Reg works at Crocks Scrap Yard moving and unloading scrap and broken machinery into trucks so engines can take them to the Smelter's Yard.
In Tale of the Brave, he met James who had to collect some trucks of scrap. Reg created a colossal pile of scrap on a flatbed, later nicknamed the Scrap Monster. James used Reg's creation that night to scare Percy.
Diesel once pretended to be Reg in order to hide from Paxton. Reg was confused as to why Paxton was chasing after silly Diesel. During Christmas time, Percy tried to encourage him to cheer up the scrapyard for Christmas, but later discovered that Reg was celebrating Christmas in his own way, by making decorations from the scrap. Later, Reg almost scrapped Sir Topham Hatt's Car because of Samson, but Scruff stopped him just in time.
When Toby ran out of coal at the scrap yards, Reg tried to flag down an engine in order to give the tram engine some coal, but unintentionally made the other engines think he was scrapping Toby by lifting Toby off the rails and using him as the flag.
Reg has a Cockney accent, attitude, and tone. He has a tendency to be sarcastic and loves to crack a joke. He is very confident about who he is and what he does even though he sometimes makes remarks that sound self-deprecating.
Reg's specific basis is unknown. However, Reg resembles a diesel-powered Smith rail mounted crane.
Reg is painted yellow with black warning stripes and has his name painted on his side in brown.
