Grontmij, together with Sweco, has been awarded several extensive consultancy contracts for the planned City Line in Stockholm. Contracts have been awarded both in the first stage including preliminary design of the two stations and also in the final stage with final design of one of the stations and part of the tunnel.

City Line is a double-track railway with two new stations that is to be built in a 6 kilometre-long rock tunnel between the commuter station Odenplan and Stockholm Syd. The City Line is being constructed in order to solve the capacity problem for rail traffic through Stockholm. The project is a long-term solution to the congestion problem. The City Line will double the capacity of train services through central Stockholm.
