Thomas Saves the Day is a magazine story, illustrated using photographs from the television series.
It is a sunny day on the Island of Sodor, but no-one has time to enjoy as everyone is very busy, especially Thomas. A new station is being built and Thomas has to ferry workmen to and from the building site. Thomas is looking forward to the grand opening.
Suddenly, Thomas sees some runaway trucks heading towards him on the next track. The trucks are out of control and going much too fast, heading towards the new station. Thomas gives chase and alerts the signalman who quickly changes the points. The trucks hurtle into a siding. Nobody is hurt and the new station is safe. The stationmaster is very pleased with Thomas for saving his new station. Thomas feels like a hero and a really useful engine.
