Thomas, who is a ninth-grader (i.e., he’s just 14 or 15 years old), says:

Sydney, my home town, has around 4.7 million people and already has a commuter rail network, however, the city is growing, and the network doesn’t cover everything, so I have augmented the network in many places, as well as showing how it could grow into the currently undeveloped far south- and north-west (they are generally the places where the stations have no names, there simply aren’t currently any for them). It is show by the thick lines. Also represented by the thick lines is the long planned north-west rail link in light green/khaki. Additionally, the map shows bus rapid transitways and light rail in half thickness, some built, some planned, and some I propose. Finally, the map shows the intercity trains as far as the city limits in quarter thickness, as well as an extra express service from the planned Badgerys Creek Airport to the existing Kingsford-Smith airport and the city loop.

Transit Maps says:

Being a native Sydneysider myself, I can’t help but laugh at the sheer audacity of some of Thomas’ proposals for new lines. Yes, it’d be great if there was a rail line running up through the Northern Beaches (from the southern side of the harbour via The Spit, no less!), but the geography of the area means it’ll realistically never happen.

Pipe dreams aside, the map is really quite beautifully drawn, especially for someone so young. His dream system is extremely complex, but everything fits together nicely with a good information hierarchy and harmonious colours. He’s even indicated ferry routes, busways and the extended light rail system to produce a fully multi-modal vision, which is great to see.

This is very promising work from Thomas: keep it up!
