The '''Armadale line''' is a partially-closed [[suburban rail]]way service in [[Perth]], Western Australia, operated by the [[Public Transport Authority (Western Australia)|Public Transport Authority]] as part of the [[Transperth]] system. The Armadale line is {{convert|30.4|km}} long, and starts at [[Perth railway station|Perth station]], heading south-east of there to serve Perth's south-eastern suburbs, terminating at [[Armadale railway station, Perth|Armadale station]]. Since June 2025, the line has been closed from [[Beckenham railway station|Beckenham Station]] to Armadale for the Rail Revitalisation Program and Byford extension with services operating between Perth and Cannington, as Beckanham is only being serviced by Thornlie-Cockburn Line services.

The Armadale line originated from suburban services along the [[South Western Railway, Western Australia|South Western Railway]] in the 1890s. Suburban services were extended over the first half of the 20th century to eventually reach Armadale station. Diesel services commenced in 1954, which allowed for the opening of more stations closer together. Electrification occurred in the early 1990s, and in 2005, the [[Thornlie–Cockburn line|Thornlie line]] opened as a branch of the Armadale line south of [[Beckenham railway station|Beckenham]]. From 20 November 2023, the Armadale line between Victoria Park and Armadale stations shut down for 18 months. The line reopened between Victoria Park and Beckenham in June 2025. The remainder of the line is expected to re-open in late-2025.<ref>{{Cite news |date=2025-03-30 |title=Further disruption to Perth commuters as south-east train line delayed |url=https://www.abc.net.au/news/2025-03-30/metronet-armadale-train-line-reopening-delayed-/105114332 |access-date=2025-06-08 |work=ABC News |language=en-AU}}</ref> 

Before the shutdown, Armadale line services ran at four trains per hour during the day, rising to seven trains per hour during peak. Armadale line trains typically stopped at all stations between Armadale and [[Cannington railway station|Cannington]] and skipped most stations between Cannington and Perth, with the exception of [[Oats Street railway station|Oats Street]], [[Claisebrook railway station|Claisebrook]], and [[McIver railway station|McIver]] stations. Thornlie line trains instead stopped at all stations between Cannington and Perth. [[Transperth A-series train]]s are mainly used. The Armadale and Thornlie lines received 3,878,183 boardings in the 2023–24 financial year. Since June 2025, trains have operated at four trains per hour between Perth and Cannington.

==History==
The [[South Western Railway, Western Australia|South Western Railway]] between [[Perth]] and [[Pinjarra, Western Australia]], opened on 22 May 1893. An extension south to [[Bunbury, Western Australia|Bunbury]] opened on 22 August 1893. Services were operated by the [[Western Australian Government Railways]] (WAGR).{{sfn|Arnold|2006|p=4}} Initially, the railway had a limited passenger service, run by [[mixed train]]s. Suburban service were not provided, with trains going all the way to Bunbury.{{sfn|Higham|2007|p=21}}

By 1900, there were three daily suburban return services from Perth to [[Cannington railway station|Cannington]]. [[Kelmscott railway station|Kelmscott]] and [[Armadale railway station, Perth|Armadale]] were considered to be country towns, and were served by the daily train to and from Bunbury.{{sfn|Higham|2007|p=75}} By 1906, there were suburban services along the South Western Railway as far as [[Maddington railway station|Maddington]].{{sfn|Higham|2007|p=73}} [[Seaforth railway station|Seaforth]] station opened on 4 May 1948 as the line's first new station in several decades.<ref name="PTA history"/><ref>{{cite news |url=http://nla.gov.au/nla.news-article46907049 |title=Advertising |newspaper=The West Australian |date=1 May 1948 |access-date=20 July 2023 |page=24 |via=National Library of Australia}}</ref>

Diesel [[railcar]]s were introduced in 1954, starting with the [[WAGR ADG class]]. Those trains could manage more closely spaced stations than steam-hauled ones, so three new stations opened on 28 November 1954: [[Oats Street railway station|Oats Street]], Higham (now [[Beckenham railway station|Beckenham]]), and Stokely (closed 1989).<ref name="28 November 1954">{{cite news |url=http://nla.gov.au/nla.news-article59698258 |title=New Timetables for Suburbans |newspaper=The Sunday Times |date=21 November 1954 |access-date=5 July 2023 |page=6 |via=National Library of Australia |archive-date=19 July 2021 |archive-url=https://web.archive.org/web/20210719093223/https://trove.nla.gov.au/newspaper/article/59698258 |url-status=live }}</ref><ref>{{cite news |url=http://nla.gov.au/nla.news-article52966996 |title=Advertising |newspaper=The West Australian |date=27 November 1954 |access-date=20 July 2023 |page=22 |via=National Library of Australia}}</ref>{{sfn|Higham|2007|p=87}} By 1954, suburban services ran as far as Armadale station. Because the Armadale line was not as busy as the [[Fremantle line|Fremantle]] and [[Midland line, Perth|Midland]] lines, the Armadale line had a train every 40 minutes, as opposed to the other lines, which had trains every 20 minutes.{{sfn|Higham|2007|p=75}}

Suburban development in Perth's south-east corridor rapidly increased following the adoption of the [[Metropolitan Region Scheme]] in 1961 and the ''[[Corridor Plan for Perth]]'' in 1970.{{sfn|Higham|2007|p=75}} Kingsley (now [[Sherwood railway station, Perth|Sherwood]]) and [[Challis railway station|Challis]] stations both opened in 1973 between Kelmscott and Armadale stations.<ref name="PTA history"/><ref>{{cite web |title=Historical timeline since settlement |url=https://www.armadale.wa.gov.au/historical-timeline-settlement |website=City of Armadale |access-date=20 July 2023}}</ref> Only after the [[1979–1983 Fremantle railway line closure|1979 closure of the Fremantle line]] was there enough rolling stock for Armadale line services to reach the frequency of Midland line services.{{sfn|Higham|2007|p=75}} On 2 July 1980, a redeveloped Kelmscott station opened, with a bus interchange on the station platform. That was an early example of a bus-train interchange that would become commonplace on the later [[Yanchep line|Yanchep]] and [[Mandurah line|Mandurah]] lines.<ref name="PTA history"/><ref>{{Citation |title=MetroBus Annual Report 1997–1998 |author=MetroBus |date=1998 |pages=41–68}}</ref>

[[Transperth]] was adopted as the trading name of the [[Metropolitan Transport Trust]] in 1986. The Armadale line was electrified in the early 1990s, with the electric [[Transperth A-series train]]s entering service in September 1991.<ref name="PTA history" /> Stokely station was closed on 16 April 1989 because it was the Armadale line's least-used station and it close to [[Maddington railway station|Maddington station]]. Closing Lathlain station was proposed as well, but it remained open during electrification.<ref name="Stokely station closure">{{cite web |title=Legislative Assembly |url=https://www.parliament.wa.gov.au/Hansard/hansard1870to1995.nsf/83cc4ce93b5d4e0b48257b33001cfef6/0CEC1D9CFF3EE48848257A310025A56C/$File/19890411_Assembly.pdf |website=Parliament of Western Australia |access-date=18 November 2023 |page=113 |date=11 April 1989}}</ref> In 2003, the [[Public Transport Authority (Western Australia)|Public Transport Authority]] was formed to take over from WAGR and the Department of Transport.<ref name="PTA history"/> Between 21 March 1993 and 8 August 2005, trains on the Armadale line continued through Perth to the [[Yanchep line|Joondalup line]], now known as the Yanchep line.

==Service==
Trains operate between Perth and Cannington stopping at all stations. Services operate at a 7.5 minute frequency during the day, and every 15 minutes at night. Train services on the rest of the line will resume in 2025 when the Armadale Line Shutdown is completed.

[[Transperth]] train services are operated by the PTA's Transperth Train Operations division.<ref>{{cite web |title=Transperth |url=https://www.pta.wa.gov.au/our-services/transperth |website=Public Transport Authority |access-date=18 July 2023}}</ref> Before the start of the shutdown, Armadale line trains operated at four trains per hour during the day, rising to seven trains per hour during [[Peak hour|peak]]. At night, frequencies reduced to every half an hour, and every hour late at night. Armadale line trains typically stopped at all stations between Armadale and Cannington and skipped most stations between Cannington and Perth, with the exception of Oats Street, Claisebrook, and McIver stations. Thornlie line trains instead stopped at all stations between Cannington and Perth. Armadale line trains only stopped at all stations on Sundays when Thornlie line trains were less frequent, and late at night when Thornlie line trains do not operate. Operating hours were from roughly 5:00 am to 1:00 am, extending to 3:00 am on Saturday and Sunday mornings.<ref name="Timetable">{{cite web |title=Armadale/Thornlie Line Train Timetable |url=https://www.transperth.wa.gov.au/timetablepdfs/Armadale%20Thornlie%20Line%2020221010.pdf |website=Transperth |access-date=20 July 2023}}</ref>

[[File:Transperth A-Series 39 @ Armadale.jpg|thumb|right|A [[Transperth A-series train]] at [[Armadale railway station, Perth|Armadale station]]|alt=Electric multiple unit train at a brick station platform with a crowd of people and shelter overhead]]

The Armadale line is served primarily by [[Transperth A-series train]]s, with [[Transperth B-series train]]s occasionally used as well. By 2031, it is planned that all A-series trains will be retired, leaving the Armadale line to be served primarily by B-series trains. The A-series trains were built between 1991 and 1999 and consist of two cars which are usually joined together to form four car trains. Each car has two doors on each side. The B-series trains were built between 2004 and 2019, consist of three cars each and have two doors on the side of each car. These trains are all primarily stored at [[Claisebrook railway depot|Claisebrook depot]].

===Patronage===
The Armadale and Thornlie–Cockburn lines combined are the third most patronised Transperth lines, after the [[Mandurah line]] and the [[Yanchep line]]. The two lines combined received 3,878,183 boardings in the year to June 2024.<ref name="Patronage" />
