Adelaide Showground railway station is located on the Belair and Seaford/Tonsley lines, and is located in the inner western Adelaide suburb of Keswick. Permanently replacing Keswick Station and the showgrounds’ temporary station, the new Showground Station provides improved services to patrons and supports the showground’s major events that generates more than 1 million visitors per year.

Working closely with the Consultant, Jacobs-SKM, Versalux assisted in offering a truly unique and innovative approach to the project’s objectives, whilst maintaining the cost-effective solution with the luminaire selection. Mounted continuously end-to-end under canopies above the 160m long platforms, the LED luminaires provide superior horizontal and vertical illuminances. This assures safety to patrons, and embraces the principles in Crime Prevention Through Environmental Design, based on the mass passenger transport modelling data. In support of the linear LED luminaires, the Station’s connecting elements feature STARLED-64 LED floodlight luminaires mounted onto columns along the exterior stairs and ramps.

The optical efficiency of the DALI controlled ENDURALUX LED luminaires and specific mounting arrangement was carefully modelled, revealing improvements by approximately 30% in output, and reducing the burden on power supply requirements. The uniform design approach was specifically aimed at providing patrons with a clear view for the full 160m length along the platforms and facilitating high grade CCTV coverage, significantly minimising both contrast and blind spots respectively. The technical benefits to the Client include reduced long term operating costs that are realised through lower energy consumption and the extending working life well beyond the 50,000 hours life expectancy limit.

The design achieves a minimum illuminance of 150 lux on the platforms and through the overpass, and 42 lux on connecting elements. The LED solution mitigates the requirement for annual lamp replacement that would otherwise be expected from conventional T5 fluorescent luminaires. This is relatively important in a rail environment from an operational perspective as OH&S procedures require overhead high voltage lines to be shut down for maintenance activity. This is both inconvenient and costly and generally undertaken outside of normal hours. Major maintenance activity with the LED solution will only be necessary every 10+ years. This positively impacts on operational and maintenance costs.
