A railroad track lifting an aligning frame particularly for operation in switches has a rail engaging sub frame extending transversely of the main frame of a tamping machine. The sub frame has two members connected for relative adjustment transversely of the main frame in a telescoping fashion. A rail contacting element is provided on each member and abuts the inside of the rail of the track. A jack is provided to adjust and maintain the relative position of the members transversely of the main frame of the machine so as to adjust the track gauge spacing between the rail contacting elements. A pair of substantially vertically extending rail guides, one for each rail of the track are provided as is a device for moving the guides transversely of the main frame in the sub frame. Rail hooks are provided for each guide means which rail hooks externally engage each rail of the track. A track lifting jack is provided for each rail and is connected on the one hand to the main frame of the machine and on the other hand to one of the rail hooks. A track aligning jack is operatively connected between the main frame of the machine and the sub frame. |
