The Frieght Cars of the Dock Railway are used for transporting coal, quary rocks, bricks, sand and wood. Like their counterparts in the Thomas & Friends series, they are quite troublesome and like causing mischief. Their antics inculde singing rude songs, name calling, holding back, shoving and bumping. They have been the cause of many acidents.
- So far, they are the only rail-based models to have faces.
- There models are the same as the the Season 1 Troublesome Trucks from Thomas & Friends.
- Due to the fact that many of the acidents they cause result in their destruction, the Frieght Cars have been considered to be suicidal.
- They have cousins, the boxcars, who are often less troublesome than they are.
