ABSTRACT:
A re-railing unit for re-railing a derailed rail car comprises a base, two stabilizer rams located at opposite ends of the base, and a port plate slidably mounted on the base. The support plate carries a pair of vertical lifting rams from which is suspended a vertical lifting arm. The bottom of the lifting arm is hook-shaped to engage the underside of a rail car drawhead. The lifting arm raises an end of the rail car in response to extension of the lifting rams. A shifting ram then slides the support plate across the base to reposition the rail car wheels over the track. The lifting arm is lowered to enable the wheels to rest upon the track.
