Abstract：Research purposes:The proposed Laos-Thailand Railway Connecting Line is the key project of "the last kilometer" to connect the China-Laos Railway and China-Thailand Cooperation Railway and the key link to form the transportation capacity of the middle passage of the Trans-Asian Railway, and it is of great significance to promote the cooperation and development of regional countries and benefit the people in the surrounding areas. However, subject to the construction progress of Laos-Thailand Railway Connecting Line, the transportation capacity of the middle channel of the Trans-Asian Railway has not yet been formed, which has also been unfavorable to the transportation benefit of the China-Laos Railway. This paper makes a systematic study on the function positioning, passenger and freight volume, main railway technical standards, customs clearance mode, alignment, transshipment scheme, new Mekong River Railway Bridge scheme, the operation control model of cross-border trains, etc. Research conclusions:(1) It is recommended to adopt Chinese Standard gauge railway system, and the number of main lines shall be single track with reserving double tracks. (2) It is suggested that the "border control in separate locations" customs clearance mode and "transshipment in both sides" are adopted. (3) It is suggested that a new Mekong River Bridge is set at about 30 m downstream far from the existing bridge, and the piers of the new bridge are aligned with the existing piers, and the scales of new bridge are three tracks, which are single-track for meter gauge railway and double-tracks for standard gauge railway. (4) The cross-border operation of passenger trains automatically switches between CTCS-2 and CTCS-0 in the section, and the cross-border freight train maintains the combination mode of locomotive signal and train operation monitoring device as same as China-Laos Railway. (5) The research results have reference value for the construction of newly-built cross-border railway.
