context_page_description: The railway network of Thailand is managed and operated by the State Railway of Thailand and has a route length of 4,346 km. 151 km or 3.47% of all the routes are electrified.
context_section_description: Bangkok is currently served by three rapid transit systems: the BTS Skytrain, the MRT and the Airport Rail Link. Although proposals for the development of rapid transit in Bangkok had been made since 1975, leading to plans for the failed Lavalin Skytrain, it was only in 1999 that the BTS finally began operation.
  In addition to rapid transit and heavy rail lines, there have been proposals for several monorail systems, the most notable being a line linking Chulalongkorn University with Siam Square, to be funded by the BMA. In 2010 Grand Canal Land Company proposed a 600–800-metre line linking its properties on Rama IX Road with the Phra Ram 9 MRT Station, but failed to secure approval.
  The Mass Rapid Transit Master Plan in Bangkok Metropolitan Region has plans for the following rapid transit lines:
  Development is divided into three stages, in addition to those lines already open or under construction:
