What types of Railway Cables are used in and around a railway station?
Click below to explore the interactive image showing cables used in and around the station.
Ticket vending machines, CCTV cameras, lighting, clocks and fire alarm systems in railway stations use a number of different cables. Within each station lies a complex network of Coaxial cables, fixed wiring cables, Fire Integrity cables, telephone cables and data cables.
Fixed Wiring Cable
Steel Wired Armoured (SWA) PVC Cable to BS5467, SWA LSZH Cable to BS6724, 6491X Cable to BS6004 and 6491B Cable to BS7211 are all used to power the equipment that exists within a station – from the ticket machines and barriers, information displays and lighting systems to the lifts and escalators. In particular, BS6724 Cable – an LSZH SWA Cable – is a hard-wearing armoured power cable recommended for use in public areas – when exposed to fire, the sheath emits very low levels of smoke and non-toxic levels of halogen gas (typically under 0.5% HCl emission).
Fire Integrity Cable
Fire Integrity Cable, such as FireForce Fire Performance Cable PH30 and Section 12 Fire Integrity Cable, is installed in systems where vital circuit integrity must be maintained in the event of a fire. In a station environment, this includes Public Address systems (PA), Public Help Points (PHPs), fire alarm and CCTV systems.
Data and Telecoms Cable
Communication within a station and between stations is made possible with a network of data and telecoms cables. Analogue signals from CCTV cameras are circulated by way of Coaxial cables (such as CT100 Cable, CT125 Cable and RG/URM/Composite Cable) and digital signals are transmitted using Cat 5e UTP and STP Cables. These Cat 5e Cables are also found feeding information to and from ticket machines and barriers, clocks, information display systems, lifts and escalators. RS232 (Overall Screened Multi-Core and Overall Screened Multi-Pair Belden Alternative) Cables and RS422 (Individually Screened Multi-Pair Low Cap Belden Alternative) Cables are installed in clocks, and telephone cables – CW1308 Cable and CW1600 – Cable enable passengers to communicate with station support staff through Public Help Points (PHPs). Local Area Networks (LAN) and Wide Area Networks – made up of multi-pair copper cables and multi and single mode fibre optic cables – ensure information available in one station is shared between stations and control centres.
