Initially all testing is taking place at night, although Transport for New South Wales (TfNSW) says it expects daytime testing to begin within the next few months.
The 12km line will run from Circular Quay with Central Station, Surry Hills Moore Park, Kensington, Kingsford, and Randwick. It will serve Sydney cricket ground, Sydney football stadium, Randwick racecourse, the University of NSW, and Prince of Wales Hospital in Randwick.
The 19-station line will have capacity to carry 13,500 passengers per hour, with services operating at four-minute intervals between 07.00 and 19.00.
As a member of the Altrac Light Rail Consortium, Alstom is supplying 60 of the 33m-long LRVs, which will operate in pairs, together with its APS ground power supply system for a 1.6km section of the route, 750V dc overhead electrification, a Hesop energy recovery system, and depot equipment.
Alstom will also be responsible for maintenance of the line and the LRV fleet.
