Construction of a huge railway tunnel & station in the heart of the historic city of Delft


Originally awarded in 2007, the vast ‘Spoorzone (Rail Zone) Delft’ project is hugely ambitious, involving the construction of a rail tunnel directly under the historic city of Delft. 
The major challenge was building underground, whilst respecting historic monuments and maintaining a good cooperation between the community, client and contractor.
In 2015, the project reached an important milestone when DIMCO completed the first phase of the 2,400 m ‘Willem van Oranje’ rail tunnel, which opened on schedule.
Initially the tunnel has opened with two completed rail tracks and under Phase 2, which has already got underway, two more rail tracks will be added. The second phase is due to be completed in 2018. 

An underground station and parking area was also completed in 2015.
