Modernising SUNIJ line

The light rail line Utrecht-Nieuwegein-IJsselstein (SUNIJ) has been operational since the 1980s. It is an important rail line that takes travellers to and from Utrecht. Bosch Beton was contracted by Van Ooijen Gouda to supply over 3,000 metres of special retaining walls, 3,000 metres of platform sections and 200 transit shelter foundations for this project.

The regional light rail line, Utrecht-Nieuwegein-IJsselstein (SUNIJ line), is currently being modernised. In early 2021 travellers between IJsselstein/Nieuwegein will be able to travel to P+R Utrecht Science Park without changing trains. The route will use longer trains that have a lowered entrance. Around 23 stops and sections of track need to be modified for this. Main contractor Bam Infra is working with various parties in this sizeable project, including road and rail infra constructor, Van Ooijen Gouda.

Special retaining walls

For this project, Bosch Beton was contracted by Van Ooijen Gouda to supply over 3,000 metres of special retaining walls, 3,000 metres of platform sections and 200 transit shelter foundations. Our Engineering department designed everything and detailed this in 3D. We produced and kept the walls in stock and supplied these ‘just in time’.

According to the timetable, the SUNIJ line should be operational in early 2021.
