The project 'Citybanan', is a railroad project in Stockholm with a 6 km commuter train tunnel with two commuter train stations under the existing subway stations - a multi-billion project that opened and opened for traffic in the summer of 2017.
Grandezza has had several consultants involved in the project, both at the Swedish Transport Agency as planned and built the facility and at the Traffic Administration within the County Council, which received the completed stations and is responsible for the operator who operates the Citybanan.
