Ribbed Base-Plate Rail Fastenings in Pictures By F.A. Wingler, March 2001

The bearing ribbed base-plate for rail fastenings had been designed in Germany by the engineer Döhlert and introduced on German Railway in 1926. It is the most successful base-plate for indirect rail fastenings on wooden-, steel-, concrete-, composite-, polymer sleepers and ballast-less slab tracks around the globe. The KPO fastening from 1926 on wooden sleepers superseded the direct and indirect dog-, cut- and screw-spike fastenings and had become the conventional rail-fastening in most Central and East European countries, in Central Asia and as well in Turkey for wooden sleepers. Together with an epsilon shaped elastic tension clamp, SKl (“Spann Klemme”, patented 1967 by the German Engineer Professor Hermann Meier at the TU Munich and manufactured for the world market by Vossloh, Germany) it entered also India as a standard elastic fastening for Metro Rail on concrete plinth tracks and for modern turnouts.
