Illawarra Junction
The Illawarra Junction is a major railway junction located near the Eveleigh Railway Workshops, in the inner western suburbs of Sydney, New South Wales, Australia. This complex junction joins a number of different lines and yards. There are two pairs of tracks (named Illawara Main and Illawara Local) from the Illawarra railway line from the south and three pairs of tracks (named Local, Suburban and Main) from the Main Suburban railway line from the west. Arrangement. Illawara Line. The first set of junctions is in the south-west corner, just north of Erskineville station, where trains coming from  the Illawara line can dive into the Eastern Suburbs line. Further north is the Illawara Dive, where trains from the Illawara Main can crossover to the Main without obstructing any of the other tracks. This dive is mostly used by weekday off-peak South Coast Line trains terminating at Sydney Terminal (Central platforms 1–12), services on the Southern Highlands Line or NSW TrainLink Southern regional services. East of Redfern station there are no further crossovers with the lines continuing toward the flying junctions at Central. On either side of the Illawara Main, there are connections (with no track) to the  disused platforms 13–14 at Redfern. Main Suburban Line. In the north-west corner, just north of Macdonaltown station, there are a number of crossovers allowing trains to switch between the Local, Suburban and Main lines. These crossovers are seldom used. Just past the end of the entry/exit track for Macdonaldtown Yard are two crossovers between the Local and Illawara Local tracks, allowing trains from the Illawara Local to access Sydney Terminal. There is also a disused track from the Eveleigh Railway Workshops connecting to the Up Main. East of Redfern station is where the Main Suburban line ends. There  are a complex set of flat junctions allowing trains on all three pairs of tracks to enter Sydney Terminal. The local and suburban tracks also continue on the City Circle and North Shore line respectively. Eveleigh Maintenance Centre. Eveleigh Maintenance Centre lies to the south of all the surface tracks and on top of the Eastern Suburbs line tunnels. There are several crossovers providing access to the yard. There is a crossover in the south-west corner, allowing trains from the Up & Down Illawara Main to access the yard. Another crossover allows trains to access the Down Illawara Dive, which  is actually bi-directional, due to the crossover at the other end onto the Up Illawara Dive. Trains from Sydney Yard can enter/exit through the Engine Dive, which passes from the Down Main, under Redfern station, to the yard. Trains to/from the City Circle can enter through the Arrival/Departure Road, which joins the Up/Down Illawara Main. Macdonaltown Yard (not shown on map). Macdonaldtown Yard lies between the Main Suburban and Illawara lines. It has a single entry/exit road. Crossovers allow trains to enter the yard from the Up/Down Local lines and allow trains to  exit the yard onto the Up Local or Up Illawara Local lines. Signalling. Previously controlled by the Sydney Signal Box (near Central Station), this area is now controlled by the Rail Operations Centre in .
