Blue Cat Blues Tom

Blue Cat Blues Tom

An episode of Tom and Jerry ended with both characters sitting on a railroad track waiting for a train, but this was not the final episode of the series.

A common claim about the classic cartoon Tom and Jerry holds that the final episode of the series ended with both characters committing suicide:

This theory likely stemmed from, or at least was popularised by, a list published by Cracked in August 2012, which included an episode of Tom and Jerry called “Blue Cat Blues.”
After recapping the events of the episode, stating that the show fades to black while Tom and Jerry sit on the railroad tracks as a train whistle blows, the author wonders if this is the last episode of the series:

This episode was produced during the initial run of Tom and Jerry, dubbed the “Hanna Barbera era” after producers William Hanna and Joseph Barbera, which lasted from 1940 until 1958. The final episode in this run was called “Tot Watchers,” which was released on 1 August 1958, nearly two years after “Blue Cat Blues,” and didn’t feature Tom or Jerry committing suicide. (It did, in a slightly less dark turn, feature the characters being taken away by Animal Control for stealing a baby.)

Furthermore, slapstick violence was a signature mark of Tom and Jerry cartoons. While “Blue Cat Blues” certainly hit on darker themes than other episodes in the series, Tom and Jerry survived explosions, burns, falling anvils, misplaced rakes, and even gunshot wounds:
