DPP plans to replace a total of 510 wooden sleepers with concrete ones during this autumn’s closure. It will work in two places – on the 2nd track directly in the Vyšehrad station and in the line tunnel on the 1st track between the IP Pavlova and Muzeum stations. In addition, workers in both sections will also replace the original rails with new ones. There are a total of 6,359 sleepers in this section, of which more than a quarter (1,774) are already new concrete sleepers. Replacing sleepers is a long-term thing, DPP usually uses Easter for it, the beginning of the summer holidays and the autumn days off.
