"Locomotive Smurfs" was latter adapted into a comic story in 1991 under the title "Le Petite Train des Schtroumpfs" ("The Little Train of the Smurfs" in English). There are major differences in the comic adaptation from the cartoon original:
- Nat, Sassette, Grandpa, Baby, and Scruple are absent in the comic version.
- Handy called his locomotive a "locomosmurf" ("locomoschtroumpf" in French) instead of "railsmurfer" in the cartoon version.
- The Smurfs riding on the train used it to collect nuts and wood, while in the cartoon version, they used it as a pleasure trip within their forest.
- The Smurfs riding on the train escaped from Gargamel by hiding inside a hill, while in the cartoon version, they simply out-ran him.
- The Smurfs were rescued from Gargamel's clutches by Papa Smurf, while in the cartoon version, they were rescued by Handy.
- After the Smurfs escaped from Gargamel, Papa Smurf brought to Handy the concern that Gargamel will follow the railroad tracks to their village (as humans like Gargamel could not find the village by themselves). He told Papa Smurf that he planned the railroad tracks before hand to not lead to the Smurf Village which is why Gargamel circled around a tree where they start, far away from the Village at the end of the story. In the cartoon version, Gargamel did not consider pursuing the Smurfs back to their village even though the tracks will lead him there. It was not brought up by Papa Smurf or any other Smurf.
- The story ended with Gargamel and Azrael circling the tree following the tracks in the vain attempt to find the Smurf Village, while in the cartoon version, the story ended with Handy building a miniature version of his train for the Smurflings and Baby Smurf.
