Arry and Bert are two diesel shunters that currently work at The Sodor Ironworks but they are sometimes barrowed to shunt empty trucks at the smelters yard.


Arry and Bert were built at Doncaster Works in 1965 and were bought by the Sodor Ironworks to assist with shunting and small iron trains all around the island. The Twins where rather devious and sometimes tried to nick incoming locomotives that were ether lost or needed tune-ups and scrap them as Stepney found out one time.

Later the two teased Derek about his troublesome engine. But the tables turned when Bert broke down on the mainline while double heading with Arry.


Arry and Bert are devious and scheming. They have a dislike to steam engines but sometimes have grown accustomed to them as well.
