Cactus has been asked to develop and deliver a CTC (centralised traffic control) system for the extension and upgrading of the Haparanda Line in accordance with the ERTMS standard. The job was the biggest railway order ever for Cactus. The end customer was the Swedish Transport Administration, and Cactus was a sub-contractor to Ansaldo STS Sweden.
The order carried great potential for the future, as the Swedish railway network is to be progressively modernised in line with ERTMS Level 2. At present, there are firm plans up to 2035.
The system for the Haparanda line comes under Level 2. System development takes place in accordance with the Swedish Transport Administration’s standard and SS-EN 50 128.
The procurement is part of the Swedish Transport Administration’s ERTMS project, which is responsible for finding two suitable suppliers of ERTMS Level 2 systems for the Swedish market.
The Haparanda line runs between Boden in northern Sweden and the Finnish border. The line thus connects the Finnish and Russian railway networks with the Swedish and Norwegian networks.
The Swedish government originally commissioned the Swedish Transport Administration to upgrade the existing line between Boden and Kalix, and also to build a brand new railway line between Kalix and Haparanda, due to a higher flow of goods with increasingly long and heavy train sets for steel, mining and containers.
The new Haparanda line will be electrified and equipped with a modern new signalling system. Work on the upgrade began in 2006. The Haparanda line was re-opened in 2013. The total cost is estimated at SEK 3.3 billion.
The Cactus Traffic Management System is a reliable turnkey system with a virtually unlimited capacity. It is designed to be customised and comprises several modules:
In the 1990s, the EU decided to develop a common standard for rail traffic management. The new standard is called the European Rail Traffic Management System (ERTMS). The aim is to adapt all railways within the EU/EEA to ERTMS. ERTMS has three levels.
