Arry and Bert

' Arry and Bert (also known as Iron 'Arry and Iron Bert) are twin diesel engines who work at the smelters and scrapyards of the Sodor Ironworks. They have also been seen frequently working at Ffarquhar Quarry.

Why They're Not Really Useful

 * 1) They're nothing more than stereotypical bullies especially in "Middle Engine" and all they do is stand around not doing a lot, they barely have any interesting characteristics to them.
 * 2) They act like immature idiots who only like to cause trouble and barely seem to get any punishment.
 * 3) It should be noted that they nearly tried to scrap Stepney and were not caught. How worse can they get?
 * 4) Apart from trying to Scrap Stepney, they constantly bully steamers, especially Percy, as shown in the infamous "Middle Engine" from Season 6.
 * 5) They were at their absolute worst in Calling All Engines as they cause so much trouble that they nearly caused the summer to be ruined and they act like jerks.
 * 6) Their personalities only worsened in the CGI Era as the acted like immature idiots and they were shoehorned in episodes as plot devices.

Redeeming Qualities

 * 1) They did end up paying for their bad behavior in "Halloween'', "Percy's New Whistle" and "Thomas And The Stinky Cheese".
 * 2) They were both upset about what happened to Daisy in "Springtime For Diesel" which shows that they're not heartless.
 * 3) Sometimes, they can do good things.
 * 4) Like most of the engines, their designs are neat and fitting.
