The plan for the year 2005 was that the Metro would measure 70km and the total number of stations on all the lines including the planned line D would be 66.

In 1988, the Metro started its operation on its new line called B3 from Smíchovské nádraží to Jinonice. In 1990, the operation of line B2 from Sokolovská to Zápotockého station (today‘s Florenc – Českomoravská) was planned to start. In 1988, the construction of the new line B5 from Jinonice to Zličín started, Depot Hostivař was under construction and station Skalka was being prepared. Line B5 was supposed to open in 1993, but in the end it did not open until one year later. The delay was caused by the lack of city finances. Twenty years ago, there were discussions how to continue the Metro from Fučíkova station (Nádraží Holešovice) to Troja and Severní město. At that time, it was estimated that between the years 1992 and 1993, 2.8 km of tunnels would be dug and the new stations of Barikádníků on Rudé Armády Street (today’s Zenklova) and Bohnice Housing Estate would be open. As we can see, it all turned out differently. During the following five-year period from 1990 to 1994, the plans were not carried out. What was realized according to the plans was line B which was supposed to go as far as today’s Černý most in 1995. However, in the end, there was a four-year delay. 

Preparations of the construction of line D were planned to start as early as 1995. According to the plan, the line was the basis of the circuit. The first part was meant to operate between the stations Jiří z Poděbrad and Mládežnická (today’s Pankrác), possibly to Budějovická. Line D, with 17 stations and 20 km, was planned to be finished in 2005.
