Chiltern Railways was in desperate need of a cost slashing innovation to reduce energy usage and an inventive application of LED technology offered the answer.
The Arriva owned company has updated the internal and external lighting at three major stations, Wembley, Aylesbury and Stourbridge in the south of the UK.
Energy-intensive 400W highbays at the Wembley and Aylesbury maintenance depots were replaced with hooked LED highbays in a range of wattages and a sustainable, higher efficiency, longer lamp life replacement for traditional 2D bulk heads, was installed in the staff shower and toilet facilities at Wembley.
The offices on both sites were kitted out with ultra slim ceiling panels that deliver high performance and attractive LED lighting. Fluorescent tubing has also been removed and replaced with highly efficient non-corrosive LED fittings, to act as a lower energy consumption alternative.
The LED highbays installed at the Wembley and Aylesbury maintenance depots delivered a 67 per cent and 48 per cent saving in energy consumption respectively. Both sites also realised a further 64 per cent reduction in energy usage thanks to the new ceiling panels.
A mix of LED amenity, street and area lighting products were also installed to deliver optimum illumination in a number of outside areas, including pathways around and access roads to the railway tracks.
External lighting solutions included the installation of twenty seven 40W SmartScape Nano street lights from Zeta and more than thirty Zeta LED flood lights in various wattages in the Aylesbury depot.
A further thirty flood lights were installed to illuminate the tracks at the Stourbridge site and another 285 replaced the legacy 40W twin CFL lights along the pathway running adjacent to the railway track at Wembley.
In all three locations, this provided Chiltern Railways with a low power, high quality LED replacement for the incumbent energy-intensive flood lighting.
Emergency lighting at Wembley which had proved to be problematic, was also upgraded.
At Stourbridge, replacing the energy-intensive legacy lighting alongside the tracks with flood lights resulted in a 62 per cent reduction in energy consumption. Furthermore Chiltern Railways will achieve an average 61 per cent reduction in CO2 emissions.
In addition, Chiltern Railways no longer has to factor in time or budget for maintenance. Chiltern Railways estimate they will benefit from a further reduction in spend of around £10,000 per annum, the amount it previously cost to maintain the lighting infrastructure.
Another benefit has been a dramatic improvement in the quality of light. The external areas are now brighter, more secure and offer safer working environment for the company’s employees.
The superior uniformity of light and improved illumination within the offices, has also been well received by Chiltern’s staff.
