|This article is about the Diesels. You may be looking for the steam engine or the Story Library book.|
In their first appearance, 'Arry and Bert crept alongside a lonely Stepney, who had mysteriously been sent to the smelters by mistake. They shunted Stepney into the larger smelting shed underneath a giant grabber, and threatened to scrap him. Thankfully, Stepney was saved by Sir Topham Hatt, once the diesels had left.
Despite being villainous, 'Arry and Bert are also known for playing tricks on steam engines, such as making them "middle engines". Once, they shunted trucks in front and behind Percy. This later lead Percy to being pushed onto the coal tipper by mistake. Later, 'Arry and Bert played the same trick on James. Sometime later, they frightened Fergus away from the smelters, and bullied Neville, which made the engines think he was planning to bump them.
On some occasions, 'Arry and Bert's teasing ways backfire. Once, they played a ghostly prank on Thomas and Emily during Halloween, though they ran away when they thought Emily was a ghost. Another time, 'Arry and Bert teased Percy for having a whistle. Percy payed them back by creeping up behind them and blowing on his whistle. Later, along with Diesel, 'Arry, and Bert began teasing Thomas for being smelly, but were later covered in stinky cheese.
'Arry and Bert were also part of the group of Diesels that took over the Sodor Steamworks. They later teased Henry because of the coal he had to use by calling him "Mr. Special Steam". They also laughed at Gordon after he ran into Diesel's flatbed and damaged his bufferbeam.
'Arry and Bert are unquestionably devious and scheming. They feel superior to steam engines and, working at the scrap yards, they enjoy the chance to break up engines, or at least make their lives more difficult. Due to their grim task, they have earned a reputation on Sodor as "The Grim Messengers of Doom." However, despite their prejudices, the diesels have co-operated with steam engines on occasions, and when they are in trouble, steam engines often come to the rescue.
Despite being villainous, 'Arry and Bert also have a tendency to act scheming, slimy, greasy, and oozy. According to their merchandise bios, they wish to scrap Oliver and Stepney, who have escaped the cutting torch once before.
'Arry and Bert are BR Class 08 shunters. Over seventy members of this class survive today in preservation. Diesel, The Diesel Shunter, Splatter, Dodge, Paxton, and Sidney are also members of this class.
'Arry and Bert are painted green-grey with yellow hazard stripes on their fronts with yellow cabs. They have "Sodor Ironworks" written on their sides in white.
