Jason is an elderly tender engine who lives at Kahlville Junction.
Jason is kindly, rough and ready, and Jebediah's old friend. A former worker of the old Inkblotia Money and Coin Co. Factory until it closed down in the 1930's, he's now working at the Din Y. Dee Gold Mine Transfer Yard on the outskirts of Cliffstone with Fearless Freddie running the narrow gauge branch to and from the mine, transporting gold ore to the Gold Smelters in Rotoslopia. But he still helps his old friend Jebediah with the Milk Train, and also takes passengers, mainly through the Cliffstone branch lines. He and Freddie keep things running smoothly along these mountain tracks, However, Jason can come off as a daredevil grandpa sometimes.
Jason is of a freelance design. Therefore, he's not based on a specific prototype. However, Jason may loosely be based on the White Pass & Yukon Railroad's #52, Which was built in 1881 by the Brooks Locomotive Works for the Utah and Northern Railroad. It was bought by the White Pass In 1898 as the railroad's first locomotive.
Jason is painted pine green with a red and yellow nameplate and gold lettering on the tender.
- Jason originated as a faceless and nameless locomotive from a classic Ducktales episode called Back To The Klondike.
