Chairman

The Chairman is an executive elected by a company's board of directors who is responsible for presiding over board or committee meetings. They often set the agenda and has significant sway as to how the board votes.

During the corse of the series the Chairman is seen as the Head of the railway and everything has to go through his point of view before any decisions could be taken place.

He has a small office nearby the station, where he and Cars see about the day's events and who is on what jobs for each day.
