Construction on Changchun Light Rail Line 4 started in April 2009. The line includes 16 stations and has a total length of around 16 kilometres.
Rail dampers have been installed to reduce the N&V impact on residential buildings, hospitals and schools in the section along Linhe Street. Measurements show vibration mitigation even at frequencies between 31.5Hz and 80Hz.
