These coaches are four-wheeled coaches on the Skarloey Railway.
Since Sir Handel insulted the coaches, they do not trust him, even when he tries his best to be kind towards them. They are considered to be awkward and rude. They bumped Sir Handel off the rails when he had to stop suddenly to avoid running over a flock of sheep. Skarloey scolded the coaches severely, and had to pull Sir Handel's train instead.
Peter Sam found a scrapped coach, and it was later restored into The Tea Room. Later, Rusty took the Sodor Brass Band around a tour on Skarloey Railway using one of these coaches. On Mrs. Percival's birthday, Mr. Percival arranged for Sir Handel to take them to the lake.
