High-speed rail link Helsinki-Turku; general plan for Espoo-Salo direct rail line

• Finnish Transport Agency, 2018-
• The high-speed rail link between Helsinki and Turku is a remarkable project both regionally and nationally. It will increase commuting and have an impact, for example, on the business environment and the competitiveness of companies as well as land use and housing production.
• The Helsinki-Turku project can be divided into four parts: the Espoo urban railway line, Espoo-Salo direct rail line, Salo-Turku double track and Turku railway yards.
• The aim of the project is to prepare a broadly accepted general plan for the Espoo-Salo direct rail line.
• Proxion is involved in the project as an expert in modelling as well as railway and geotechnical engineering.

• Finnish Transport Agency, 2018
• Proxion was responsible for earthing system design for the railway bridges and other special structures between Pasila and Helsinki.
• The aim of the project was to design the earthing system for an old railway bridge to meet the requirements of the electrified railways.
• The work required extensive knowledge of railway bridge earthing and an analysis of the particular type of site.
• Our designers ensured that the earthing system will meet the requirements of the electrified railways.

In addition, design work included lighting for the northern underpass extension, Haarakallio bridge lighting, switch heating and lighting for the new switches on the additional western track as well as disconnector cabling.

• Finnish Transport Agency, 2017
• In cooperation with the Finnish Transport Agency and Solita, Proxion carried out a study regarding the generation of machine-readable train route data through the existing signalling systems.
• In the future, the data will be needed as the management of railway network capacity and conflict resolution become automated, enabling more efficient use of the railways.
• Proxion’s solution combines signalling system expertise with the use of the ProVISU system, offering an effective way to create a digital twin of interlocking functions.

Improvement of coastal rail line in Jeppas area, railway plan

• Finnish Transport Agency, 2017- (ongoing project)
• The aim of the project is to prepare a railway plan, in compliance with the Rail Tracks Act, for the improvement of the kilometre section 38+400-40+440 between Kirkkonummi and Turku, including the improvement of stability on soft ground, rearrangement of drainage systems and removal of a level crossing, including alternative traffic and road arrangements.
• The project includes road, street and railway infrastructure planning as well as signalling system, railway electrification and high-voltage engineering.

Vuosaari Harbour

• Port Of Helsinki 2017-2018
• Construction of rails for the pulp terminal
• Construction of warning systems for several level crossings
• A functionality study of rail transport throughout the harbour. A comprehensive compilation of transport-related observations was collected from those using the rails. Based on the observations, it was possible to offer proposals for improving both the existing systems and current operational models.

• Finnish Transport Agency, 2016-2017
• The project area includes 16 traffic operating points. The railway section is approx. 110 km long and has two tracks for the entire distance with the exception of the triple track section between Sääksjärvi and Tampere. Proxion was responsible for the Riihimäki-Vinnilä section (part 1).
• The aim of the project is to ensure smooth operations on the main line and improve its usability.
• The project included signalling system design.

HELRA – Helsinki railway yard

• HELRA – improvement plan for the functionality of Helsinki railway yard
• Finnish Transport Agency, 2014-2015
• The project was carried out in cooperation with Ramboll Finland Oy. The plan to improve the functionality of the railway yard was a continuation of the planning project carried out in 2012-2013 to reduce the railway yard’s sensitivity to disruptions and to improve its capacity.
• Proxion was responsible for project management as well signalling systems, railway electrification and high-voltage engineering.
