how to reduce noise
enhancement of lubricator and rail turnout
- To reduce the friction sound of train wheel and rail, auto oil lubricator is installed and to minimize the compact sound, gap in frog of rail turnout needs to be minimized.

rail head part and train wheel turning
- the noise to happen during the train operation can be minimized by cutting the side of rail and the side of train wheel cleanly.

Line 4 train runway and car management
- the noise which can happen during the train operation can be minimized by concrete runway management, motor car rubber wheel management(erosion, air pressure), connecting passage and door sound proof system management
