The most frustrating part of public transport journeys is the wait between services. This is especially a problem during off-peak times. Many of the world’s big cities have train services with frequent services all day (every 10 minutes or better), making public transport attractive at all times of day, and helping to spread the peak load. Well-run systems also have buses which collect people from surrounding areas and then meet the train at the station (fancy that!). By comparison, waits of 30 minutes to 1 hour for buses are common in Melbourne, and station car parks fill up by morning peak hour.
