TheHunter railcars (J sets),[1] are a class ofdiesel multiple unit (DMU) operated bySydney Trains on theHunter Line inNew South Wales,Australia. Built byUGL Rail between November 2006 and September 2007, they initially operated forCityRail. The railcars have received only one refurbishment in their years of service. This changed their livery fromCityRail, toNSW TrainLink.[2]
In 2001, theGovernment of New South Wales called for tenders for seven two-carriage railcar sets to replace the remaining620/720 railcars onHunter Line services, with a contract awarded toGoninan in 2002.[3][4][5]
Each set comprises two powered cars with one having a toilet.[2] The first set entered service on 23 November 2006, operating a small number ofNewcastle toTelarah services on Thursday and Fridays only.[6] The second set entered service on 8 January 2007 also operating a limited number of services. By September 2007, all seven had entered service.[7] They operate services fromNewcastle toDungog andScone alongside the Endeavours.
All sets passed fromCityRail toNSW TrainLink with the Hunter line services in July 2013. In 2014/15, they received refurbished seats, improved toilet facilities, anti-graffiti interior paint and NSW TrainLink vinyls.[8]
The design of the J sets is derived from theTranswa Prospector and AvonLink - the major difference being the driving cars are each single-engined instead of dual-engined, due to the lower top speed requirement for the Hunter line. Reversible seating is covered with durable, vandal proofwoollen moquette fabric in 3x2 formation, and have retractable footrests. CCTV is installed. The cars have been fitted withDellner SPcouplers. They are able to absorb the impact of a collision, and theanti-climbers will also reduce the force of impact. They also have a different body design. Instead of the entire body being of the same design, such as theTangara, the driver's cab is built as a protective cage, made of fibreglass, which stretches to the end of the guard's door. The stainless steel paneling starts at the guard's door. The guard's door is designed to operate separately from the passenger doors.
The trains have multiple-unit capability with the earlierEndeavour andXplorers, but only in the event of failure or for empty coaching stock movements. These cars normally operate as two-car sets, however during peak periods they can operate as four-car sets.
Each car is powered by aCummins QSK19-R diesel engine rated at 559 kW (750 hp) at 1800rpm coupled to aVoith T312bre hydraulic transmission driving both axles on one bogie via Voith SK-485 final drives. An auxiliary 150 kW (201 hp) Cummins 6ISBe-G1 diesel engine drives a Newage Stamford UCI274H alternator to supply power for the air conditioning and lighting.[9] Hunter Railcars are capable of 160 km/h (99 mph) but in service are limited to a maximum of 145 km/h (90 mph).[10]
