Introduction phases, reconstruction of Bp.-Lyug. and design woods of the order of construction and surroundings, the construction of the plan for construction at Liszt Ferenc International Airport. Woods of the planned railway development are the Bp.-Nyug. pu. bev., which are used by most commuters, the trains are crowded at peak times, the flights can no longer be condensed due to the constraints of the current infrastructure. In accordance with the BAVS, if the planned tunnel between Kelenföld-Bp.-Pyug. is built, the aim of the development is to ensure the operation of up to 20-20 trains per hour and direction on the common course. Necessary capacity increase: Bp.-Nyug.-D.keszi-Production plant, examination of the need for the Kap.bőv. (no. 4 vg) for new traffic vgs, in accordance with the Bp.-Nyug. It’s a stone-Kispest stretch. According to the BAVS, it is necessary to complete the construction of the Marcheggi bridge, Káposztmegyer, Városliget, Törökőr mh. and the replacement of Istvántelek mh. The content of the design tree is the complete reconstruction of the listed sections and the service places, as well as the replacement of the level crossings with special level road and cycling and walking structures. The preparations for the development of the R.palota-Újpest station and the exact location of the branching of R.palota-Újpest (cf.

Fa. preparation of all necessary plans for the construction and obtaining of a permit, including environmental protection parts, tender design and construction tender documentation. The tender plan also includes the construction plan for passenger, high-end and landscape architecture. Carrying out full authorisation and obtaining the necessary management, operator, ownership and other approvals is part of the project. The design task includes: —27,6 lines re-construction of vg. and overhead contact line, —construction of the surface network of Bp.-Nyug. pu., connection to the railway tunnel detailed in the BAVS, -7 complex re-construction on public utilities, construction of -4 new railway mh.
