Jim crow (tool)
A jim crow is a tool for bending rails, consisting of a U-shaped or V-shaped armature with a hefty screw rod in its axis. Deluxe models are outfitted with rollers for continuous bending.[1]

Practice
Railway rails are quite flexible and bend easily to radii of 400m or more. The jim crow is needed to bend rails to tighter radii, especially near the ends.
