sentences:  In 2012, MMC announced plans to construct a railway from Ukhaa Khudag to the Gashuun Sukhait border crossing, to be completed in 2015.While that particular plan apparently did not come to fruition, the railway along the same or similar route was said to be under construction as of 2014, with the estimated completion date in late 2016.A special vote of the Mongolian Parliament made it possible to construct this railway on the 1435 mm standard gauge (for a seamless connection with China's railway network), rather than on the 1520 mm Russian gauge used elsewhere in Mongolia.
