PROBLEM TO BE SOLVED: To reduce cost for the whole of the equipment, improve the conveyance by decreasing the size and weight and save labor in work. SOLUTION: A main body 1 of correction equipment is made drivable along a pair of left rail 101 at reference side and right rail 102 at correction side laid on the foundation ground. The main body 1 of the equipment is equipped with various kinds of mechanisms 20, 30, 40, 50 or the like on the drive frame 2 for the purpose of correcting track alignment. The drive frame 2 is formed to one united body with one main frame 3 and a pair of left and right sub- frames 5, 6 provided on both right and left end portions of the main frame and extended on rail respectively. A front to rear width W1 of the main frame is made narrower than the front to rear width W2 of both the right and left sub-frames thereby limiting the width within the region H in plan for not projecting out the W1 from the total length L of the drive frame and the front to rear width of both the sub-frames, and various kinds of mechanisms and tools such as handle for track alignment correction are installed and loaded in that region.
