The project “Knot Pilsen, 1st construction – reconstruction of Prague head” is one of the elements of the modernisation of the TEN-T network. TŽK is not only a significant national link, but also a transit link from Germany to Slovakia. The aim of the construction is to provide basic parameters of modernised lines including modernisation of communication and signalling equipment and overhead contact lines. The implementation of the project is concentrated in the localities of the passenger station, the Lobzy rail yard and the marshalling station.
