This is a handy dandy GUI mod for the public transportation interface. It adds list views for bus, metro and train, toggleable visibility of all lines (including public transportation lines and hides the transportation lines of other types while you are looking at one type.
Extends the public transport UI with additional list views and toggles for bus, metro and train. Nicely integrates with the native UI. Just press the bus, metro or train panel in the public transport panel to bring up the extended UI.
