Santa Special is a magazine story.
Thomas is bringing some children to Sodor's big store to meet Santa Claus, but a fire had occurred and caused the store to close. The manager will not be able to re-open the grotto in time for Christmas, but the Fat Controller announces that he will arrive at the station tomorrow. Workmen begin decorating an old shed and Thomas is chosen to take the Santa Special to the new railway grotto. He later pulls the afternoon mail train and it starts snowing. On his way back, Thomas passes a snowy cottage covered in decorations and lights. This gives Thomas an idea and with Sir Topham's permission, he is soon covered in decorations and lights for his Santa Special.
