Green track
Railway trackbed planted with grass or other vegetation / From Wikipedia, the free encyclopedia
Green track (also grassed track or lawn track) is a type of railway track in which the track bed and surrounding area are planted with grass turf or other vegetation as ground cover.[1] It is a popular way of making railways more visually appealing,[1][2]: 10 particularly for trams and light rail, and providing additional urban green space.[3]: 15–16 Aside from the visual improvement, the vegetation provides a number of positive effects, such as noise reduction,[4] less air pollution,[5] rainwater runoff mitigation,[6][7] and reduced urban heat island effect.[3]: 14–15 [8][7]
