Sydney Central's Flying Junctions - Explained!

On the southern approach to the suburban platforms at Sydney's Central station, is an ingenious piece of infrastructure known as 'the flying junctions' or simply 'the flyovers.' It was built as part of the original suburban electrification scheme in 1926, and allowed trains coming in from the suburbs to cross over to any of the suburban platforms without conflicting with trains travelling in the opposite direction. The layout was changed slightly in the year 2000 when the newly constructed Sydney Airport line was cut in half way along the structure. This slightly reduced the usability of the layout, but it is still an incredibly useful feature which allows a huge amount of flexibility in the case of disruptions.

Corrections:
In the video I mention that Up Airport trains can access Platform 23. A few people more knowledgeable than myself have pointed out they can also access Platform 22.
