Kazan Metro-<span>is a </span>rapid-transit<span> system that serves the city of </span>Kazan<span>, </span>Republic of Tatarstan<span>, </span>Russia<span>. The metro system was the seventh opened in Russia, and the fifteenth in the former Soviet Union region. Opened on August 27, 2005, it is the newest system in Russia.
</span>The first stage of six stations would feature deep level tunnels all built by tunnel boring machines<span>and for the stations to be either sub-surface or elevated. Little of the original Soviet station plans was left in the architecture of the stations, with emphasis on traditional Tatar and Islamic motifs as well as modern high-tech designs. The first shield arrived in Kazan at the end of 1999 and was launched in May 2000.
</span>Initially, the pace was slow and the financial problems were about to prevent the construction to be completed on time. In a desperate attempt, in late 2003 the Russian Ministry of Transport ordered metro brigades from Samara and Moscow to assist and the first stage was made one station shorter, leaving the difficult path under the Kazanka River to open at latter time. Another contribution was made by the Almaty<span>Metro construction brigade from </span>Kazakhstan<span>. Thus, by the late 2004, a total of eight tunnel boring mechanisms were in operation. On the whole a total of thirteen individual tunnels had to be bored.</span>
