STAIRS AND FOOT BRIDGES
Network Rail categories B, C, D, E & F
Stairs and Foot Bridges
Stairs and bridges may be open, enclosed and of varying construction. Good lighting can go some way towards maximising safety and capacity. Lighting should highlight the walking surfaces, treads and risers. It should also help create sufficient contrast between adjacent surfaces for maximum visibility, whether sparsely or fully occupied.
Lighting from each side can give sufficient directional quality of light. Equal highlighting of horizontal treads and vertical risers on the stairs is important whilst maintaining the natural lit contrast between the two. Luminaires mounted at low level can minimise troubling glare. Care should also be taken to minimise glare to train drivers and dispatchers.
Lighting could also be provided by column mounted luminaires either around the bridge or mounted on it, or a combination of both. Care should be taken to achieve suitable levels of uniformity.
In many situations, lighting could be fully exposed to the elements, making high IP rated luminaires essential. Moreover, for longevity and to minimise costs, the external finishes of luminaires should be highly resistant to degradation.
Designplan have produced a comprehensive overview of potential lighting applications for Network Rail Category B, C, D, E, F. Applications include everything from platforms, forecourts, subways through to public toilets.

There are some differences in recommended levels across standards. EN12464-2:2014 calls for 50 or 100 lux in outdoor applications dependant on passenger numbers. Whilst the Rail Industry Standard calls for 100 lux on footbridges and 150 lux on stairs.
In our experience 150 lux throughout is often selected for covered applications. BS 5489-1:2013 calls for 15-30 lux outdoors and 150 lux for enclosed areas.
In all cases due consideration should be given to contrast between adjacent areas and surfaces.

We have attained an enviable reputation as the supplier of choice in rail applications, having completed many successful projects for both overground and underground facilities.
Designplan Lighting have built a reputation for products engineered to stand the test of time.
Our luminaires incorporate metal bodies and specially designed diffusers which can resist up to 250 joules of force – 12.5 times more than an IK10 fitting (20 joules). High ingress protection and corrosion resistant paint are other key components of our “robust and durable” ethos.
