context_page_description: The Metropolitan Rapid Transit or MRT is a mass rapid transit system serving the Bangkok Metropolitan Region in Thailand. The MRT system comprises two Medium-capacity rail system rail lines, with a further three lines currently under construction and due to open in 2021. The MRT Blue Line, officially the Chaloem Ratchamongkhon Line, between Hua Lamphong and Bang Sue was the first to open in 2004 as Bangkok's second metro system. The MRT Blue line is officially known in Thai as rotfaifa mahanakhon or "metropolitan electric train", but it is more commonly called rotfai taidin, literally, "underground train".
  The second MRT line MRT Purple Line, officially the Chalong Ratchadham Line, opened on 6 August 2016 and connected Tao Poon with Khlong Bang Phai in Nonthaburi in the northwest of Greater Bangkok. It was the first mass transit line to extend outside Bangkok province, Bangkok Metropolitan Administration.
  Both the Blue Line and Purple Line are operated by the Bangkok Expressway and Metro Public Company Limited under a concession granted by the Mass Rapid Transit Authority of Thailand which is the owner of the MRT lines.
context_section_description: The MRT was constructed under a concession framework. For the first MRT line, officially known as Chaloem Ratchamongkhon or informally as the "Blue Line", civil infrastructure was provided by the government sector, Mass Rapid Transit Authority of Thailand (MRTA), and handed over to their concessionaire under a 25-year concession agreement. Bangkok Expressway and Metro Public Company Limited (BEM) was the only private sector company that won a bid in MRTA's concession contract for the blue line. As MRTA's concessionaire, BEM provides M&E equipment, including electrical trains, signalling systems, SCADA, communication, PSD, etc. for the subway project and fully operates the system. To maintain the system, BEM has subcontracted in 10 years to Siemens which was the M&E system supplier since system opening and 7 years maintenance contract to two local maintenance services for north and south line.
  The construction of the first Bangkok Metro line, officially known as Chaloem Ratchamongkhon (Thai สายเฉลิมรัชมงคล) – "Celebration of Royal Auspice" – or informally as the "Blue Line", began on 19 November 1996. The project suffered multiple delays not only because of the 1997 economic crisis, but also due to challenging civil engineering works of constructing massive underground structures deep in the water-logged soil upon which the city is built.
  The Blue Line was opened for a limited public trial period of several weeks starting on 13 April 2004. On 3 July 2004 the line was officially opened at 19:19 local time by HM King Bhumibol and Queen Sirikit, who were accompanied by other members of the royal family. Within 30 minutes of its opening, sightseers filled the system to its maximum capacity, but after the initial rush ridership has settled down to around 180,000 riders daily — considerably lower than projections of over 400,000, despite fares being slashed in half from 12-38 baht to 10-15 baht per trip. From 2006 until 2008, fares ranged between 14-36 baht per trip. The fare was raised to 16-41 Baht on 1 January 2009. Daily ridership in 2014 was 253,000.
  In August 2016, the Purple Line opened for service. In August 2017, the MRT Blue Line was belatedly extended to Tao Poon station allowing interchange with the Purple Lines.
