While the railway network at Port Kembla was built in 1916, stations and passenger trains servicing the surrounding suburbs did not operate until 5 January 1920, when the Port Kembla railway station was opened. A station at was added to the Port Kembla commuter branch in 1926, along with one at , a decade later, in 1936. A railway station for workers at Port Kembla, named , after the nearby Lysaght steel plant, was also opened in 1938. Some platforms on the line (e.g. Scarborough) are only 4 or 6 cars long, so not all doors may open on 8-car trains. Services and rolling stock Services were originally operated with locomotive-hauled trains and, later, Diesel railcars, prior to the electrification of the South Coast railway line. The line was electrified to in 1984, with the suburban Eastern Suburbs & Illawarra Line service occasionally extending its service past the terminus at to Helensburgh during peak hours, a practice that the current Sydney Trains Eastern Suburbs & Illawarra Line service still follows today. Electrification extended to the following year. Despite the newly installed electrification, diesel sets and locomotive-hauled trains still operated along the line from all the way past Wollongong to Sydney, including the South Coast Daylight Express, until 1991. Electrification of the South Coast railway line was further extended to in 1993 and, finally, to Kiama in 2001. The railway between Kiama and is the only part of the line that remains non-electrified, operated by New South Wales Endeavour railcars since their introduction in 1994. The electrified rolling stock of the South Coast Line began with V set intercity trains. There were later accompanied by Tangaras when they were introduced into the CityRail network in 1988. Originally, the Tangaras that ran on the South Coast Line were different variations of T sets known as G sets. G sets differed from T sets in that they had reversible seats, toilets, fresh water dispensers and luggage racks. In late 2005, it was discovered that a majority of the V set rolling stock operating on the South Coast Line were suffering from corrosion in their underframes. More G sets were introduced onto the South Coast Line to compensate, and eventually became the standard rolling stock on the South Coast Line after V sets ceased operating on the service. From January 2012, V sets ceased operating South Coast services. In 2009, however, after the introduction
