PROBLEM TO BE SOLVED: To easily realize switching of a rail line shape.SOLUTION: A system for switching a rail line shape is used to switch the rail line shape of a rail 3 installed on a bed plate 2 between first and second lines L1 and L2. The system comprises: a PC construction girder 10 supporting the rail 3 under the rail 3 of the first line L1; a PCa widening girder 20 provided adjacent to the PC construction girder 10 in the rail width direction and supporting the rail 3 under the rail 3 of the second line L2; a connection mechanism 30 for connecting the PC construction girder 10 and the PCa widening girder 20 to each other; and a rail fastening device fixed to the PC construction girder 10 and capable of fastening the rails 3 of the first and second lines L1 and L2. In such a system for switching the line shape, the line shape of the rail 3 can be switched between the first and second lines L1 and L2 by moving the rail 3 along the rail width direction between on the PC construction girder 10 and on the PCa widening girder 20. |
