This puts the tally of Sydney tram fires at six since February. The CBD and South East light rail lines are operated by the ALTRAC Light Rail consortium, comprising Transdev and Alstom, in a “public-private partnership” with the NSW government. The Office of Transport Safety Investigations (OTSI), the state transport investigator, published an “Interim Factual Statement” on July 14. Grech declared after the March 5 fire that “without immediate action, there’s a real risk to commuters and light rail workers.” Through rank-and-file committees, politically independent from the union bureaucracies and Labor, Sydney light rail workers can link up with broader sections of workers, across Australia and internationally.
