PROBLEM TO BE SOLVED: To perform various operations quickly for parts along a vehicle rail in a railroad station. SOLUTION: This movable prefabricated scaffolding includes an assembly carriage 20 and an assembly work vehicle 40, where the assembly carriage 20 has two traveling frameworks 21, 22 having two supports 25, 26 provided with wheels 23, 24 rolling on respective vehicle rails 11, 12; horizontal support beams 27 for fixing the supports 25, 26; braces connecting the traveling frameworks separately in a direction along the vehicle rails 11, 12; and floor boards placed on the horizontal support beams 27 of the two traveling frameworks 21, 22. On the supports 25, 26 of the traveling frameworks 21, 22, two guide rails 39 are mounted, overlapping a platform 10 so that the assembly work vehicle 40 can be delivered onto the guide rails 39 from the platform 10.
