Helsinki City Transport
A Helsinki municipal transport organization that operates selected public transport services, including parts of the Helsinki Metro, under contract to the Helsinki Regional Transport Authority.
Last updated August 22, 2026
Overview
Helsinki City Transport, commonly known as HKL, is a public transport organization owned by the City of Helsinki. Its Finnish name is Helsingin kaupungin liikennelaitos and its Swedish name is Helsingfors stads trafikverk; HST is also used as an abbreviation for the organization. The entity has historically been associated with the planning, organization, and operation of public transport within Helsinki, particularly the city’s tram and metro systems. Before the creation of the Helsinki Regional Transport Authority, known as HSL, in January 2010, HKL was responsible for planning and organizing all public transport in Helsinki. This role changed when HSL was established as the regional authority responsible for transport planning, commissioning, and related arrangements across the Helsinki metropolitan area. HKL subsequently became one of the contractors working for HSL rather than the sole organization responsible for the city’s public transport system. HKL’s operating profile has included urban rail and other municipal transport functions. Its best-known service areas are the Helsinki Metro and Helsinki tram network, while bus operations were historically part of the wider municipal transport structure. The city’s bus operations were combined with those of another city-owned company, Suomen Turistiauto, to create Helsingin Bussiliikenne. That bus company was later acquired by Koiviston Auto, separating the former municipal bus activity from HKL’s remaining core operations. A further organizational change took place in February 2022, when most of HKL’s operations, apart from certain parts of the Metro operation, were corporatized and transferred to Metropolitan Area Transport Ltd. This restructuring reduced the scope of HKL as a directly operating municipal organization. HKL nevertheless remains associated with Helsinki’s public transport system and continues to conduct selected operations connected with the Helsinki Metro as a contractor to HSL. HKL is therefore best understood not as a nationwide commercial transport brand, but as a Helsinki-owned public-sector transport operator and service organization whose responsibilities have changed over time. Its history reflects the division of responsibilities between the City of Helsinki, HSL as the regional transport authority, municipal operating entities, and private or corporatized service providers.
History
Helsinki City Transport, abbreviated HKL, is the municipal transport organization historically associated with Helsinki’s public transport system. Its official Finnish name is Helsingin kaupungin liikennelaitos, while the Swedish equivalent is Helsingfors stads trafikverk. HST is another abbreviation used for the organization. For much of its history, HKL combined transport planning, organization, and operations within Helsinki. Its responsibilities covered the city’s municipal public transport framework and included major urban rail modes such as the tramway and metro. This gave HKL a central role in the development and day-to-day functioning of Helsinki’s local transit system. The creation of the Helsinki Regional Transport Authority, HSL, in January 2010 changed the institutional structure of public transport in the Helsinki area. Before HSL existed, HKL was responsible for planning and organizing all public transport in Helsinki. After the regional authority was established, HSL took on the transport authority role, while HKL became one of the operators or contractors carrying out services commissioned within the regional system. HKL’s bus activities were also separated from its other functions. The municipal bus operations were merged with those of Suomen Turistiauto, another city-owned company, creating Helsingin Bussiliikenne. This entity later passed into private ownership through its acquisition by Koiviston Auto. The change marked a further reduction in the direct role of the City of Helsinki in bus operations. The most significant recent restructuring occurred in February 2022. Most of HKL’s operations were corporatized and moved to Metropolitan Area Transport Ltd. Certain parts of the Metro operation were excluded from that transfer. As a result, HKL no longer represented the whole of Helsinki’s former municipal transport operation, although it retained a continuing connection with selected Helsinki Metro activities. In its current historical context, HKL is consequently a narrower organization than the citywide transport authority and operator it once represented. Its continuing role is linked to contracted public transport work, especially aspects of Metro operations, within a system organized regionally by HSL. The organization’s development illustrates the progressive separation of transport authority functions, operating functions, municipal ownership, and corporatized service delivery in the Helsinki metropolitan area.

Products and positioning
A city-owned public transport operator and infrastructure-related service organization supporting Helsinki’s urban mobility system, with a historical role in citywide transport planning and a continuing contracted role in selected metro operations.
Helsinki Metro operationsUrban rail transport
HKL is associated with operating selected parts of the Helsinki Metro as a contractor to the Helsinki Regional Transport Authority. The Metro is one of the organization’s principal continuing areas of activity, although not every Metro-related function was retained by HKL after the 2022 corporatization.
Helsinki tram servicesTram transport
Tram transport is one of the major urban mobility functions historically associated with Helsinki City Transport. HKL’s former municipal transport portfolio included the city tram system, although most of the organization’s operations were transferred to Metropolitan Area Transport Ltd in 2022.
Municipal bus operationsBus transport
Bus operations were historically part of Helsinki’s municipal transport structure. HKL’s bus activities were combined with those of Suomen Turistiauto to form Helsingin Bussiliikenne, which was later acquired by Koiviston Auto. These operations are therefore no longer an HKL-controlled municipal offering.
