station in 1993 and another track of the Kerava Urban Line reached Tikkurila station in 1996. 2000s A new urban section running parallel to the Coastal Line, the Leppävaara Urban Line, was instated in 2001 with two new tracks for commuter services only. The Lahti Line, opened in 2006, splits from the Main Line after Kerava station. The hourly commuter service running on it is known as the train. 2010s The Ring Rail Line opened in 2015, connecting the Vantaankoski Line to the Main Line via Helsinki Airport and four other newly opened stations. Unlike other Helsinki commuter rail lines, part of the Ring Rail Line runs in a tunnel with the Airport station and Aviapolis station being located underground. It is possible to construct a branch to Klaukkala in the future. In the late 2010s, operations of the commuter trains were opened for competition for the first time ever. HSL prequalified seven companies for tendering in 2018 and two years later, chose to award the contract to VR until 2031, citing higher than expected cost savings in VR's proposal. Future extensions Espoo City Railway The Leppävaara Urban Line – two tracks reserved exclusively for commuter trains, running parallel to the Coastal Line – is about to be extended by 14 km to Espoo station, thus becoming the Espoo City Railway. Work on the extension began in late 2021 and is expected to be completed in 2028. The project is overseen by the Finnish Transport Infrastructure Agency and will allow for higher frequencies for westbound services such as the and trains in the near future. Other proposals Projects such as the City Rail Loop, the Vantaankoski Line branch to Klaukkala and the Kerava Urban Line branch to Nikkilä have been put on hold indefinitely. Services All services begin and terminate at Helsinki Central, thus, only the final destination of each service is mentioned next to the service identifier. All services also call at Pasila station in both directions. Coastal Line Stopping train to Leppävaara The A train is the most frequent westbound service on the system, also being the shortest service on the entire Helsinki commuter rail. It has been operated in its current form since 2002, as made possible by the construction of the Leppävaara Urban Line which runs parallel to the Coastal Line. The A calls at all stations on its route. For a short period of time
