Question: The Northfield railway line formerly brought meat out of the abattoirs from which suburb north of Adelaide?
Context: Gepps Cross (pronounced 'Jepps Cross') is a suburb and major road intersection in the north of Adelaide, South Australia.  Gepps Cross is traditionally seen as the end of the inner suburbs and the start of the outer northern suburbs, as it was home to a major abattoir (now closed) with holding yards and other open space.  It is the first significant open space encountered after the North Parklands.  It retains the open nature, even with warehouses, a velodrome, hockey stadium, Adelaide Raiders – a Croatian soccer club and karate training facilities. Wingfield is a suburb situated north of Adelaide.  It lies between the Port River Expressway on the north and Grand Junction Road on the south.  The suburb borders Dry Creek to its north and east, bounded by the Gawler railway line and Adelaide-Port Augusta railway line on the east.  The North-South Motorway and Dry Creek-Port Adelaide railway line both cross the suburb.  Wingfield is named after R. W. Wingfield, the private secretary to Governor of South Australia, William Jervois. Palmerstown is a south-eastern suburb of Barry in the Vale of Glamorgan south-west of Dinas Powys and 7 miles south-west of Cardiff in Wales.  It is immediately north of chemical and plastics industries such as Dow Corning, and Barry No.2 dock and the Atlantic Trading Estate lie south of the suburb.  Its south end is separated from the A4055 Cardiff-Barry main road via Palmerston Road, ("sic") a tee junction with the A4055 and access to the original part of Palmerston's housing is via a narrow railway bridge over the Barry-Cardiff railway line and lies north-west of the former Biglis Junction which was a short distance from the so-called "Palmerston Bridge".  Immediately south-east of the railway line lies a Waitrose supermarket and fuel station which took over the former Safeway business in 2004 and prior to that, the site housed J.Feltz, Sidroy Mills lingerie factory.  Separated from the area and south east of the railway is Tŷ Verlon trading estate.  Schools and other establishments within its boundary do not include the letter 'w' in the name, as is the case shown for the inset picture header on this webpage.  Palmerston includes the local Glenbrook Inn established in 1982 and to the west of the suburb was the colloquially named “Penny ha’penny” footbridge, which being about 550 feet long, linked Palmerston with the Coldbrook area of Cadoxton.  It bridged 39 railway sidings known in railway terms as “Cadoxton North Sidings” and following the complete closure of the Cadoxton-Pontypridd/Penrhos Railway line after 1963, it survived for a while after all the railway sidings were lifted.  An extensive housing estate now sits on the sidings area. The Halesowen Railway, also known as the Halesowen and Northfield Railway and the Halesowen Joint Railway, was a standard gauge railway in what is now the West Midlands of England.  It connected the Great Western Railway's branch from Old Hill to Halesowen (opened 1878) with the Midland Railway’s Birmingham to Gloucester line at Longbridge Junction (formerly known as Halesowen Junction) near the present Longbridge station.  The term "Halesowen Railway" is sometimes applied to the whole line between Old Hill and Longbridge but, strictly, it applies only to the portion south of Halesowen. Northfield railway station serves the Northfield area of Birmingham, England.  It is situated on the Cross-City Line.  The station, and all trains serving it, are operated by London Midland. The Carlingford railway line is a minor railway line in Sydney, Australia.  Opened in 1888, the line runs north-south between the suburb of Carlingford and the Main Suburban railway line at .  Passenger services on the line form part of the Sydney Trains commuter rail network and are marketed as the T6 Carlingford Line.  The railway line's small catchment, low patronage, short platforms and single track for much of its length mean the T6 generally operates as a shuttle service, with passengers changing at Clyde for T1 North Shore, Northern & Western Line services to the Sydney central business district and Parramatta.  Most of the line is planned for conversion to light rail as part of the Parramatta Light Rail network.  As a result, the line will permanently close. Strathfield is a suburb in the Inner West of Sydney, Australia.  It is located 12 kilometres west of the Sydney central business district and is the administrative centre of the Strathfield Local Government Area.  A small section of the suburb north of the railway line sits in the local government area of the City of Canada Bay, while the area east of The Boulevard sits within the Burwood Council.  North Strathfield and Strathfield South are separate suburbs, to the north and south respectively. The Chaokai Railway (朝开铁路, "Cháokāi Tiělù") is a 58.4 km freight-only railway line of the China Railway in Jilin Province, China, connecting Chaoyangchuan on the Changtu Railway with Kaishantun.  The line formerly crossed the Tumen River to reach Sambong in modern-day North Korea, but the bridge has since had the tracks removed, and is in use as a road crossing. The Esashi Line (江差線 , Esashi-sen ) is a Japanese railway line formerly operated by Hokkaido Railway Company (JR Hokkaido).  It connected Goryōkaku (near Hakodate) and Esashi . The Northfield railway line was a railway in northern Adelaide.  The line branched east from the Gawler line just north of Dry Creek station.  In earlier years, it saw mixed freight including livestock in and meat out of the Gepps Cross abattoirs and sale yards.  In its later years, it was operated as part of the metropolitan passenger rail network and served three stations: Cavan, Pooraka, and Northfield.
