Mid-month theme: Subway day

Sydney's extensive rail network constantly receives bad press: the service is not frequent enough; trains run out of order or late; the fares are too high; and, the carriages are not clean enough. While acknowleging these issues, my intent is to describe the past and the present of the rail system. Here is the style of diagram with which many of you will be familiar.
The CityRail Network Map provides a detailed view of the above diagram. I live close to the City and I will post mainly, but not exclusively, about city stations which appear on the right centre of the diagram in a loop known as City Circle.

City Stations Central Town Hall Wynyard Circular Quay St James Museum Martin Place Kings Cross

Suburban Lines Eastern Suburbs & Illawarra Bankstown Inner West Cumberland Airport & East Hills Southern Line North Shore & Western Line Northern Line Carlingford Line Epping Line

The mid-month Subway theme has contributions from the following cities:
