Processing the 8.8 km long Grakallbane in Trondheim, Norway.
In May last year, Jumbotec received a contract that extended far beyond the northern border of Germany. Extensive tamping and leveling work on the tram line in Trondheim, Norway, was to be carried out for the client Boreal Bane AS.
The Grakallbane is the northernmost tram line in the world, which opened on July 18, 1924, with the first 5.7 km. It was later extended to a total length of 8.8 km. For this project, JumboTec enlisted two strong partners: Bahnbau Wels and IngVeBa. Bahnbau Wels supported with their ballast leveling machine PBR 205 while the surveying office IngVeBa took over the track surveying and marked the entire route.
Norway is not a member of the EU, making the import procedures for machines, spare parts, and all accessories more complex than usual. JumboTec was able to demonstrate its competence in handling international assignments by easily overcoming these bureaucratic hurdles. Thanks to close coordination in advance with the client Borel Bane AS, work successfully began in July. JumboTec used the narrow-gauge tamping machine type Plasser & Theurer 08-75 /4ZW for the tamping work.
After tracking in Munkvoll – Trondheim, the machine crew started the tamping work. Over a period of three weeks, the entire route was processed, and the initial contract for the client Borel Bane AS was successfully completed.
By executing this project, the Rhomberg Sersa Rail Group proved that through cross-company collaboration, we can offer a complete package for their customers in narrow-gauge technology and deliver excellent tamping performance beyond the borders of Germany. In addition to technical capability, the versatility and readiness of the staff were crucial to the success of this unique project.
