Design of the “Metro” urban rail network according to a 1926 design by the engineers Vladimír List and Bohumil Belada. An underground railway was in the minds of Prague’s residents for a long time. The first proposal for an underground railway in Prague was presented by Ladislav Rott in 1898, the construction work was to be connected to the construction of the sewerage system and the redevelopment of the Old Town. The first proposal for the building of four underground lines was submitted in 1926. The construction of the first line, the A line, started just before the war, but history did not favour the metro. After the war, work was supposed to resume, but the country, recovering from the devastating conflict, was not strong enough economically.
