The Challenges

A new tramline is currently being built commissioned by the Rotterdam The Hague Metropolitan Area. The new line will connect the MCH Antoniushove hospital in Leidschendam-Voorburg via Delft Central Station with a new development area ‘Technopolis’ in Delft. The part of the route from Delft Central Station to the tail track in the Technopolis area has been engineered by Royal HaskoningDHV and runs through the historic centre of Delft.

Tramlijn 19 in Delft | Royal HaskoningDHV

Our Solution

Construction of the route starts at the point where Tramline 19 connects with Tramline 1 at Westvest, Delft. The line continues over the Zuidwal, a historic and monumental part of the city centre. This section crosses an arched bridge and bicycle tunnel. From the connection with Tramline 1 until the end of the Zuidwal, the tramline mixes with other traffic. The Zuiderpoort marks the beginning of a free lane for the tram. The design of the free lane involves a redesign of the existing infrastructure, including the main route for motorised traffic.

The Outcome 

Redevelopment of the infrastructure has had a large impact on the underground infrastructure (cables and pipes).

Royal HaskoningDHV's assignment includes:

  • Engineering of the main sewage system
  • Connecting the rain water drainage systems
  • Creating a detailed time table including an implementation programme
  • Composing permit requests
  • Calculating cost estimates
  • Doing research, such as determining the environmental state of the soil
  • Designing road and railway in 3D (using MX)
  • Designing catenary system
  • Engineering civil structures (bridges, tunnels etc.)

The existing draft design has been worked up into a final design in close consultation with the client. Changed insights led to several adjustments of the design. This included a redesign of the draft which were used by the client and the municipality to make several choices about the route.
