Plans for the Olympic Park Line were begun after Sydney won the rights to host the 2000 Olympic games in 1993. The games were to be held on a former military and industrial site in Homebush Bay, which had an existing freight rail line. This line would be eventually converted into the Olympic Park Line, served by a single station: Olympic Park Station.
Trains to the station today are mainly shuttle services, running every 20 minutes on weekdays and 10 minutes on weekends, stopping at Lidcombe Station (on a dedicated “Sprint Platform”, nominally Platform Zero) and Olympic Park Station. During major events, additional trains will also go to Olympic Park Station from Central. There are also a few interurban trains from the Blue Mountains that go into Central Station which then go to Olympic Park Station before dead running to the Flemington stabling yards to be parked during the off-peak.
Olympic Park Station is unique in that it has 2 platforms for each train, with passengers on the train alighting on one platform and other passengers boarding from the other platform on the other side of the train. This prevents any conflicting movements of passengers getting both on and off at the same time, reducing dwell times and allowing a more efficient movement of passengers. This was particularly useful during the Olympics, during which huge numbers of people had to be moved to and from the Olympic Park all day. However, this function has been rarely used since the Olympics (if all at).
Next week: The Airport Line.
