I agree buses would be a start , but when I see comments like "forget about building railways/metro's stations, all we need are buses" I think about the logistic, Someboby said you would need about 60 buses ? Well you would also need 60 drivers , a place to park them when not in use ie a depot , with mechanics , cleaners and fuelers ! And if you think well just get Stagecoach or First bus can do , well maybe on a Sunday but any other time nearly all there fleet will be in service , Stagecoach, First or any other bus company will have 60 buses hanging around doing nothing .
