Specialist fibre-optic solutions provider, Mainframe Communications, is now registered in the railway sector of the Achilles Link-up supplier qualification scheme. The scheme provides a single common registration process for suppliers to the rail industry, allowing purchasers to make fully informed buying decisions when selecting potential suppliers at the pre-qualification or tender stage.

Link-up collates relevant information about suppliers – including financial performance, health and safety and environmental policies, and products and services data – checking that it is accurate and current, and providing online access to this for potential purchasers in the rail sector.

Commenting on the registration, Mainframe’s business development manager, Paul DuGuay said: “We recognise the importance of being in the scheme and are now registered to supply into eighteen different Link-Up categories, meaning that purchasers can now more easily consider us for contracts in the rail sector. I believe that being Link-Up registered also demonstrates both our ability and our intent to build on our expertise and experience in the rail industry and to continue to develop tailored solutions to meet the needs of individual projects.

“Whilst our business was founded on the supply of high quality fibre-optic cable systems into other safety-critical industries worldwide, we are increasingly working in rail and are currently delivering solutions into a range of projects for the London Underground (including the Jubilee Northern Upgrade Programme) and Dubai Metro.”

Mainframe Communications supplies fibre optic distribution frames and cubicles, termination and splice assemblies, and patching arrangements for rail applications such as signalling, transmission, telecoms, SCADA and advertising systems.
