The metro in Prague consists of three different lines marked with letters A, B and C. They are represented by three colors on the indicators and maps: line a green, line B yellow and line C red. There are 54 stations in total, linked by more than 50 kilometres of mainly underground trains. You can see all lines and stations on metro lines map or on a map with the tram system. The metro service runs in between 5 am and midnight every day, with around 2-3 minutes in between trains throughout heavy traffic. Over 420 million travelers use the Prague metro every year.
All three lines of the metro system fulfill in the centre of the city, forming a triangle with three transfer stations (Muzeum, Mustek and Florenc). The depth of the stations differs significantly. The inmost station is NamestiMiru, situated 52 meters under the surface. The stations in the city centre on lines A and B were mainly tired utilizing the tunneling guard and they are for that reason situated quite deep. External parts of these lines and practically entire line C were dug by the cut-and-cover technique so the stations are just a few meters under the ground. The B line partially runs inside a glassed-in tunnel above the ground: in between the stations Hurka and Luziny in the western part and in between Rajskazahrada and Cerny Many in the east. The line C in between I.P.Pavlova and Vysehrad crosses a valley inside a 40 metres high road bridge.
The majority of the cut-and-cover stations have a single platform in the centre of the station hall serving both instructions. They usually have straight ceiling often supported by columns. The deep-level stations are typically formed from three tunnels: The bigger main aisle with the track tunnels on each side. The Prague metro is an open ticket system. Travelers are required to confirm a ticket and buy prior to getting in the metro platform. There are general ticket checkers who can examine the credibility of the ticket at any time within the required ticket area.
