Once, the Sodor River Bridge was rebuilt. Stanley transported workmen to and from the construction site, Rocky assisted in building the bridge, while Thomas transported the specially made bricks. During Thomas' last trip to the site, his brakes became faulty and he lost most of the bricks when he ran across a bend at high speed and crashed into some buffers. Thomas' brakes had completely broke by the time he had reached the bridge, and he almost ran straight off it, losing the last of the bricks in the process. Thomas, Stanley, Rockey and Murdoch went back along the route Thomas' had taken and were able to find all the lost bricks, allowing the River Bridge to be completed by the end of that day.
The bridge has five archs and is double tracked.
