The station covers an area of 5,109 m2 (54,990 sq ft). It is 140 m (460 ft) long, 19.24 m (63.1 ft) wide and 17.18 m (56.4 ft) high.[3]
Piano stairs
In April 2011, Xuezelu station became the first station on the Nanjing Metro to feature a set of "musical stairs" leading up connecting the platform and the concourse levels; since then, Muxuyuan has also installed similar stairs.[4] The stairs were alternatively painted white and black like the keys of a piano, and with the aid of sensors on the adjacent wall, would emit pianistic sounds whenever passengers used the stairs. The utilitarian hope was that this unique feature would help attract passengers away from the adjacent escalators and lower their load.[5] The installation of these stairs caused a large number of Nanjing residents to purposely come to the station to experience them, but also inspired other installations in other mainland Chinese cities. However, the eventual wear and tear on the sensors lead to their uninstalling in December 2012.[6]
