Bergen Light Rail

Bergen Overview

• Bybanen = light rail:

• Bybanen Utbygging = light rail development

• Bergen dumped trams at sea in 1950’s, when rail lines were closed in Ireland

Tram in operation in Bergen City Strong public uptake Providing an alternative to the Car

Bybanen = light rail

Bybanen Utbygging = light rail development

Overall Bybanen Layout

• 5 stages

• 1 & 2 operational

• 3 Mott MacDonald

• 4 & 5 future

• Mountainous terrain means linear urban development

• Vision: 80% of workplaces and 50 % of homes within 600m of a stop.

Bergen Light Rail

Optimisation Stage

• Optimisation exercise a contract obligation:

• Line: 50 optimisation points

• Depot: 25 optimisation points

• Each optimisation point to provide analysis and assessment of functionality, , overall strategy for implementation, risk factors, cost & programme reductions

• Decision Papers

• During optimisation and detailed design

• Identify issue

• Determine options, costs, programme, functionality pro’s and con’s,

• Make a recommendation

• Rastolen example

• Line optimisation report:

• 68 optimisation points

• 27 decision papers (optimisation stage)

• Depot optimisation report

• 25 optimisation points

• 50 decision papers

Construction Progress

........MMD has produced a fantastic

3d model which runs through a very

complex terrain. From what i have

seen on other projects, this is

maybe the most complete and

advanced infrastructure model you

can find today.......

.......A lot of the

things MMD has done in this project

with 3d models will probably set a

benchmark for how things, are

presented in 3d in future

infrastructure projects in Norway.
