New hi-vis fabric
Initiatives to reduce workwear costs and waste while improving safety were the focus of the PHS Besafe stand. Among products on show was ThermGuard High Visibility, a new high visibility heat- and flame-resistant fabric from Toray Textiles Europe Ltd. Conforming to all UK industry standards, including GO/RT 3279, and offering protection against the thermal hazards of an electric arc, the fabric is breathable, comfortable to wear and stable to industrial washing.
Commenting on other company innovations, PHS Besafe Managing Director Lynne Vanes said: “We’ve also introduced high visibility garments manufactured from a unique polycotton fabric that’s been proven to be able to be laundered for up to twice as many washes as many existing products. We want to ensure customers are achieving the best possible lifespan for their workwear, as by increasing the working life of the garments, the frequency of purchasing is reduced.”
RVEL offers EMD support, launches new division
The Railway Vehicle Engineering Ltd stand at Railtex was used as a formal launchpad for its recently announced partnership with US-based National Railway Engineering Company for the supply of EMD locomotive parts and re-engineering services in the UK and Ireland. In the UK alone there are more than 500 EMD-built or -powered locomotives, notably the Class 66s used by all freight operators. Company engineers have recently undergone the EMD Applied Training Programme in the US. Managing Director Andy Lynch said: “With our key
engineering staff now fully trained on EMD engines and by holding parts at our Derby site, we can offer users of 645 and 710 engines unrivalled turnaround times, allowing fleet owners to maximise vehicle hours in traffic.” RVEL also launched its new Technology division at the show,
offering specialist welding and materials services. Services offered by RVEL Technology include material and component failure investigations, non-destructive and ultrasonic testing and collision and damage repair to bogies and vehicles.
Pipework for tunnel heat capture
Polymer specialist REHAU exhibited its PE-Xa (cross-lined polyethylene) pipework for the extraction of geothermal heat from tunnels, including rail applications. The product featured in one of the Rail Engineer seminars when Commercial Manager Mike Moseley, set out the concept and explained how the technology is already being used in mainland Europe to heat both residential and commercial buildings and to cool tunnels by removing excess heat build-up. Using a detailed case
study from a recent tunnel installation in Austria, Mike explained how loops of polymer absorber pipe can be positioned inside pre-

fabricated tunnel lining segments to extract energy. Assembled within a steel mesh or cage, the loops are inserted into each tunnel mould segment before concrete is poured and the segments are then joined together with a keystone to create the tunnel ring. The pipework is connected into a continuous loop using REHAU’s EVERLOCTM compression sleeve fitting. When the loops are activated, heat energy from the ground and from the operations taking place within the tunnel is transferred to the fluid circulating within the pipework and carried to the surface where it is extracted via a heat pump.
