The Blue Line is a line of the Minecart Rapid Transit (MRT) transit system. It was the first line to be added to the system. It serves the northwestern, northern, and southeastern portions of the map. It has an interchange with the Yellow Line at multiple stations, as they run one on top of the other between Spawn Station (B13) and Miningstone Station (B16).
The Blue Line is the longest of the four MRT lines, with 29 stations. The two termini are Gund Valley on the north end (B1) and Cactusville on the south end (B29). The original Blue Line terminated at Nanthaven Station (B28), which still exists, however is no longer the terminus. The new terminus station of Cactusville was unveiled on October 31, 2012.
In Spawn Station, the Blue Line is located on the subground level, below ground level and above the Red Line.
