Designed as a site specific light art installation for the Vivid Sydney Light Festival in 2011, (B)right on Time autonomously responds to the movement of trains at Circular Quay. As trains pull in and out of the station, trigger sensors initiate a pulsating lighting sequence in the public area underneath the rail bridge. Dynamic coloured light references the colour of the rail line of each train, with the sounds of the trains above adding to the multi-sensory experience.
The site for the installation incorporates approximately 80 metres of public thoroughfare, commencing at George Street and running parallel to Alfred Street, to the station precinct of Circular Quay Station.
In simplest terms, the control of lights was coordinated to the City Rail timetable, with each train triggering the lights as it passed into or out of the station. City Rail operates a train approximately every 2-3 minutes in peak hour, so the frequency of light operation was regular and fairly consistent, particularly during peak hours.
The light colour also changed to reflect the different train lines; orange lighting for the Bankstown Line, purple lighting for the Inner West Line, green for the Airport and East Hills line and blue for the South Line.
The (B)right On Time installation was a popular installation during Vivid Sydney 2011 and revived the underused area beneath the rail bridge, to become a destination and feature of the Circular Quay precinct.
