Metro network is the backbone of the public transport system of any large city and, from this point of view, a further development of this system is a substantial question and one of the priorities. The current Metro network in Prague consists of three lines: A, B and C, with 53 stations and the total line length of approximately 54 km. There is a dedicated depot for each line (in Hostivar, Zlicin and Kacerov). One of the primarily monitored construction projects in the Metro network is currently the extension of Metro's A line westwards. Given the overall extent of the project, it is envisaged that the project will be divided into stages: - The operation section of the A line, from Dejvicka to Motol; the newly considered extension westwards to the area of the Petriny housing estate and to the Motol Teaching Hospital; operation length of 6.0 km, 4 stations. If required, this operation section can be flexibly shortened so that it will terminate at Petriny. (operation length of 4.5 km, 3 stations), - The continuing operation section Motol - Prague Ruzyne Airport (the north branch), operation length of approximately 7 km, 4 stations. A study work is currently in progress to check the construction and technical feasibility of the route designed in this way (the penetration through the Prague Ruzyne Airport in the lane of railway transport, new station layout, etc.). The implementation of this route, if any, directly depends on how it will be actually needed in relation to the transport from and to Prague Ruzyne by rail, - South branch Motol - Zlicin, operation length of 5.0 km, 3 stations. The Motol - Bila hora section is identical with the route of the above-mentioned north branch of the line, further continuing to the Repy housing estate and the Zlicin station (approximately 3.8 km). In this regard, the line can be branched at Bila hora. This south branch is only viewed as a prospective development of the Metro network in this quadrant of the city.
