The brand-new train depot holds space for parking trains, five repair spots, wash bay, service and staff rooms. Seventeen parking spaces for trains are located at the end of a 320-meter-long concrete tunnel under Eriksbergsåsen. While the repair and office spaces are located in a facility above ground.
For the entry tunnel, Oglaend System designed and supplied a custom-made framework of Mekano® channels in HDG. This system facilitates for combining all disciplines in the same system. It was installed directly onto the rock bolts in these underground tunnels.
“Our rock bolts could not hold the tolerances they were supposed to and they were crooked, so we got a fixing from Oglaend System that made it all straight, and then we could use a traditional central support system,” Peder Oreskär from NCC explains.
Indispensable flexibility
“We chose Oglaend System primarily because it is a flexible system that is easy to modify or supplement later on. We had strict demands regarding tolerances and load capacity when we installed the system that will be beneficial in the future,” Fredrik Landstorp, SL project manager says.
Several challenges such as; tall ceiling, uneven surface and a humid environment had to be considered when choosing the right support system for this project. Due to these challenges it was important that Oglaend System could facilitate for unforeseen modifications.
“When we had to make some modifications, we did not have to get a smith to weld and do the reconstruction work. We also got help with picking the right products that suited our project,” Peder Oreskär from NCC says.
Upgrade works on The Red line
The new depot was constructed as a part of the upgrade works on The Red line to provide improved capacity. There are about half a million travellers on this line every day. A new depot and new trains help ensure more frequent departures and better comfort for the travellers.
