Sir Reginald is an express engine who lives at Kahlville Junction.
A very fast steam engine originating from France, Sir Reginald is the express engine between Gridinia Bay Junction and Celgreb Bay Harbour. He's a little snooty at times, but is far more polite than Spencer and Farnsworth! He's helpful, very quick to the point, and is willing to do freight runs...a job other express engines are known to hate!
Sir Reginald appears to be based on a Royal Hudson from the Canadian Pacific Railway.
Sir Reginald is painted navy blue with yellow stripes.
- Sir Reginald was based on a navy blue steam engine that made a cameo in the Madeline special, Madeline and the Gypsies.
