The '''MRT Purple line''' ({{langx|th|รถไฟฟ้ามหานคร สายสีม่วง}}) or '''The M.R.T. Chalong Ratchadham Line''' ({{langx|th|รถไฟฟ้ามหานคร สายฉลองรัชธรรม}}) is Bangkok's [[Mass Rapid Transit Master Plan in Bangkok Metropolitan Region|fifth rapid transit line]], following the [[Sukhumvit Line]], [[Silom Line]], [[Blue Line (Bangkok)|Blue Line]], and [[Airport Rail Link (Bangkok)|Airport Rail Link]]. The line is {{convert|23|km|abbr=on}} long,<ref name="KE-20160510" /> serving the north-western area of Bangkok running from [[Tao Poon MRT station|Tao Poon]] to [[Khlong Bang Phai MRT station|Khlong Bang Phai]] in [[Nonthaburi Province]].

The Purple line starts from [[Khlong Bang Phai MRT station|Khlong Bang Phai]] station in [[Bang Bua Thong District]]. The line travels south along Kanchanaphisek Road before turning eastward near [[Central WestGate]], onto [[Rattanathibet Road]]. It continues along Rattanathibet Road, passing through a large residential area in [[Bang Yai District]] and crosses the [[Chao Phraya River]] on a bridge parallel to the [[Phra Nang Klao Bridge]] and runs towards [[Nonthaburi Civic Center MRT station|Nonthaburi Civic Center]] station. The line then turns southward onto Tiwanon Road, passing the [[Ministry of Public Health MRT Station|Ministry of Public Health]] and turns southeast onto Krung Thep-Nonthaburi Road, entering [[Yaek Tiwanon MRT Station|Yaek Tiwanon]] station. The line then enters Bangkok city limits at Bang Sue district and passes [[Bang Son MRT station|Bang Son]] station before terminating at the upper platforms of [[Tao Poon MRT station|Tao Poon]] station, with a total length of {{convert|23|km|4=2}}, serving 16 stations.

== History == Officially named the Chalong Ratchadham Line ({{langx|th|สายฉลองรัชธรรม}}) – "To Celebrate the Great King's Reign with Righteousness"<ref name="metro.bemplc.co.th">{{Cite web|title=BEM บริษัททางด่วนและรถไฟฟ้ากรุงเทพจำกัด (มหาชน)|url=https://metro.bemplc.co.th/MRT-System-Line?pid=2|access-date=2020-06-22|website=metro.bemplc.co.th|language=th}}</ref> – but informally known as the "Purple Line", the rapid transit line provides a north–western corridor in [[Mass Rapid Transit Master Plan in Bangkok Metropolitan Region|Bangkok's Mass Rapid Transit Master Plan]]. The line also incorporated an extension of the Blue Line from nearby [[Bang Sue MRT station|Bang Sue]] station to [[Tao Poon Station]].

In the 1990s, the plan for the Purple Line was to run from Bang Phut to Bang Sue for {{Convert|12|km}}, with an extension to [[Thewet Naruemit Bridge|Thewet]] for {{Convert|6.7|km|sp=us}}.<ref name="Urban Railway Projects In Bangkok">{{Cite web |title=Urban Railway Projects In Bangkok - Measures for Securing Financial Resources |url=https://www.jica.go.jp/Resource/jica-ri/IFIC_and_JBICI-Studies/jica-ri/english/publication/archives/jbic/report/oecf/pdf/25_e.pdf}}</ref>

This line was created from the adjustment of the 1994 mass transit rail system master plan, which connected the original extension of the Blue Line from Tao Poon to Bang Yai, while the original Purple Line would have run from the National Library to Tao Poon and the original [[Orange Line (Bangkok)|Orange Line]] from Samsen (National Library) to Rat Burana, becoming a new line designated as the Purple Line, included in the master plan of the Office of Transport and Traffic Policy and Planning (OTP) for the first time in 2004. Five years later, the line's construction began.

== Northern section == Construction was divided into six contracts, three of them for civil works. The contracts were signed from late 2009 to early 2010 and completion was originally scheduled for the end of 2014.<ref name="thairath.co.th-2009">{{Cite web|date=2009-08-26|title=ลงนามสัญญาที่1 รถไฟสีม่วง ช.การช่างได้เฮ|url=https://www.thairath.co.th/content/28906|access-date=2020-06-21|website=thairath.co.th|language=th}}</ref><ref name="thairath.co.th-2010">{{Cite web|date=2010-01-20|title=รฟม.ลงนามสัญญา 2 สายสีม่วง มูลค่า 1.31 หมื่นล้านแล้ว|url=https://www.thairath.co.th/content/60041|access-date=2020-06-21|website=thairath.co.th|language=th}}</ref><ref name="mgronline.com-2009">{{Cite web|url=https://mgronline.com/business/detail/9520000070869|access-date=2020-06-25|website=mgronline.com|title=รฟม.ตัดเค้กสัญญา 3 รถไฟฟ้าสายสีม่วง "อิตาเลียนไทย" ได้ทานแห้ว|date=23 June 2009}}</ref><ref>{{Cite web|title=รถไฟฟ้าสายสีม่วงบางซื่อ-บางใหญ่ฉลุยเซ็นรับเหมาครบ3สัญญา ลงมือก่อสร้างก.พ.นี้ 3 ปีครึ่งเสร็จ !!|url=http://www.thailog.org/index.php?option=com_k2&view=item&id=1917:3-3&Itemid=524|access-date=2020-06-25|website=www.thailog.org|language=en-gb}}</ref> The third contract included construction of four [[park and ride]] buildings at the [[Khlong Bang Phai MRT Station|Khlong Bang Phai]], [[Sam Yaek Bang Yai MRT station|Sam Yaek Bang Yai]], [[Bang Rak Noi Tha It MRT Station|Bang Rak Noi Tha It]], and [[Yaek Nonthaburi 1 MRT Station|Yaek Nonthaburi 1]] stations.

The line opened on 6 August 2016, when King [[Bhumibol Adulyadej]] appointed Princess [[Sirindhorn|Maha Chakri Sirindhorn]] to represent him in presiding over the opening ceremony and officially pressing the button to open the electric train system.<ref name="Bangkok Post" /><ref>[http://www.prachachat.net/news_detail.php?newsid=1462201042 พิธีเปิดการเดินรถ และกดปุ่มเปิดระบบรถไฟฟ้าอย่างเป็นทางการ]</ref> However, the MRT Blue Line extension to Tao poon was delayed, so when it opened the Purple Line could not interchange with the Blue Line as planned. This resulted in low line usage. Even with a reduced fare, the line only attracted about 22,000 passengers daily compared to a goal of 100,000. A shuttle bus service was in operation between [[Tao Poon MRT station]] and [[Bang Sue MRT station]] to connect with the Blue Line.<ref>{{Cite web|title=Fare cut boosts Purple Line riders, but still below target |url=http://property.bangkokpost.com/news/1081544/fare-cut-boosts-purple-line-riders-but-still-below-target|access-date=11 September 2016|website=Bangkok Post}}</ref> When the Blue Line extension finally opened a year later, on 11 August 2017,<ref>{{Cite news|title=Purple Line to connect with MRT on Aug 11|url=https://www.bangkokpost.com/thailand/general/1285890/purple-line-to-connect-with-mrt-on-aug-11|access-date=2020-04-24|newspaper=Bangkok Post|date=12 July 2017 }}</ref><ref>{{Cite web|title=เปิดวิ่งเชื่อมต่อสถานีเตาปูน-บางซื่อ 12.00 วันนี้|url=https://www.bangkokbiznews.com/news/detail/768436|access-date=2020-06-25|website=bangkokbiznews.com/|date=11 August 2017 |language=en}}</ref> ridership significantly increased.

=== Park & Ride === There are currently four Park & Ride facilities along the MRT Purple Line, at [[Khlong Bang Phai MRT station|Khlong Bang Phai]], [[Sam Yaek Bang Yai MRT station|Sam Yaek Bang Yai]], [[Bang Rak Noi Tha It MRT station|Bang Rak Noi Tha It]], and [[Yaek Nonthaburi 1 MRT station|Yaek Nonthaburi 1]] stations. Two additional facilities are under construction at [[Bang Pakok MRT station|Bang Pakok]] and [[Rat Burana MRT station|Rat Burana]] stations as part of the Purple Line Southern Section project.

=== Station === The MRT Purple Line comprises 33 stations, with 16 currently in operation since 2016—all of which are elevated. The remaining 17 stations are under construction and expected to be completed by 2029, consisting of 10 underground and 7 elevated stations.

Station structures on the MRT Purple Line North Section range from 300 to 400 meters in length and approximately 18 meters in width. In the Southern Section, underground stations typically measure 250 meters in length and 20 meters in width, while elevated stations are 153 meters long and 25 meters wide. All stations are designed to accommodate a maximum of six cars per train. Elevated stations are equipped with half-height platform screen doors, while underground stations will be fitted with full-height platform screen doors. In addition, the entrances to the stations are designed to be about one meter above ground level, taking into account the highest recorded flood levels in Bangkok to prepare for potential future flooding events.

=== Rolling stock === In November 2013, BEM contracted with [[Marubeni]] Corp, [[Toshiba]] Corp, and [[East Japan Railway Company]] to install E&S systems, supply 21 three-car trains (total of 63 cars) rolling stock, and provide maintenance for 10 years as part of a contract worth 12.6 billion baht.<ref>'Japanese firms win Purple Line deal'.

=== Signaling system === [[Cityflo 650 CBTC|Bombardier Cityflo 650 signaling system]] has been implemented for the MRT Purple Line project. This [[Communications-based train control|communication-based train control]] (CBTC) system supports [[automatic train operation]] (ATO), allowing for efficient and safe control of train movements. It enables real-time train monitoring, optimizing operations and minimizing delays while prioritizing passenger safety. Additionally, the system ensures a minimum headway of just ninety seconds.<ref>{{Cite web |title=Bombardier Contributes to Increased Connectivity Across Bangkok |url=https://www.railway-technology.com/contractors/data//pressreleases/pressbombardier-contributes-increased-connectivity-bangkok/ |access-date=2025-04-29 |website=Railway Technology |language=en-US}}</ref>

== Operation ==

=== Service hour === The line operates with varying schedules across stations. The first train departs from [[Khlong Bang Phai MRT station|Khlong Bang Phai station]] at 5:30 AM and from [[Tao Poon MRT station|Tao Poon station]] at 6:00 AM. The frequency of train services depends on the time of day and passenger volume. The service hours are determined by the departure time of the last train heading to [[Khlong Bang Phai MRT station|Khlong Bang Phai station]]. For example, when the last train departs from [[Tao Poon MRT station|Tao Poon station]] at 11:24 PM, that marks the closing time for all stations, with the final closure occurring at [[Talad Bang Yai MRT station|Talad Bang Yai Station]].

=== Fares === MRT Purple Line fare is calculated based on the travel distance between the origin and destination stations. Previously, fares ranged from 14 to 42 baht, with a maximum of 70 baht when transferring to the MRT Blue Line.

==== Implementation of the 20-Baht Fare Cap (2023–2025) ==== Following the introduction of the policy in October 2023, fares were reduced to a range of 14 to 20 baht, with a new maximum of 51 baht when transferring to the Blue Line. Discounted fares were available for children under 14 and senior citizens, starting at 7 baht and capped at 36 baht with a Blue Line transfer. Student fares started at 13 baht and rise to 48 baht when including a transfer to the Blue Line.

The policy was discontinued on 30 November 2025 and was replaced by a 40-baht daily fare cap for credit or debit card users; this policy also applies to the SRT Red Lines.<ref name=":1" /><ref name=":2" />

==== EMV Payment and Transfer Privileges ==== [[EMV]] Card users will receive a 15 baht discount when transferring from the Purple Line to the [[Pink Line (Bangkok)|Pink Line]], and a 14 baht discount when transferring in the opposite direction. Senior citizens are eligible for an 8 baht discount when transferring from the Purple Line to the [[Pink Line (Bangkok)|Pink Line]], and a 7 baht discount when transferring from the [[Pink Line (Bangkok)|Pink Line]] to the Purple Line. Students will receive a 15 baht discount when transferring from the Purple Line to the [[Pink Line (Bangkok)|Pink Line]], and a 13 baht discount when transferring from the [[Pink Line (Bangkok)|Pink Line]] to the Purple Line.<ref>{{Cite web |title=อัตราค่าโดยสาร |url=https://www.mrta.co.th/th/fares |access-date=2025-04-29 |website=www.mrta.co.th |language=th}}</ref>

Following the Cabinet's approval on 25 November 2025, a new 'Daily Fare Cap' measure was introduced to reduce the cost of living, effective from 1 December 2025 to 30 November 2026. This policy applies to travel on the MRT Purple Line and SRT Red Lines. General passengers using EMV Contactless cards are subject to a maximum fare of 40 baht per day. Students are eligible for a 10% discount on fares with a daily cap of 30 baht, provided the same card is used for all trips. Meanwhile, state welfare cardholders, persons with disabilities, senior citizens, and children continue to receive their existing discounts or fare exemptions; specifically, senior citizens remain entitled to a 50% discount.<ref>{{Cite news |last=Reporters |first=Online |date=2025-10-30 |title=B40 daily flat fare approved for Red and Purple lines |url=https://www.bangkokpost.com/thailand/general/3128786/b40-daily-flat-fare-approved-for-red-and-purple-lines |access-date=2025-12-13 |work=Bangkok Post |language=en}}</ref>

== Incidents == === 2025 Myanmar earthquake === On 28 March, a [[2025 Myanmar earthquake|7.7-magnitude earthquake in Myanmar]] struck Bangkok, leading to the temporary suspension of all train services to ensure readiness for resumption and to prepare for potential aftershocks.

=== 2025 Bangkok road collapse === {{Main|2025 Bangkok road collapse}}

On 24 September 2025, a section of [[Samsen Road]] collapsed, creating a large [[sinkhole]] in front of [[Vajira Hospital]]. The hole was estimated to be about 30 metres wide and nearly 50 metres deep, swallowing several vehicles and damaging water pipes, power lines, and other infrastructure. Although no injuries were reported, parts of the Sam Sen police station and nearby buildings were evacuated, and the hospital suspended some services for two days as a precaution.

Officials linked the collapse to soil erosion associated with the construction of the MRT Purple Line South section and a possible leakage from water pipes beneath the road. Initial repair work involved pouring large amounts of concrete into the cavity, but engineers were forced to stop when the material began seeping into a nearby tunnel through a breach in its wall. By the following day, the ground continued to shift, complicating stabilization efforts. Authorities responded by closing off the area, installing monitoring equipment, and preparing plans for a permanent retaining wall.

The [[Bangkok Metropolitan Administration]] stated that full repairs would require thousands of tonnes of concrete and additional engineering measures. Inspections of surrounding structures are ongoing, and traffic on Samsen Road is expected to resume by 9 October 2025.<ref>{{Cite web |last=español |first=Leer en |date=2025-09-24 |title=A Bangkok road collapse creates a sinkhole disrupting traffic and prompting evacuations |url=https://apnews.com/article/thailand-bangkok-sinkhole-road-collapse-f9278e530ca3b93e152cfab6c961dbd7 |access-date=2025-10-02 |website=AP News |language=en}}</ref><ref>{{Cite news |date=2025-09-24 |title=Thailand works to tackle massive sinkhole in capital |url=https://www.reuters.com/world/asia-pacific/thailand-works-tackle-massive-sinkhole-capital-2025-09-24/ |access-date=2025-10-02 |work=Reuters |language=en}}</ref><ref>{{Cite web |date=2025-09-26 |title=Bangkok Sinkhole Repair Halted After 1,500 Tonnes of Concrete Leak into Tunnel |url=https://www.nationthailand.com/news/general/40055956 |access-date=2025-10-02 |website=nationthailand |language=en-US}}</ref><ref>{{Cite news |date=2025-09-24 |title=Large Hole Swallows Road in Bangkok After a Subway Tunnel Collapses |url=https://www.nytimes.com/2025/09/24/world/asia/bangkok-sinkhole-thailand.html |archive-url=https://web.archive.org/web/20250924160659/https://www.nytimes.com/2025/09/24/world/asia/bangkok-sinkhole-thailand.html |archive-date=2025-09-24 |access-date=2025-10-02 |language=en}}</ref>
