Construction of the 145-kilometre Lop Buri-Pak Nam Pho double-track railway, which includes the country's longest elevated stretch at 19km, will be completed on schedule by the end of this year, the Department of Rail Transport (DRT) said on Thursday.
Five double-track railway routes, three of them to the South, are set to open this year with the aim of cutting journey times and increasing logistical efficiency, the government said on Monday.
