Norway’s Vestfold Line: Track Doubling & Modernization
October 28, 2019 10:47 am



This article delves into a significant railway infrastructure project undertaken by Bane NOR (Norwegian National Rail Administration), the state-owned railway company of Norway. The focus is on the substantial investment in track doubling along the Vestfold mainline, a crucial artery connecting Oslo and the surrounding regions. This project, encompassing two major contracts awarded to different consortia, represents a substantial commitment to improving railway capacity, efficiency, and passenger experience. The analysis will examine the scope of work, the awarded contracts, the technological implications, and the long-term benefits for the Norwegian railway network. The project’s complexity, involving extensive earthworks, tunnel construction, and bridge building, highlights the challenges and opportunities presented by modern railway modernization initiatives. Furthermore, the article will explore the strategic significance of this investment within the broader context of Norway’s national transportation plan and its commitment to sustainable and efficient public transport.

Vestfold Mainline Track Doubling: Contract Awards and Scope

Bane NOR awarded two substantial contracts for the doubling of tracks along the Vestfold mainline, a key railway corridor in Norway. The combined value of these contracts totaled NOK 5.62 billion (approximately $613 million USD). The first contract, valued at NOK 3.66 billion, was awarded to a joint venture comprising Salini Impregilo and Impresa Pizzarotti. This contract encompassed a 13.6 km stretch of track between Nykirke and Barkåberg, south of Holmestrand and north of Tønsberg respectively. This section included the construction of two bridges, the new Skoppum station (located 1.3 km southwest of the existing station), and three tunnels with a combined length of 5.3 km. This represents a significant undertaking in terms of earthworks and complex infrastructure development. The second contract, awarded to Veidekke Entreprenør for NOK 1.96 billion, focused on the construction of a 6 km rock tunnel between Drammen and Kobbervikdalen. This illustrates the varied challenges in upgrading this critical railway line.

Technological Advancements and Infrastructure Upgrades

The track doubling project on the Vestfold mainline isn’t solely about increasing track capacity. It also necessitates significant upgrades in signaling and control systems to ensure safe and efficient operation of the increased train frequency. While not explicitly detailed in the initial contract announcements, the successful integration of advanced signaling technology, such as European Train Control System (ETCS), would be crucial for maximizing the benefits of the track doubling. The project’s success hinges on seamless coordination between the track infrastructure and the signaling and train control systems. The integration of modern technologies is critical for enhancing safety, optimizing train scheduling and maximizing the throughput of the railway line.

Capacity Enhancements and Improved Passenger Experience

The primary objective of the Vestfold mainline track doubling is to significantly increase its capacity. Upon completion (scheduled for the end of 2024), the line will boast continuous double tracks between Drammen and Tønsberg. This enhancement is expected to more than double the line’s capacity, enabling the operation of two trains per hour in each direction between Oslo and Tønsberg. This will directly translate to improved passenger service frequency, reduced journey times, and a more reliable and efficient commuting experience for passengers using the Vestfoldbanen. The increase in service frequency addresses a key constraint in the existing system, improving the overall attractiveness of rail travel.

Economic and Societal Impacts

The investment in the Vestfold mainline track doubling extends beyond simply enhancing the railway network. It represents a substantial contribution to Norway’s overall economic growth. The project generated numerous jobs during construction, supporting local economies. Beyond the immediate economic effects, the improved transport links facilitate better connectivity between Oslo and the surrounding regions, which is beneficial for commerce, tourism, and residential development. The increased railway capacity reduces reliance on road transportation, potentially leading to decreased traffic congestion and improved air quality, contributing positively to the environmental sustainability goals of the region.

Conclusion

The Bane NOR initiative to double the tracks on the Vestfold mainline is a significant investment in Norway’s railway infrastructure. The awarding of two substantial contracts to experienced consortia, focusing on both extensive earthworks and tunnel construction, showcases the commitment to upgrading a key transport artery. The project’s scope, encompassing the construction of tunnels, bridges, and a new station, illustrates the complexity of modern railway infrastructure development. Beyond the immediate construction phase, the long-term impact will be substantial. The increase in capacity, enabled by the track doubling, will significantly improve the efficiency and reliability of the Vestfoldbanen, offering passengers a more convenient and efficient rail service. The integration of advanced signaling and control systems will be paramount for safe and efficient operations of the increased train frequency. The project’s success represents a crucial step towards bolstering Norway’s commitment to sustainable and efficient public transportation, fostering economic growth, and improving the quality of life for commuters. The project serves as a model for other countries seeking to modernize their railway networks and enhance their transportation systems for a more sustainable and efficient future. The success of this project will likely influence future infrastructure investments across the country and inspire similar ambitious upgrades elsewhere.
