“Bust my buffers!"
- "I think you have.”
- ―Bill and Ben
- Buffer Bother is the twentieth episode of the sixth series.
Bill and Ben have been working hard in the Clay Pits. One day, the Fat Controller comes to inspect the quarry's engines, he discovers Derek and Bill are in satisfactory condition, but finds that Ben's buffers are damaged and the Fat Controller sends him to the Steamworks to have replacement buffers fitted. Bill, jealous of Ben, tells Ben that he only needs new buffers because he is clumsy and the two argue. Derek scolds them for being grouchy and Bill goes back to work while Ben leaves.
Bill, still thinking of Ben's new buffers, becomes careless, causing him to knock a pipe into his funnel and sneeze it out. He tries thinking about birds, trees and anything that might make him forget about Ben's new buffers, but it is no use. Derek tells him to be happy that he is in working order (and not in need of new buffers), but Bill simply huffs and wheeshes soot all over Derek by accident.
When the trucks overhear that Bill is cross about Ben getting new buffers, they start teasing him, making him crosser still. Bill tries to stop the trucks from their teasing by bumping them, but accidentally reverses into a ditch and damages his buffers in the process. Ben arrives from the works with a new pair of shiny buffers and sees his twin's predicament. When Edward arrives with Judy and Jerome to rescue Bill, the Fat Controller scolds him for his misbehaviour. Derek tells the Fat Controller that Bill said he was sorry for thinking about Ben's buffers. The Fat Controller agrees and and tells Bill that he must learn how it is important to be responsible and reliable before he can get new buffers when he gets to the Steamworks.
Once back on the rails, Bill compliments his twin on his new buffers and the two properly make up for their quarrel.
