Shaft, station changes for Copenhagen

摘要

Design development for next phase of Copenhagen metro has cut the number of shafts and resulted in shallower construction at some stations.rnThe client, Metroselskabet, said that it has been decided to drop 15 shafts - three-quarters of the initial total -from the 15km long, twin bore Cityringen project. It said that safety for the metro system would be improved by technology, such as installing sprinklers in trains, and that fewer shafts meant less disruption from construction traffic.rnThree of the project's 17 stations are to constructed at shallower levels than usual in the Danish capital's metro system, and the possibility of raising a fourth is being investigated. In earlier planning, most stations had platforms at approximately 18m-19m below the surface, and the deepest sites at 24m and 28.5m,rnrespectively.
