In this article for Eurotransport, Ondřej Krulikovský, Head of Service of Buildings and Tracks at Prague Public Transit Company (DPP), describes the standard maintenance work that takes place on Prague Metro’s rail superstructure, which encompasses ongoing renewal and improvement to the track system. He explains the key activities that take place during the downtime period – between 1:10 and 3:50 a.m. – which include the re placement of wooden sleepers with those of concrete, restoration of freestanding fastenings and systemic rail grinding.

t is the DPP’s Service of Buildings and Tracks department that ensures the management of the rail superstructure, the tunnels and other constructions within the metro in Prague. In total we maintain 61 stations, 31.27km of tracks in tunnels with sleeper fastenings, and 99.44km of tracks with freestanding fastenings. In tunnels, we take care of 40 switches in gravel beds and 64 switches with freestanding fastenings. There are a further 161 of such switches in three depots. We also maintain three test tracks with a total length of 5.2km and one siding, which connects the Kačerov depot to the railway network. We spend approximately CZK 210,000,000 annually on the maintenance of the rail superstructure, the tunnels and other structures.
