The Logging Locos (Thomas & Friends)

The Logging Locos are a group of American logging engines from Thomas & Friends who live and work on Misty Island. The group is made up of Bash and Dash, two tank engine twins, and Ferdinand, a climax tender engine.

They first appeared in the feature length film Misty Island Rescue. Bash and Dash last appeared in the season 16 episode "The Christmas Tree Express" and did not appear again, while Ferdinand was reduced to cameo appearances after season 16.

Overall

 * 1) They're very annoying and one-dimensional characters who serve no purpose to the series other than for comic-relief. By the way, they are unfunny comic-relief characters.
 * 2) They have the exact same personality to each other, which is no personality. This is further proven with how Bash and Dash have the same design, just with their colors switched.
 * 3) They are one of the main things that sped up the series’ decline in quality during its first dark age (seasons 9-16) and are also one of the main reasons why “Misty Island Rescue” was poorly received.

Bash and Dash

 * 1) They do nothing but say each other’s lines from start to finish.
 * 2) Their voices in the UK dub are awful as they are incredibly high pitched and irritating.

Ferdinand

 * 1) To get the elephant out of the room, his catchphrase "That's right!" is very annoying and repetitive. Granted, it's common for characters to have catchphrases, but Ferdinand's catchphrase is overused to the point where it gets very annoying to listen to. And to make things worse, he said "That's right" for a total of 20 times. That will most likely get on your last nerves.
 * 2) Besides his annoying catchphrase, he doesn't have many lines compared to Bash and Dash.
 * 3) While he has a nice design, his face can be uncanny to look.

Redeeming Qualities

 * 1) At least they helped Thomas get back to Sodor and complete its Search and Rescue Centre.
 * 2) They're now learning how to be Really Useful engines on The Fat Controller's railway by helping the Sodor engines and learn about the proper way of doing things, the values of good behavior and forming new friendships with others.
 * 3) Their designs do look interesting and are pretty good.
 * 4) They have decent voices, thanks to William Hope, Kerry Shale, Glenn Wrage (US) and Ben Small (UK) voicing them.
 * 5) The only time they were likable was in season 15’s Toby and Bash, which was a mediocre episode.
 * 6) Thankfully, they were written out of the series after season 16 due to their negative reception, though Ferdinand only made a cameo in one episode of Season 18 without any reason.
