📋 Tender Overview
A series of test drives at a speed of 200 km h took place in the Ejpovice tunnel between Pilsen and Rokycany. Their main purpose was to gain practical knowledge about the behavior of the traction system in a long single-track tunnel at this speed. The test runs were preceded by measurements by diagnostic means of the Railway Administration and a technical safety test was performed which confirmed the suitability of the relevant line section for journeys at 200 km h.The Ejpovice tunnel was built with the help of a punching shield with a smaller diameter a fixed carriageway was built in its tubes. In an environment where the set is a piston the traction line behaves differently than in a double-track tunnel or on a wide track. Due to the fact that the method of construction of the Ejpovice tunnel proved to be highly effective its use in the design and construction of new railway tunnels is assumed. The actual test runs were carried out with a special measuring set BB consisting of two traction vehicles of the 1116 Taurus series equipped with a measuring pantograph between which a car for diagnostics of the traction line was placed.The measuring set reached a speed of 200 km h in four runs exactly as planned. We will further analyze the diagnostic data obtained during the test runs and use them for the optimal design of traction line structures when introducing higher speeds on the lines of the Railway Administration said Ji Svoboda General Manager of the Railway Administration. Currently 207 kilometers of various track sections are being prepared on which speeds of up to 200 km h could be driven in the future.These include in particular the 15.5-kilometer-long section between Chocn and Uhersk where it should be possible to drive at a speed of 200 km h from mid-2025. eight kilometers of line between Sobslav and Doub again from the beginning of 2026.A part of the new line between Pilsen and Domalice will then be designed for a speed of 200 km h the trains on the new building between Brno and Perov or between Nemanice and evtn will reach the same speed. The Railway Administration is also preparing adjustments for the necessary speed increase on the Beclav - akvice line where test runs took place this year.
