Jokeri Line: first light rail system in Helsinki

Jokeri Line is a 25‑kilometre orbital light rail connection linking Helsinki and Espoo in Finland’s capital region. Replacing the region’s busiest bus route, the line provides a high‑capacity, reliable public transport backbone. With the growth expectations, local authorities are seeking to meet carbon‑neutrality targets by encouraging travel by public transport.

Sustainable connectivity

Jokeri Line 15 supports mobility in Finland’s capital region by strengthening east–west public transport connections between Helsinki and Espoo. Replacing the region’s busiest bus route, the high‑capacity light rail system provides a reliable alternative to road‑based travel. It forms a long‑term public transport backbone that supports regional growth while helping reduce congestion and emissions across a rapidly urbanising corridor.

“Light Rail Line 15 is the first light rail connection in the Helsinki region. Rail connections are instrumental in building a carbon neutral public transport system for the metropolitan area. Moreover, they are accelerating urban development by providing increased line of sight related to land use for investors and developers.”

Capacity for growth

This page has a tag of:

Replacing the Helsinki region’s busiest bus route, Jokeri Line Line 15 delivers a step change in capacity along the corridor. By 2030, the line is expected to serve around 90,000 passengers on a typical workday, more than doubling previous passenger volumes. This high‑capacity light rail system provides the long‑term transport backbone needed to support continued population growth, new jobs, and urban development across Helsinki and Espoo.
