The choo choo
service in Sydney, Australia and other surrounding intercity areas. It is a rail system that has been building since 1855 and now is (not so) complete with 302 bin-less, terrorist targeted stations each connected by 2,060 km of shoty ladder laid down on dirt; naming it "one of the most complex commuter rail systems in the world", hence the most unreliable. In 2006, CityRail run 12 different types of double decked rail car, in which only 2 of those run on a day-to-day basis because they are simply just too tired.
The service is also sometimes referred to by friendly commuters that are late to work everyday as ShityRail
