Invensys wins London Bridge resignalling job


F


ibe-optic cable from Huber+Suhner has been au- thorised for use across the Lon- don Underground network after meeting the fire, smoke and toxic fume requirements of LUL’s 1-085 standard.


The metal-free LSFH cable is a multi-fibre, loose tube fibre-optic cable designed for systems and equipment that need fast data transmission rates, including sig- nalling, platform information sys- tems, video links and CCTV as well as ticketing systems.


The firm’s commercial director, Phil Stanway, said: “By complying with the rigorous standards de- manded by London Underground our new fibre optic cable will now find wide application throughout the rail industry.”


The 1-085 specification details the most demanding flammability, smoke emission and toxic fume emission test requirements that


Network Rail has chosen Inven- sys to handle the resignalling at London Bridge station and the approaching railway in the “most complex and ambitious” such scheme it has ever undertaken.


Invensys is the first of three ‘delivery partners’ with whom Network Rail will form the London Bridge Area Partnership to reconstruct the station and railway infrastructure.


products have to meet to be used on passenger and engineering trains, tunnels and underground stations.


The purpose of the standard is “to ensure that the risk to which the public and employees are ex- posed is controlled to a level that is as low as reasonably practica- ble”.


The toxic fume emission test, for example, is designed “to confirm that all combustible materials do


not contain halogens, nitrogen, or sulphur, which are known to potentially give rise to toxic fume emission”.


The testing has been carried out by an accredited test house using a qualitative analysis. An x-ray flu- orescence spectroscopy process confirmed that none of these ele- ments were present in the cable construction.

Simon Kirby, Network Rail’s director of investment projects, said: “This is a great example of how we are changing the way we work to encourage more innovation, deliver projects in a smarter way and get better value for money. By involving our delivery partners at an early stage, the industry will be able to deliver one of the most complex station, track and signalling projects being undertaken on the railway network in a generation.”
