a record 22,365 million tonne-km in the first 6 months of 2010. Also, Ferrosur, the railroad serving Mexico City and cities/ports southeast of Mexico City, hauled their own record 3,565 million tonne-kilometers. There were two southern concessions, merged in 2000 to form Ferrosur. Ferrosur operates the line between Mexico City and the Gulf of Mexico port of Veracruz. In 2005, Ferrosur was bought by Ferromex's parent company. KCSM challenged the acquisition and the merger failed to receive regulatory approval. However, in March 2011, a tribunal ruled in Grupo México's favor, and the merger was permitted. The three major Mexican railroads jointly own Ferrocarril y Terminal del Valle de México (Ferrovalle) which operates railroads and terminals in and around Mexico City. Revival of passenger service In 2006, the Secretariat of Communications and Transport of Mexico proposed a high-speed rail link that will transport its passengers from Mexico City to Guadalajara, Jalisco, with stops in the cities of Querétaro, Guanajuato, Leon and Irapuato; and a connected line running from the port city of Manzanillo to Aguascalientes. The train would travel at 300 km/h, and would allow passengers to travel from Mexico City to Guadalajara in just 2 hours at an affordable price (the same trip by road would last 7 hours). The network would also be connected to Monterrey, Chilpancingo, Cuernavaca, Toluca, Puebla, Tijuana, Hermosillo, Cordoba, Veracruz, Oaxaca, Colima, Zacatecas, Torreon, Chihuahua, Puebla, San Luis Potosi, Mexicali, Saltillo, and Acapulco by 2015. The whole project was projected to cost 240 billion pesos, or about 25 billion dollars. Mexican billionaire Carlos Slim expressed an interest in investing in high-speed rail. President Enrique Peña Nieto proposed a return to services of intercity trains, the proposed projects are Mexico City-Toluca (construction began July 7, 2014), the Peninsular train (Yucatán-Mayan Riviera), Mexico-Querétaro high speed train starts construction October 2014 and will operate speeds up to 300 km/h (with expansion to Guadalajara) and Puebla-Tlaxcala-Mexico City. On November 3, 2014, China Railways Construction Corporation associated with Prodemex, Teya and GHP has won the contract to build the high Speed train Mexico City-Querétaro. The estimated cost will be close to 4 billion dollars, to be finished by the end of 2017 and will be fully operational by spring 2018. However, Mexico canceled the contract four days later because of doubts over the bidding process. In 2015, Mexico opened a new tender, which was revoked again. Hence, Mexico could indemnify
