after a number of breakdowns soon after opening, it was decided to retain drivers, who occupied the first car of each train. Rolling stock Delivered in 1987, six trains of seven carriages were built by Von Roll Holding to the Type III specification. Each seated 48 passengers, with the driver occupying the leading carriage. (They were designed to seat 56, using all seven carriages.) The first was displayed at the Trans Public Show in Geneva, Switzerland in May 1987. The monorail trains ran on rubber wheels, and each seven-car train had six traction motors, permitting a normal operating speed of . The doors of each car were automatic, and the floor level was self-adjusting via an automatic suspension system. Each train was long, wide, and high. Set 1 was stored following a significant collision between it and Set 4 in early 2010. The last carriage in Set 1 was removed from the set, and used to replace the damaged last carriage in Set 4. When operations ceased in June 2013, sets 2 - 6 were operational. Stations The monorail operated in a single anticlockwise loop with stops at the following stations (in order): Maintenance and control facilities The six monorail units were maintained in a purpose-built facility in Pyrmont. A traverser allowed monorail cars to be removed from the main track for maintenance or stabling. Maintenance of track and stations was conducted at night with two special vehicles, named 'Buggy' and 'Mule'. The facility also housed the control room (located above the maintenance area), as well as administration and staff amenities. Criticism The decision to build the monorail over other forms of rail such as light rail was in the eyes of many a political decision. Light rail would have been $20 million cheaper to build, serviced more passengers per hour and cost 40% less for a ticket, but the monorail system prevailed. The city of Sydney formerly had a tram system that was in operation from 1861 until 1961. Incidents On Thursday 28 July 1988, an electrical fault caused the system to cease operating. Fifty passengers were stranded in carriages for two hours between 3:50 - 5:50 pm. TNT Harbourlink was criticised for failing to call emergency services until 5:40 - by the time the fire brigade arrived at the scene, the passengers were en route to disembarking at a station. In July 1992, monorail services were suspended due
