'''Trams in Helsinki''' form part of the [[Public transport in Helsinki|public transport system]] organised by [[Helsinki Regional Transport Authority]] and operated by [[Metropolitan Area Transport Ltd]] ({{langx|fi|Pääkaupunkiseudun Kaupunkiliikenne Oy}}, {{langx|sv|Huvudstadsregionens Stadstrafik Ab}}) in Finland's capital city of [[Helsinki]]. The trams are the main means of transport in the city center, and 56.8 million trips were made on the system in 2019.<ref name="vuosikertomus-2023"/><ref name="ridership">{{Cite web|date=2022-12-31|title=Matkustajamäärät 1.1.-31.12.2022|trans-title=Ridership numbers|url=https://hslfi.azureedge.net/globalassets/hsl/tutkimukset/matkustajamaarat/hsl_matkustajamaarat-0101_31122022.pdf|access-date=2023-09-07|website=Metropolitan Area Transport Ltd|language=fi}}</ref> In addition to the older tram network, there is a [[Helsinki light rail line 15|single light rail line]] that was opened in October 2023. Although technically compatible with the tram network, the light rail line is separate from the city center tram network.<ref>{{Cite web |date=2023-05-24 |title=Päätös antaa pikaratikalle numero 15 kuohuttaa helsinkiläisiä – Näin HSL vastaa |url=https://www.hs.fi/kaupunki/helsinki/art-2000009604502.html |access-date=2023-10-22 |website=Helsingin Sanomat |language=fi}}</ref>

In addition, the [[SpåraKoff]] pub tram has operated during the summer months since 1995.<ref>{{Cite web |last=Moilanen |first=Kaisu |date=2015-05-07 |title=Keskiolutta raitiovaunussa! – Spårakoff oli ilmestyessään suuri nähtävyys, jossa on kosittu ja vietetty häitä |url=https://www.hs.fi/ihmiset/art-2000002821952.html |access-date=2024-01-01 |website=Helsingin Sanomat |language=fi}}</ref>

=== Network ===
The tram network is built almost exclusively on the streets of Helsinki, making it a traditional [[streetcar|tram]] system rather than [[light rail]]. The [[track gauge]] is [[metre gauge|one metre]]. The network consists almost entirely of [[Double-track railway|double track rail]]. In some parts the tracks are separated from other road traffic; elsewhere they share road space with cars and buses.

The trams are powered with electricity conveyed by 600 V DC [[Overhead line|overhead wires]], although the voltage is planned to be raised to 750 V in 2025.<ref name="banaani"/> Trams have their own [[traffic light]]s, distinguished from normal lights in that they are based on symbols of single colour: an upward-pointing arrow signifies "go", a horizontal line "prepare to go/stop" and the letter S "stop". The traffic lights are synchronised to allow tram and bus traffic to flow relatively smoothly. This system is called HeLMi (Helsinki Public Transport Signal Priority and Passenger Information).<ref name="misc1">[[#notemisc1|Helsinki Urban Traffic Control Centre]]</ref> [[Helsinki light rail line 15|Line 15]] uses a different system based on inductive loops and requests from the trams themselves. Line 15's traffic lights also have a fourth aspect: a circle above the letter S, which signifies that the traffic light has acknowledged receipt of a request for the tram. On the inner-city network, a small flashing LED is provided with the S aspect.

{{As of|2022|11}}, HKL has 122 tram units in scheduled passenger service. Additionally, there are trams in reserve and in charter use. The MLNRV I and II series (rebuilt [[Valmet Nr I]] and [[Valmet Nr II]] units) and [[Škoda Artic]] series comprise the city center fleet, and the light rail line 15 uses bidirectional [[Škoda Artic X54]] units.

In 2006–2011, all Valmet Nr II (at that point known as NRV II) vehicles underwent a major modification process in which a {{convert|6.5|m|ftin|abbr=on}} [[Low-floor tram|low-floor]] midsection was added to the tram. The type designation was changed to MLNRV II to reflect the modifications made, and the longer trams were re-introduced in traffic gradually as the modification works were completed. During the process, HKL also rebuilt ten of the older Nr I trams (at that point known as NRV II) in the same way, which brought the total number of MLNRV trams to 52 upon completion in mid-2014.

The fully low-floor [[Stadler Variobahn|Variotram]] units, acquired in 1998–2003 from [[Adtranz]] (later [[Bombardier Transportation|Bombardier]]) and built by [[Transtech Oy]] in [[Otanmäki]], proved to be unreliable, causing a shortage of operable trams. Starting in 2004, HKL purchased ten [[Duewag]] series second-hand trams from [[Trams in Mannheim/Ludwigshafen|Mannheim]] in Germany to cover for the shortage.<ref>{{Cite web |last=Alku |first=Antero |date=2007-07-13 |title=Düwag GT6 |url=https://www.kaupunkiliikenne.net/GT6.html |access-date=2024-01-01 |website=www.kaupunkiliikenne.net}}</ref> Eventually arrangements were made with Bombardier to keep a sufficient number of the units in operation. All of the Duewag units were either withdrawn or relegated to charter service by the end of 2014. All Variotrams were taken out of use in 2018 because of the problems.<ref>{{Cite web |last=Nieminen |first=Tommi |date=2000-09-02 |title=Ratikkaliikenne jatkuu Arabianrantaan asti |url=https://www.hs.fi/kaupunki/art-2000003908255.html |access-date=2024-01-01 |website=Helsingin Sanomat |language=fi}}</ref><ref>{{Cite web |last=Salomaa |first=Marja |date=2017-08-22 |title=HKL hankkiutuu eroon vanhoista matalalattiaraitiovaunuista – Bombardier maksaa korvauksia 33 miljoonaa euroa |url=https://www.hs.fi/kaupunki/art-2000005336282.html |access-date=2023-07-30 |website=Helsingin Sanomat |language=fi}}</ref>

Beginning in 2013, HKL acquired 72 new Artic trams. They have a double-articulated, eight-axle design, are {{convert|27.3|m|ftin|abbr=on}} long and have 74 fixed seats, 14 foldable seats and space for 75 standing passengers.<ref>{{Cite web |date=2010-12-02 |title=Transtech toimittaa uudet raitiovaunut |url=https://yle.fi/a/3-5680813 |access-date=2024-01-01 |website=Yle Uutiset |language=fi}}</ref> The design has a 100% low floor and conventional, turning bogies designed to run without problems on Helsinki's challenging old-fashioned track network.<ref>{{Cite web |last=Malmberg |first=Lari |date=2016-01-02 |title=Tervetuloa hiljainen raitiovaunukyyti – ensimmäinen Artic-raitiovaunu saapuu Helsinkiin kahden viikon päästä |url=https://www.hs.fi/kaupunki/art-2000002877794.html |access-date=2023-07-30 |website=Helsingin Sanomat |language=fi}}</ref> Two prototype units were delivered in 2013, and each entered passenger service approximately two months after delivery.

[[Helsinki City Transport]], the predecessor of Metropolitan Area Transport, has ordered 29 Artic X54 units for [[Jokeri light rail|line 15]], of which 15 are in service,{{as of?|date=January 2024}} and 23 for the [[Crown Bridges]] [[light rail]] lines.

Metropolitan Area Transport announced a [[Invitation to tender|tender]] in October 2023 to acquire new rolling stock to replace the aging MLNRV fleet and to support new services such as the [[Vantaa light rail]]. The procurement includes 30 unidirectional and 33 bi-directional units and is estimated to be valued at €1.6 billion.<ref>{{Cite web |last=Preston |first=Robert |date=2023-10-13 |title=Helsinki launches €1.6bn tender for 63 new LRVs |url=https://www.railjournal.com/passenger/light-rail/helsinki-launches-e1-6bn-tender-for-63-new-lrvs/ |website=International Railway Journal}}</ref>

{{As of|2023|4}}, there are several tram depots and workshops in Helsinki. The city center tram services currently use [[Töölö]] and [[Koskela]] and a maintenance facility in [[Vallila]]. A new depot for 100 trams and 200 buses is being built in [[Ruskeasuo]] and the new depot, combined with a rebuild of the aging Koskela depot, is planned to eventually fully replace the Töölö and Vallila facilities.<ref>{{Cite web |last=Takala |first=Sami |date=2022-07-05 |title=Helsingin Ruskeasuolle rakennetaan jättimäinen raitiovaunujen ja bussien varikko |url=https://www.hs.fi/kaupunki/art-2000008925340.html |access-date=2023-08-01 |website=Helsingin Sanomat |language=fi}}</ref><ref>{{Cite web |last=Pannanen |first=Veera |date=2021-11-16 |title=Koskelan raitiovaunuvarikon kaarihalliin suunnitellaan "kiertotalouskorttelia" |url=https://www.hs.fi/kaupunki/art-2000008406433.html |access-date=2023-08-01 |website=Helsingin Sanomat |language=fi}}</ref><ref>{{Cite web |last=Oksanen |first=Kimmo |date=2023-04-27 |title=Keskellä Helsinkiä sijaitsee työpaikka, jota joskus luullaan museoksi – Silti loppu jo häämöttää |url=https://www.hs.fi/kaupunki/helsinki/art-2000009539681.html |access-date=2023-08-01 |website=Helsingin Sanomat |language=fi}}</ref><ref>{{Cite web |last=Kirsi |first=Katri |date=2020-12-03 |title=HKL laittaa 360 miljoonaa raitiovaunuvarikoihin – Ylen saama selvitys paljastaa: Varikkotilat silti liian pienet? |url=https://yle.fi/a/3-11677868 |access-date=2023-08-01 |website=Yle Uutiset |language=fi}}</ref>
