East Railway Ltd (Itärata Oy) has selected Finnmap Infra (part of the Solwers Group) and Sweco to draw up the general plan for the Porvoo-Koria section of the East Railway. The design agreement was signed on 16 June.

The East Railway is a planned rail connection from the Helsinki metropolitan area to Kouvola via Porvoo. The new line will provide faster rail connections for eastern Finland as a whole. It will strengthen links between eastern Finland and the Helsinki metropolitan area and improve connections to the airport.

Finnmap Infra is responsible for the general planning of the East Railway from Porvoo to Kouvola together with Sweco. Finnmap Infra's role includes, among other things, serving as project manager and lead designer responsible for rail design.

"The East Railway is a significant project for connections across eastern Finland. During the general planning phase, we see an opportunity to review different options and put forward even bold solutions together with our partners. The procurement process was carried out successfully, and in the workshops, we were able to demonstrate our expertise and ways of working in concrete terms. Our strong references and effective collaboration were clearly reflected in the evaluation," says Teemu Tuhkanen, Project Manager at Finnmap Infra.

A fast rail connection will open up new opportunities for business, make travel smoother for people and strengthen national resilience. In the east, the line will connect to the Savo and Karelia lines, and in the west, it will link to the planned Airport Rail Line between Pasila and Kerava.

The work starts with a development phase  

The East Railway is being planned as a double-track high-speed line. The total length of the line is approximately 118 kilometres. The line will be able to accommodate long-distance trains, commuter services and freight traffic.

The general planning phase, which began in summer 2026, will continue until 2028. The work will start with a development phase in which, among other things, the scope of the overall plan, the timetable and shared ways of working will be defined.

The general plan for the East Railway is divided into the Vantaa-Porvoo and Porvoo-Koria sections. Planning for the sections will be carried out in parallel. The aim is for services on the line to begin by 2040.
