My curiosity also led me to google plans for an underground railway in Brisbane. I learnt one independent group has already prepared a proposal document. The proposed route map is here. The proposal document cites London's Central Line and Dockland Light Railways (DLR) among examples of several options for the different system to be considered. The less said about the DLR, the better. Basically, it's an ugly light railway system augmented with some new tunnels and viaducts. But like all light railways it reeks of compromise. The Central Line, a deep-level tube line more than 100 years old, is fantastic, and perhaps my favourite on the Underground. Its east-west axis cuts across London in next to no time, and its 1992 rollingstock is fresh and modern.

Whatever subway is chosen in Brisbane, we can be sure that it won't be as susceptible to failure as the UK's rail network. I don't know whether the infrastructure is just old, or the rail companies staffed with whingers, but it's a well-known fact that trains stop running in London for the most absurd reasons. In autumn, it's "leaves on the tracks" (apparently tree leaves get wet, and turn into a slippery mush). In winter, it's "snow on the tracks". And in spring and summer, the tracks warm up, and bend, and the trains can't run, causing the mass panic we saw last week when the system shut down. And yet, everyone knows that in other countries there are leaves, and snow, and hot weather, but this problem remains peculiar to England...
