A railroad car float or rail barge is a specialised form of lighter[1] with railway tracks mounted on its deck used to move rolling stock across water obstacles, or to locations they could not otherwise go. An unpowered barge, it is towed by a tugboat or pushed by a towboat.

This is distinguished from a train ferry, which is self-powered.
