Bash and Dash are fun loving steam engine twins from Misty Island.
Bash, Dash, and Ferdinand worked on The Other Railway for a few years before Mr. Charleston eventually got tired of their behavior and sent them to Misty Island, so that the mainland could get jobi wood. They were eventually forgotten when jobi wood was no longer needed.
Bash and Dash are mischievous twins who always finish each other's sentences. They were sent to Misty Island along with Ferdinand to help build the railway so the Mainland would have an easier way of getting Jobi wood. They always try to do their best for the Sir Topham Hatt.
