During the repairs it was required to restore the paint coating of step frames, to replace the part of additional runners of the escalators and 100% of the flooring, rig and riser. There was no need identified to restore the geometry stage of the step, the framework elements, semi-axial seats for any step. The entire batch of 1518 steps has been returned to service after repairs.
