, the material is a two-part material that is mixed and delivered at the point of installation, being used to create beams of ballast at the end of sleepers to prevent lateral movement; to create transitions, varying the ballast modulus from slab to ballasted track; maintaining ballast profile on track with differing heights and cant and to prevent ballast movement in ar- eas affected by track maintenance such as
water-jetting. All of this is achieved whilst maintaining and adding to the water drain- age capability of the ballasted area.
Smartweld is a suite of products, which have been designed to raise the level of weld installation quality, by aiding the welder, as well as recording the core pa- rameters of the operation.
More products are being planned this year to complement the Smartweld Control.
Added to these products and services are Alphatek coating removal, Ballast Boards, weld inspection and analysis and weld pro- cess development for unusual rail profiles.

With increasing uncertainty on weather patterns, STEGO outlines the importance of acclimatising enclosures.
S
TEGO has decades of experi- ence in the field of climatisa- tion of enclosures and control pan- els, traffic control and monitoring systems in the transport industry and rail signalling techniques. Inno- vation and design are central to our product development philosophy.
Due to fluctuating temperatures, condensation can form in enclosures. This can lead to serious malfunctions or, worst case, to component failure. STEGO heaters protect against low temperatures, thus preventing the formation of condensation.
The company’s CS heating product range is ideal for railway enclosures where space is crucial. The heaters are quiet in operation and are vibra- tion resistant. Models with plug-in thermostats that do not require ad- ditional wiring are also available.

The casing is plastic according to UL94 V-0.
Filter fans protect against overheat- ing in enclosures, preventing mal- functions of electrical and electronic components by diverting the warm air away from heat sensitive com- ponents; the mounting and design frame prevents dust and water from entering the enclosure. Our unique outdoor filter-fan is lockable.
A prerequisite for the clean opera- tion of signalling equipment is the right climate in the enclosure. Ther- mostats and hygrostats are used for the control of heaters, filter fans, heat exchangers and air condition- ing equipment. The new STO series with a Thumbwheel setting dial has an anti-frost assurance.
