The Shiftworkers

A GROUP of shiftworkers at a power station all start work at the same time in the evening. They all travel together to the nearest railway station to their work, and because of the time of night, transport between the railway and the power station is provided. Each night at the same time, their supervisor (an all-round nice guy) leaves the power station in a mini-bus and goes to the train station to collect his workers.

One night, the train arrived ahead of schedule, so the workers decided to walk towards the power station. It was half an hour later when the supervisor met the workers on the road and picked them up. They turned around and drove to the power station and arrived at work sixteen minutes early. What a shock that was to their systems!

How many minutes early did their train arrive at the railway station?
