The Finnish Transport Infrastructure Agency is responsible for the management, development and maintenance of the Finnish rail network. The Agency’s activities are aimed at maintaining the operating condition of the rail network in order to ensure its safe and efficient use.
As at the end of 2014, Finland has 5,944 kilometres of railways in use, of which 3,256 kilometres are electrified lines. This includes 5,342 kilometres of single-track railways. Nearly EUR 200 million a year is spent on track maintenance.
The rail width of the Finnish rail network is 1524 mm, which differs from the rail width of 1435 mm in use in most parts of Europe. The electric railway voltage is 25 kV and frequency 50 Hz. For most of the rail network, the maximum authorised axle weight is 22.5 tonnes. In certain parts of the rail network, an axle weight of 25 tonnes is also permitted. The speed limit for passenger trains is 220 km/h, and 120 km/h for freight trains.
The Finnish rail network is connected to Sweden via Tornio, and to Russia via Vainikkala, Imatrankoski, Niirala and Vartius.
