InterCity XPT Power Car

The unveiling of the Express Passenger Train (XPT) at Commonwealth Engineering's Sydney plant in August 1981 heralded the dawn of a new era for both Australian passenger train concepts and locomotive technology. The train came about following many year's procrastination as to what kind of conveyance would best serve NSW's country train travellers.

Comeng successfully tendered an Australianised version of the tried and proven British Intercity 125 High Speed Train (HST) concept, which provided locomotives at both ends - one pulling and the other pushing. State Rail, impressed by what they saw, initially ordered ten locomotives (to be offically known as 'power cars') and twenty matched coaching vehicles.

Because Australian operating conditions were vastly different to those experienced in Britain, the XPT was virtually redesigned from the bogies up. Australia's generous loading gauge allowed for longer, wider and higher passenger cars and while the British HST version was constructed of welded steel, the Comeng version used the stainless variety.

The XPT was equipped with the same Paxman 'Valenta' 12 cyl. RP200L four-stroke turbocharged engine as employed in the British HST, but was de-rated to 1491 kW to suit Australia's hotter ambient temperature. The traction gear was reduced slightly to provide a 1000 lb (4.1 kW) greater maximum tractive effort to enable the train to negotiate lengthy steep gradients (such as the 1 in 33's experienced on the Blue Mountains route).

Over the years, the XPT locomotives (and carriages) have undergone tremendous change to better equip them for their seemingly constant task. According to the XPT Maintenance Centre, almost 150 detail changes have been carried out on the locomotives' engines and traction equipment and many of the improvements have been exported back to England. They include modified load regulation characteristics in respect of alternators and traction motors to increase the allowable current to those motors for starting and low speed operations.
