The MRT Purple Line (Thai: รถไฟฟ้ามหานคร สายสีม่วง) is a rapid transit line of the Bangkok MRT under construction for the Mass Rapid Transit Authority of Thailand (MRTA) in the Bangkok Metropolitan Region and Nonthaburi Province, Thailand. When it opens, it will be second line to be operated by MRT and the city's fifth rapid transit line. Following Sukhumvit Line, Silom Line, MRT Blue Line and Airport Rail Link. It is expected that the line will begin its operation on August 6, 2016.[1]

Description

The Purple Line is aimed to serve travel demand between the northwestern suburb of Bangkok in Nonthaburi Province and southern area of Thonburi in Rat Burana District. It also runs through downtown along Samsen Road, passing Rattanakosin old quarter and many historical places in Dusit and Phra Nakhon District like the national library, Thewet market, Bang Lamphu, the Democracy Monument, the Golden Mount, Phahurat, the Memorial Bridge and Wongwian Yai roundabout, and also intends to serve the new Thai parliament construction site at Kiak Kai intersection.

This Line is divided into two sections, Tao Pun - Khlong Bang Phai 23 km, which is under construction, and Tao Pun - Rat Burana, 19.8 km. The section from Tao Pun - Khlong Bang Phai was originally scheduled to be open in late 2014,[2] but is now due to open on 12 August 2016.

This will be the first Bangkok metro line into an adjacent province (Nonthaburi). The section links Tao Pun Station in Bang Sue, Bangkok, to Khlong Bang Phai Station in Bang Bua Thong, Nonthaburi Province. The MRT Blue Line extension between the existing Bang Sue terminus and Tao Pun is constructed as part of contract 1 to provide an interchange between both lines. The Purple Line will be operated Tao Pun - Khlong Bang Phai, comprising 16 stations along an elevated route. The first stage of construction commenced in early 2010.

The line is indicated by the colour purple on network maps.

Alignment

The Tao Pun - Khlong Bang Phai section starts from the Tao Pun elevated station at Tao Pun junction, where it transfers to the MRT Blue Line extension. It runs north on a viaduct along Krung Thep-Nonthaburi Road, providing transfer to the Red commuter railway at Bang Son railway station, and approaches Mueang Nonthaburi District of Nonthaburi Province. The line goes further north via Tiwanon Road, passes the Ministry of Public Health, then turns at the Khae Rai intersection to west Nonthaburi via Rattanathibet Road, passes the Nonthaburi Government Centre, crosses the Chao Phraya River on a viaduct parallel to the Phra Nangklao Bridge. Then it continues to a large residential area in Bang Yai District and turns to the north along the Kanchanaphisek Highway, passes Bang Yai market and terminates at Khlong Bang Phai in Bang Bua Thong District. The total length is 23 kilometres (14 mi).

Construction contracts

Construction is divided into three separate contracts. The first covers Bang Sue - Tao Pun - Phra Nangklao Bridge, with a length of 12 km, comprising nine stations. This contract also includes construction of a 1.2 km extension of the MRT Blue Line from Bang Sue to Tao Pun where the Blue Line and the Purple Line will interchange.

The second contract covers the Phra Nangklao Bridge (including a new bridge) - Bang Yai District - Khlong Bang Phai terminus, with a length of 11 km. and comprising seven stations. The third contract is for the construction of a train depot at the Bang Yai terminus and four park and ride buildings at Khlong Bang Phai, Bang Yai Intersection, Tha It, and the Nonthaburi Intersection station.

6 Trackwork

In September 2013, BEM (operator of the MRT Blue Line ) signed an 82.6-billion-baht contract with the MRTA for the procurement of rolling stock, installation of E&S systems, operation and maintenance of the Purple Line. The concession is for a 30-year period.[3]

The 6th contract, which was due to be awarded in mid-2011 for the laying of track was delayed for over one year due to internal disputes within the MRTA and uncertainty about the bidding process.[4] However, this contract was finalised in October 2012.

In October 2012, BEM, private operator of the MRT Blue line, was granted a 30-year concession to operate the Purple line and supply rolling stock & electrical systems.[5]

As of July 2014, civil works construction was 94% complete[6] which is 3% behind schedule.[7] As of October 2014, civil works were stated to be 99% complete.[8]

Rolling stock

In November 2013, BEM contracted Marubeni Corp, Toshiba Corp, and East Japan Railway Company to install E&S systems, supply 63 cars of rolling stock and provide maintenance for 10 years as part of a contract worth 12.6 billion baht.[9]

East Japan Railway train manufacturing subsidiary J-TREC will build the 21 trains (3 car sets) in Yokohama with delivery due in early 2016.[10]

Future extension

Phase 2, south:

The proposed extension from Tao Pun - Rat Burana will run southward through Bangkok's old quarter from Tao Pun junction on a viaduct. It then goes into an underground structure along Sam Sen Road, passing the new Thai parliament site, and transfers to the proposed Red inner-city shortcut commuter at Sanghi intersection. It passes the national library in Dusit District before it reaches Phra Nakhon District at Thewet Market. The line turns east at Bang Lamphu and goes along the city moat to the south, with transfers possible to the planned MRT Orange Line at Ratchadamnoen Road near the Democracy Monument. It also passes the Golden Mount before possible transfers to the southern extension of the Blue Line at Wang Burapha near Yaowarat Road in Chinatown and the Phahurat textile market.

The line crosses the Chao Phraya River near the Memorial Bridge towards the Wongwian Yai roundabout in Thonburi on the west bank, with possible transfers to the Dark Red Line commuter and to Wongwian Yai BTS Station. It continues south to Chom Thong, then on an elevated structure for 5.5 kilometres (3.4 mi) and terminates in Rat Burana District, a short distance to the nearby Phra Pradaeng suburban town in Samut Prakan Province. The total length will be about 19.8 km, and comprising eleven underground and five elevated stations.

North:

A 4.5 km extension from Bang Yai to Bang Bua Thong Intersection, which is not part of the original Purple Line plan, is under consideration due to a request from the Nonthaburi Governor.[11]
