The Stockholm City Line (Swedish: Citybanan) is a railway tunnel under construction beneath central Stockholm in Sweden which will be used by the Stockholm Commuter Rail. The line will be 6 kilometres (3.7 mi) long, double track and electrified. It will have two stations: Stockholm City Station will be located directly below T-C2012_08_01_9002entralen, the central station of the Stockholm Metro. The Odenplan station will be the other station, and will be located next to the Odenplan metro station. The line is scheduled to enter service in 2017.

Construction management of the 2 northerly Contracts required very challenging and modern rock excavatio n methods. A 150m long and up to 15 m deep wire sawed and blasted open cut to the portal was not only the first of its kind, the total cost of the specialised method resulted in a lower total cost of the construction. Wire sawed shafts and slots at Odenplan were other essential and challenging new technologies that were applied on the project. Cutting through the centre of Stockholm the project encountered many vibration sensitive passages e.g. Medical research labs, 17th – 18th century buildings and churches. Extremely challenging but highly entertaining project to have the pleasure of being part of.
