The '''Yanchep line''', formerly the '''Joondalup line''', is a [[suburban railway]] line and service in [[Perth]], Western Australia, linking the city's central business district (CBD) with its northern suburbs. Operated by the [[Public Transport Authority (Western Australia)|Public Transport Authority]] as part of the [[Transperth]] system, the Yanchep line is {{convert|54.5|km}} long and has sixteen stations. It commences in a tunnel under the Perth CBD as a [[through service]] with the [[Mandurah line]]. North from there, the line enters the [[median strip]] of the [[Mitchell Freeway]], where nine of the line's stations are. The Yanchep line diverges from the freeway to serve the centre of [[Joondalup]] and permanently leaves the freeway north of [[Butler, Western Australia|Butler]] for the northernmost four stations to [[Yanchep]].

Planning for a [[rapid transit]] service to the northern suburbs began in 1987. After several [[Mode of transport|transport modes]] were considered, including [[bus rapid transit]], an electric railway was chosen. Known during planning and construction as the '''Northern Suburbs Railway''', the project was approved by state cabinet in late 1989 and construction began in November 1989. The line was built under several different contracts, with the total cost of the original project being [[A$]]277{{nbsp}}million. It used widely-spaced stations with bus interchanges and large [[park-and-ride]]s, distinguishing the line from Perth's three existing rail lines. The line opened on 20 December 1992 as the Joondalup line to limited service and with three stations: [[Leederville railway station|Leederville]], [[Edgewater railway station|Edgewater]] and [[Joondalup railway station|Joondalup]]. Four more stations opened in February 1993, and on 21 March 1993, [[Peak hour|peak]] service and [[feeder bus]] routes commenced. The final station, [[Currambine railway station|Currambine]], opened on 8 August 1993.

An extension north to [[Clarkson railway station, Perth|Clarkson station]] and rebuild of Currambine station opened on 4 October 2004, which coincided with the introduction of [[Transperth B-series train|B-series trains]]. On 29 January 2005, [[Greenwood railway station|Greenwood]] opened as an [[infill station]]. The Joondalup line originally through-ran with the [[Armadale line]] via [[Perth railway station|Perth station]], but in 2005, the line started terminating at Perth station, and on 15 October 2007 the line was rerouted through [[William Street tunnel|a new tunnel under the CBD]], with two new stations: [[Perth Underground railway station|Perth Underground]] and [[Elizabeth Quay railway station|Elizabeth Quay]]. The Mandurah line opened on 23 December 2007 to connect with the southern end of that tunnel. An extension north to [[Butler railway station|Butler station]] opened on 21 September 2014 and a three station extension north to [[Yanchep railway station|Yanchep station]] was opened on 14 July 2024, upon which the line became the Yanchep line.

B-series and [[Transperth C-series train|C-series]] trains are the main rolling stock used on the Yanchep line. Trains run at a fifteen minute headway, reducing to as low as a five minute headway in peak, with some services terminating at [[Whitfords railway station|Whitfords]] or Clarkson stations during peak. The travel time from Yanchep to Perth Underground is 49 minutes. The Yanchep line received 16,135,201 boardings in the 2023–24 [[financial year]], making it the second busiest line in the Transperth system, after the Mandurah line.

==History==

===Planning===
The 1955 ''[[Plan for the Metropolitan Region, Perth and Fremantle]]'', also known as the ''[[Gordon Stephenson|Stephenson]]–[[Alistair Hepburn|Hepburn]] Report'', proposed a {{convert|12|mi|km|adj=on}} railway line branching off the [[Eastern Railway (Western Australia)|Eastern Railway]] ([[Fremantle line]]) at [[Daglish, Western Australia|Daglish]], then heading west to Reabold Hill and then north to Whitfords Beach via [[City Beach, Western Australia|City Beach]], [[Scarborough, Western Australia|Scarborough]], and [[North Beach, Western Australia|North Beach]]. The branch was planned to have about eight or nine stations and projected to have about 20,000 daily passenger journeys. The report also proposed a highway to [[Yanchep]], now known as the [[Mitchell Freeway]].<ref>{{cite web |first1=Gordon |last1=Stephenson |author-link1=Gordon Stephenson |first2=Alistair |last2=Hepburn |author-link2=Alistair Hepburn |title=Plan for the Metropolitan Region, Perth and Fremantle |year=1955 |publisher=Government Printing Office |url=http://nla.gov.au/nla.obj-745050840 |id=nla.obj-745050840 |access-date=15 July 2024 |via=National Library of Australia |pages=120, 132}}</ref><ref>{{cite web |last1=Kennedy |first1=Peter |author1-link=Peter Kennedy (journalist) |title=Lib's public transport opportunity |url=https://www.businessnews.com.au/article/Libs-public-transport-opportunity |website=Business News |access-date=15 July 2024 |date=21 July 2011 |archive-date=8 September 2022 |archive-url=https://web.archive.org/web/20220908145114/https://www.businessnews.com.au/article/Libs-public-transport-opportunity |url-status=live }}</ref> When the [[Metropolitan Region Scheme]] was adopted in 1963 though, the land for the proposed highway was reserved but the not the land for the proposed railway.<ref>{{cite web |title=Metropolitan Region Scheme Map 13 |url=https://www.dplh.wa.gov.au/departmentofplanninglandsheritage/media/mapping/mrs/19631030_mrs_first_gazetted_edition_map_13.pdf |website=Department of Planning, Lands and Heritage |access-date=6 June 2021 |archive-url=https://web.archive.org/web/20210606092048/https://www.dplh.wa.gov.au/departmentofplanninglandsheritage/media/mapping/mrs/19631030_mrs_first_gazetted_edition_map_13.pdf |archive-date=6 June 2021 |date=1963 |url-status=dead}}</ref><ref>{{cite web |last1=Zimmerman |first1=Josh |title=Grandson of town planner Gordon Stephenson sets record straight |url=https://www.perthnow.com.au/community-news/melville-gazette/grandson-of-town-planner-gordon-stephenson-sets-record-straight-c-801312 |website=PerthNow |agency=Melville Gazette |access-date=9 May 2024 |date=22 February 2017 |archive-date=8 September 2022 |archive-url=https://web.archive.org/web/20220908145101/https://www.perthnow.com.au/community-news/melville-gazette/grandson-of-town-planner-gordon-stephenson-sets-record-straight-c-801312 |url-status=live }}</ref>

In 1979, the [[1979–1983 Fremantle railway line closure|Fremantle line was closed]] due to declining patronage, a lack of growth potential, and to save capital and operational costs.{{sfn|Committee for Perth|2011|p=5}} A group named the Friends of the Railways was formed to advocate against the closure. Among the group's other proposals was for the electrification of all three lines and the construction of a line to Joondalup. The ''Transport 2000: A Perth Study'' report, which was released in 1982, said that the electrification was not economically viable and that buses were sufficient to provide public transport in the northern suburbs.{{sfn|Committee for Perth|2011|p=6}} Following a [[Western Australian Labor Party|Labor Party]] victory in the [[1983 Western Australian state election|1983 state election]], the [[Fremantle line]] was reopened and planning for the electrification of the suburban rail system commenced.{{sfn|Committee for Perth|2011|p=7}}

Following the approval of electrification,{{sfn|Committee for Perth|2011|p=7}} the Northern Suburbs Rapid Transit Study was commissioned in 1987 by [[Metropolitan Transport Trust|Transperth]] and the Department of Transport at the request of the [[Government of Western Australia]]. The study, published in September 1988 and written by a team of consultants, considered possible [[modes of transport]] and the route to take.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=2}} Routes considered were along [[West Coast Highway, Perth|West Coast Highway]], [[Marmion Avenue]], the western side of the Mitchell Freeway, the [[median strip]] of the Mitchell Freeway, the eastern side of the Mitchell Freeway, [[Wanneroo Road]], and [[Alexander Drive]]. The median strip of the Mitchell Freeway was determined to have the lowest cost and least environmental impact out of each of the routes.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=4}} Transport modes considered by the study were buses on a separate roadway, buses on a [[guided bus]]way (like the [[O-Bahn Busway]] in [[Adelaide]]), [[light rail]], heavy rail, automated [[Rubber-tyred metro|rubber-tyred trains]], high-capacity [[monorail]], and an [[automated people mover]] system. A monorail or automated people mover were ruled out due to the cost and unproven nature of those technologies. Light rail was also ruled out due to having a lower operating speed than other modes and the desire to not introduce another mode to Perth's transport system.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=4}} A bus expressway, guided busway and electric railway along the Mitchell Freeway were all shortlisted for further consideration.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=4}}<ref>{{cite news |last1=Nicholson |first1=Brendan |title=New 'super buses' plan for city link |work=The West Australian |date=6 June 1988 |page=8}}</ref>

Public consultation found that 41.0 percent of people preferred an electric railway, 34.4 percent preferred a bus expressway, 19.3 percent preferred a guided busway, 3.2 percent did not want any rapid transit, and 2.2 percent preferred some other option. The people who preferred rail chose it because of its greater comfort, lower pollution and less crowding. The people who preferred the bus options chose them because there would be no transfer for trips into the Perth central business district (CBD) and the bus options would cost less than a railway.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=5}}  The study suggested that the bus options could be built in multiple stages and the rail option could first be built between Perth and [[Warwick, Western Australia|Warwick]] and later be extended to [[Joondalup]].{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=6}} The two bus options were projected to increase northern suburbs public transport patronage by fourteen percent and the rail option was projected to increase patronage by nine to twelve percent, less than the bus options due to the time taken to transfer from bus to train.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=7}} The net cost of the railway was estimated to be [[A$]]145{{nbsp}}million, compared to $87{{nbsp}}million for the guided busway and $79{{nbsp}}million for the bus expressway.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=9}} The study concluded that either of the bus options were preferred over the electrified railway, and that further studies should determine whether to build a bus expressway or a guided busway.{{sfn|Summary of the Northern Suburbs Rapid Transit Study|1988|p=11}}

In response to the Northern Suburbs Rapid Transit Study, the state [[Minister for Transport (Western Australia)|minister for transport]], [[Bob Pearce]], set up an expert panel consisting of [[Murdoch University]] Associate Professor [[Peter Newman (environmental scientist)|Peter Newman]], [[Tyne and Wear Metro|Tyne and Wear Transport]] Director General David F. Howard, and [[University of Pennsylvania]] Professor [[Vukan Vuchic]].{{sfn|Newman|Howard|Vuchic|1988|loc=Front cover, p. 1}} The expert panel concluded that an electrified railway would be the best option instead of a bus rapid transit system.{{sfn|Newman|Howard|Vuchic|1988|p=1}} They costed an electric railway at $124{{nbsp}}million and gave a lower operating cost for the railway compared to the bus options, making up the difference in cost within 12 to 15 years.{{sfn|Newman|Howard|Vuchic|1988|p=3}} The expert panel criticised the Northern Suburbs Rapid Transit Study for concentrating on commuters travelling to the CBD and said that the bus system the study recommended would not serve people doing short or local trips well.{{sfn|Newman|Howard|Vuchic|1988|p=11}} The panel said that other cities show that a rail trunk line with feeder buses would attract more passengers.{{sfn|Newman|Howard|Vuchic|1988|p=12}} State cabinet officially chose the railway option in December 1988.<ref>{{cite news |last1=Hooker |first1=Peter |title=Land deals may fund line |work=The West Australian |date=14 December 1988 |page=3}}</ref><ref>{{cite book |title=Annual Report 1988–1989 |author=Westrail |date=1989 |page=17}}</ref> The [[Western Australian Liberal Party|Liberal Party]] supported plans for a bus lane within the Mitchell Freeway, which prompted Pearce to claim that the Liberals did not want the railway.<ref>{{cite news |last1=Hooker |first1=Peter |title=Row over Coalition rail plans |work=The West Australian |date=21 January 1989 |page=6}}</ref><ref>{{cite news |title=Liberals 'against train' |work=The West Australian |date=23 January 1989 |page=24}}</ref>

State cabinet approved the Northern Suburbs Transit System Master Plan in the second half of 1989. The planned opening dates were the end of 1992 for Perth to Joondalup and the end of 1993 for Joondalup to Currambine.<ref name="Westrail Annual Report 1989–90">{{cite book |title=Annual Report 1989–1990 |author=Westrail |date=1990 |pages=29–30}}</ref> The master plan was released in November 1989. It laid out the route of the Northern Suburbs Railway and works proposed to occur. The railway was to be {{convert|29|km}} long and have seven new stations: [[Glendalough railway station|Glendalough]], [[Warwick railway station, Perth|Warwick]], [[Whitfords railway station|Whitfords]], [[Edgewater railway station|Edgewater]], [[Joondalup railway station|Joondalup]], and Burns (later renamed [[Currambine railway station|Currambine]]). It also gave the option of building stations at Oxford Street in [[Leederville, Western Australia|Leederville]], Wishhart Street between Stirling and Warwick, or [[Hepburn Avenue]] between Warwick and Whitfords.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=4}} [[Perth railway station|Perth station]], the centre of the rail network and southern terminus of the Northern Suburbs Railway, was planned to be expanded.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=7}} The railway's planned route was mostly along the median strip of the Mitchell Freeway, deviating in the Perth CBD to reach Perth station and in Joondalup to serve the future city centre of Joondalup. A section between Joondalup and Burns was to be west of the future freeway, which at the time only reached as far north as [[Ocean Reef Road]]. The section through Joondalup was to be in a trench below surface level to allow for roads to bridge across.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=2}} The railway was to be fully [[grade separated]] with no [[level crossing]]s, unlike Perth's existing rail network.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=11}}

The Northern Suburbs Railway's route was placed in the Mitchell Freeway's median strip to reduce costs as the freeway was already grade separated from other roads and had its own [[right of way]]. The disadvantage of freeway-running railways is that access to the stations is more difficult, with walking distance in earlier plans from a bus interchange to the platform being between {{convert|70|m}} and {{convert|180|m}}, and even longer for [[park and ride]] passengers. Earlier plans also had limited shelter and facilities at each station.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=19}} This was deemed bad for patronage, so the master plan instead located bus interchanges closer to the station platform. In the cases of Stirling, Warwick and Whitfords stations, the bus interchanges are on a bridge directly above the train platforms.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=21}} The feeder buses were planned to run between pairs of adjoining stations at a 10 to 15 minute headway in peak, covering the area between Wanneroo Road and the coastline. According to forecasts, two thirds of Northern Suburbs Railway passengers would use the feeder buses and 120 buses would be required. The opening of the railway would allow for express buses along the Mitchell Freeway to be phased out.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=7}}

Much of the Mitchell Freeway was designed with provisions for a public transport corridor in its median strip. However, a {{convert|5|km|adj=on|0}} section between [[Loftus Street]] in Leederville and Hutton Street in [[Osborne Park, Western Australia|Osborne Park]] was not. This section was built as a [[single carriageway]] with a dividing barrier. On that section, a [[Dual carriageway|second carriageway]], which now carries the freeway's northbound lanes, was planned to be constructed. Additional bridges would be built across Vincent Street, Powis Street, and [[Scarborough Beach Road]] for the new carriageway and the railway. Twelve other road bridges and nine pedestrian bridges needed minor modifications so that there was enough clearance for the overhead wires, and four bridges over the railway in Joondalup needed to be constructed.{{sfnm|Northern Suburbs Transit System Master Plan|1989b|1p=18|Northern Suburbs Transit System Progress Summary|1991|2p=6}}<ref name="Main Roads book">{{cite book |last1=Edmonds |first1=Leigh |author1-link=Leigh Edmonds |title=The Vital Link: A History of Main Roads Western Australia 1926–1996 |date=1997 |publisher=University of Western Australia Press |isbn=978-1-876268-06-0 |page=395}}</ref> New stowage tracks at [[Claisebrook railway depot|Claisebrook depot]] would be required, and trains would also be stored at Whitfords station temporarily and at Currambine station.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=11}}

The total cost of the Northern Suburbs Railway was estimated to be $222.8{{nbsp}}million (equivalent to ${{Inflation|AU|222.8|1989}}{{nbsp}}million in {{Inflation-year|AU}}), of which $133.17{{nbsp}}million was for the railway's construction and $89.63{{nbsp}}million was for the acquisition of 22 two-car [[electric multiple unit]] trains. An additional $27{{nbsp}}million for the works to widen the Mitchell Freeway between Leederville and Osborne Park was funded separately{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=25, 28}} and managed by the [[Main Roads Western Australia|Main Roads Department]].<ref name="Main Roads book"/> The rest of the construction works were managed by [[Westrail]]. The $222.2{{nbsp}}million was higher than the $150{{nbsp}}million estimated in 1988 due to an underestimation in the cost of some parts of the project, increased facilities at stations, more bridges, the extension to Currambine which was not accounted for, additional railcars due to higher forecasted demand, and inflation.{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=1, 31}} The railway was planned to open between Perth and Joondalup by the end of 1992 and from Joondalup to Currambine by the end of 1993,{{sfn|Northern Suburbs Transit System Master Plan|1989b|p=26}} although meeting the 1992 deadline was regarded as unrealistic as it meant that detailed design and construction had to occur in three years.<ref name="The West Australian 19 December 1992a"/>

===Construction===
In November 1989, the [[Fremantle line]] was realigned north between Perth station and the Mitchell Freeway to make way for the [[Roe Street, Perth|Roe Street]] tunnel.

==Service==
[[Transperth]] train services are operated by the [[Public Transport Authority (Western Australia)|Public Transport Authority]]'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=10 November 2024}}</ref> Yanchep line train headways reach as low as five minutes during peak, increasing to fifteen minutes outside peak and on weekends, and half-an-hour to an hour at night. During peak, some services terminate or commence at Whitfords or Clarkson stations. The travel time from Yanchep station to Perth Underground station is 49 minutes. On weeknights, the last train arrives at Yanchep station at 1:06{{nbsp}}am and the first train departs at 4:38{{nbsp}}am. On Saturday and Sunday nights, the last train arrives at Yanchep station at 3:04{{nbsp}}am and the first train departs at 5:05{{nbsp}}am on Saturdays and 6:28{{nbsp}}am on Sundays.<ref name="Timetable">{{cite web |title=Yanchep Line Train Timetable |url=https://www.transperth.wa.gov.au/timetablepdfs/Yanchep%20Line%2020241209.pdf |website=Transperth |access-date=23 January 2025 |date=9 December 2024}}</ref>

During events at [[Perth Stadium]], additional services operate along the Yanchep line direct to [[Perth Stadium railway station|Perth Stadium station]], bypassing Perth station.<ref>{{cite web |title=new Perth Stadium Transport Project Definition Plan |url=https://www.pta.wa.gov.au/Portals/15/AA_DOCUMENTS/Projects/Perth%20Stadium%20Transport%20PDP.pdf |website=Public Transport Authority |access-date=16 November 2024 |page=12 |date=December 2012}}</ref><ref>{{cite web |title=Optus Stadium |url=https://www.transperth.wa.gov.au/Journey-Planner/Optus-Stadium |website=Transperth |access-date=16 November 2024}}</ref>

Before January 2016, express services operated on the Yanchep line during peak periods to manage overcrowding. The introduction of more B-series sets allowed for most trains during peak to be six cars long, which increased capacity and allowed for all services to stop at all stations from 31 January 2016 onwards.<ref>{{cite web |last1=Acott |first1=Kent |title=Bus, rail and ferry services to change |url=https://thewest.com.au/news/australia/bus-rail-and-ferry-services-to-change-ng-ya-135013 |website=The West Australian |access-date=12 November 2024 |date=9 January 2016}}</ref><ref>{{cite web |title=Bus, Train and Ferry – Major Timetable Changes |url=http://www.transperth.wa.gov.au/Service-Updates/Service-Update-Details/bus-train-and-ferry-major-timetable-changes-17580 |website=Transperth |archive-url=https://web.archive.org/web/20160203164354/http://www.transperth.wa.gov.au/Service-Updates/Service-Update-Details/bus-train-and-ferry-major-timetable-changes-17580 |archive-date=3 February 2016 |date=31 January 2016 |url-status=dead}}</ref> Before then, some peak trains from Perth to Butler or Clarkson skipped Leederville and Glendalough, and trains from Perth to Whitfords skipped Greenwood.<ref>{{cite web |title=Joondalup Line Train Timetable |url=http://www.transperth.wa.gov.au/timetablepdfs/Joondalup%20Line%2020140921.pdf |website=Transperth |archive-url=https://web.archive.org/web/20150112102021/http://www.transperth.wa.gov.au/timetablepdfs/Joondalup%20Line%2020140921.pdf |archive-date=12 January 2015 |date=21 September 2014 |url-status=dead}}</ref> Before June 2009, services terminating at Whitfords operated off-peak as well, making for 7½-minute headways between Perth and Whitfords during the day.<ref>{{cite web |title=Joondalup Line Timetable |url=http://www.transperth.wa.gov.au/timetablePDFs/Joondalup%20Line%2020080817.pdf |website=Transperth |archive-url=https://web.archive.org/web/20080727133823/http://www.transperth.wa.gov.au/timetablePDFs/Joondalup%20Line%2020080817.pdf |archive-date=27 July 2008 |date=17 August 2008 |url-status=dead}}</ref><ref>{{cite web |title=Joondalup Line Timetable |url=http://www.transperth.wa.gov.au/timetablePDFs/Joondalup%20Line%2020090301.pdf |website=Transperth |archive-url=https://web.archive.org/web/20090612015859/http://www.transperth.wa.gov.au/timetablePDFs/Joondalup%20Line%2020090301.pdf |archive-date=12 June 2009 |date=1 March 2009 |url-status=dead}}</ref> The Perth to Whitfords service is sometimes known as the Whitfords shuttle.<ref name="Media Statement 30 December 2004"/> These services were withdrawn to save money.<ref name="Media Statement 4 June 2009">{{cite press release |first1=Simon |last1=O'Brien |title=Timetables change as train capacity boosted |url=https://www.wa.gov.au/government/media-statements/Barnett%20Liberal%20National%20Government/Timetables-change-as-train-capacity-boosted-20090604 |publisher=Government of Western Australia |access-date=12 November 2024 |date=4 June 2009}}</ref><ref>{{cite news |last1=Kerr |first1=Peter |title=Shuttle train service cuts will save $2m |work=The West Australian |date=5 June 2009 |page=6}}</ref><ref>{{cite web |last1=Thomson |first1=Chris |title=Cockburn to Whitfords trains slashed |url=http://www.watoday.com.au/wa-news/cockburn-to-whitfords-trains-slashed-20090630-d3o5.html |website=WAtoday |archive-url=https://web.archive.org/web/20090704040739/http://www.watoday.com.au/wa-news/cockburn-to-whitfords-trains-slashed-20090630-d3o5.html |archive-date=4 July 2009 |date=1 July 2009 |url-status=dead}}</ref>
