Eureka's steam era W44 features the first dedicated ore carrier, the GC. This was a subclass of the G wagon, introduced in 1951.W44 ran as a block train of sixteen wagons, with a loaded weight of 1020 tons, hauled by two AD60 class Garratts between Molong and Orange, then a single Garratt to Lithgow, and two 46 class over the Blue Mountains. As N645, it continued to Gosford, where a 36 and a Garratt took over for the final run to Cockle Creek.
