Biography
Before being brought to "Bertram's Station", Class 40 was sent to Sodor in 1962 to assist the engines with goods and express work toward the end of Stepney's visit, but he only insulted the other engines by saying they were out-of-date, should be scrapped and bragged about his modernity. He got his comeuppance when an inspector's bowler hat jammed in his air intake, causing him to break down and to become as sick as boiler sludge. He sulked in the shed while Duck and Stepney took the Express for him.

While everyone was fare-welling Stepney, a disgraced Class 40 crept away, leaving behind "a rather nasty smell of bad manners and a battered bowler hat".

In 2015,he was brought to Bertram's station, after six nights, he and the other engines were crushed by a landslide. After that, they were possessed by Stanley. Class 40 had been unpossessed by Smudger later on.
