Mr. Rails

Mr. Rails is an old guy who works at the International Underground and a close colleague of Ernie.

Source Material Background
Mr. Rails was the loco mechanic of the International Underground from the British television series Underground Ernie. Besides working on mechanical stuff such as the trains, he also doubled as the janitor of pretty much all stations on the rail system because they apparently didn't have any other employees to take care of the Underground besides three and was pulled into all other sorts of oddjobs despite being in his 60's, the poor bastard.

R.O.T.F.M. History
Just like in the show he comes from, Mr. Rails is the general caretaker of the International Underground and has also even been called onto doing other tasks from other organizations, much like Mr. Bixby. In fact, Mr. Rails is very good friends with Mr. Bixby, have thus have went out on many swagster adventures. One of which being the time when they helped organize a very special event taking place at the Shoehorn County fairgrounds. Mr. Rails has also been known as one of the sexiest old guys alive within the entire realm, appearing on the front page on the magazines 5 times in a row, and is also often associated with Never Had a Dream Come True by S Club 7 whenever he appears as a guest star at special events, especially when he appears in his naughty dragon costume. He is also a champion of the Cool Dance Competitions despite being his age and has won in 1st to 2nd place on multiple occasions.

Role in Viva Nut Alien, DDS
Mr. Rails appears in the show as a regular supporting character towards Glenn, Dinko, Phil, and Fergy. He once helped fix Glenn's RV when it broke down but conveniently did so next to one of the International Underground railway lines and also helped restore the silly engine for Tito Dick's surprise birthday train in the episode The Dickman Express.
