Question: The Munabao Barmer Passenger is a passenger train of which State owned national transporter, responsible for rail transport in India?
Context: Thar Link Express (Hindi: थार लिंक एक्सप्रेस ) is the Indian portion of the international passenger train Thar Express operated weekly by Indian Railway using its own coaches and locomotives, between Jodhpur and Munabao.  Passengers from Munabao then clear customs and are transported to across the border to Zero Point station where the Thar Express takes passengers to Karachi, Pakistan. Transport in Greater Nagoya (Chūkyō) is similar to that of the Tokyo and Osaka, but is more automobile oriented, as the urban density is less than Japan's two primary metropolises, and major automobile manufacturers like Toyota are based here.  Still, compared to most cities of its size worldwide it has a considerable rail transport network with 3 million passenger trips daily, with a similar density and extent of passenger rail to London or New York City, (as of May 2014, the article Nagoya rail list lists 59 lines, 16 operators, 1,547.8 km of operational track and 654 stations [although stations recounted for each operator], note this data does not include any high speed rail) complemented with highways and surface streets for private motor transport.  It includes public and private rail and highway networks; airports for international, domestic, and general aviation; buses; motorcycle delivery services, walking, bicycling, and commercial shipping.  The nexus of the public transport system is Nagoya Station.  Every region of Greater Nagoya, also known as the Chūkyō Metropolitan Area (中京圏 ) , has rail or road transport services, and the area as a whole is served by sea and air links. The Ocean, previously known as the Ocean Limited, is a passenger train operated by Via Rail in Canada between Montreal, Quebec and Halifax, Nova Scotia.  It is currently the oldest continuously operated named passenger train in North America.  The "Ocean"'s schedule takes approximately 23 hours, running overnight in both directions.  Together with "The Canadian" and Via's corridor trains, the "Ocean" provides a transcontinental service. In rail transport, head-end power (HEP) or electric train supply (ETS) is the electrical power distribution system on a passenger train.  The power source, usually a locomotive at the front or 'head' of a train (or a generator car), provides the electricity used for heating, lighting, electrical and other 'hotel' needs.  The maritime equivalent is hotel electric power.  A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger car between London and Brighton heralded the beginning of using electricity to light trains in the world. Passenger Train Journal "(PTJ)" is an American magazine about passenger rail transport and rail transit past and present, oriented for railfans and published currently by White River Productions.  Founded in 1968, it was published continuously until 1996, and monthly from 1979 onward, but then ceased publication.  After a 10-year absence, it was restarted in 2006 with a different publishing company, as a quarterly magazine.  "PTJ" deals exclusively with passenger rail, not freight.  Although focused on North America, each issue includes at least a small amount of content on overseas—usually European—passenger rail.  The magazine is headquartered in Lee, Illinois. Rail transport in Central America consists of several isolated railroad lines with freight or passenger service.  The most famous one is the Panama Canal Railway, the oldest transcontinental railroad in the world, connecting Panama City with Colón since 1855.  Other railroads in Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama were built by private and public investors mainly to facilitate the transport of local agricultural produce (bananas, coconuts, coffee) to export markets and harbors.  Their market share and profitability went into decline in the second half of the twentieth century and most lines have been decommissioned by the end of the 1990s.  As of 2010, railroads operate locally in El Salvador, Honduras, Costa Rica and Panama only; all rail transport has been suspended in Belize, Guatemala and Nicaragua.  None of the operating railways crosses national borders. Ukrainian Railways (Ukrainian: Укрзалізниця, "Ukrzaliznytsia" ) is a state owned enterprise of rail transport in Ukraine, a monopoly that controls vast majority of the railroad transportation in the country with a combined total tracks length of over 23,000 km, making it the 14th largest in the world.  Ukrainian Railways is also the world's 6th largest rail passenger transporter and world's 7th largest freight transporter. Indian Railways (reporting mark IR) is a State owned national transporter, responsible for rail transport in India.  It is owned and operated by the Government of India through the Ministry of Railways.  It is the third largest railway network in the world comprising 119630 km of total track and 92081 km of running track over a route of 66687 km with 7,216 stations at the end of 2015-16.  In 2015-16, IR carried 8.107 billion passengers annually or more than 22 million passengers a day and 1.101 billion tons of freight annually.  As of the end of 2015-16, of the total 68525 km route length, 28327 km or 45% were electrified and 28371 km or 37% were double or multiple line routes.  The railway network is predominantly a broad gauge network.  Small stretches of the network use metre and narrow gauges.  All the electrified lines use 25 kV AC electric traction. The Munabao Barmer Passenger is a passenger train of the Indian Railways, which runs between Barmer railway station of Barmer of Rajasthan and Munabao railway station of Munabao, of Indian state Rajasthan. Rail transport in Puerto Rico currently consists of a 10.7 mi passenger metro system in the island's metropolitan area of San Juan.  Its history can be traced back to the mid-19th century with the construction of a limited passenger line in Mayagüez.  Between the late 19th and early 20th centuries, Puerto Rico's rail transport system expanded significantly, becoming one of the largest rail systems in the Caribbean at the time thanks to an economic boom in agriculture industries, especially the sugar cane industry.  The rail system was expanded to include passenger travel with a direct line from the island's northern capital of San Juan to the western and southern cities and towns, greatly improving travel and communication within the island.  However, the entire system was soon overshadowed by the arrival of the automobile, and by the 1950s was completely abandoned.  Small remnants of this system still exist in some parts of Puerto Rico, some conserved for tourism purposes.
