Abstract
A method of and arrangement for correcting the height of a railway upper structure with a reinforced concrete plate thereon into which plate a reinforced concrete part as support for rail holding members is so inserted that the reinforced concrete part is positioned above a just finished or poured concrete section of the reinforced concrete plate in conformity with its end position and is subsequently lowered and jarred into the not yet hardened concrete of the reinforced concrete plate. For purposes of carrying out such height correction, first the finished part is disconnected from the supporting plate by detaching the bolts which interconnect the supporting plate and the finished part from each other and subsequently lifting the finished part, to which the rail holding members are connected by separate bolts, together with the rail section pertaining thereto by a distance required for the desired correction as a result of which a space or cavity is created between the finished part and the supporting plate. This space or cavity is then filled with a filler, and subsequently the finished part is again firmly connected to the supporting plate by means of bolts.
