On a 2,832 km track, 2,432 are meter gauge, 400 are standard gauge (1,435 mm), of which 228 km are dual gauge.It extends from the Chinese border in the North to Ho Chi Minh City in the South. Two connections with Chinese Railway networkare operated, one-meter gauge at Lao Cai and one standard gauge at Dong Dang. The rolling stock includes 370 diesel locomotives,920 passenger cars and 4,500 freight wagons.

Hanoi–Vinh is the first 320 km section of the Hanoi–Ho Chi MinhCity (formerly Saigon) main line of Vietnam National Railways (VNR).Its modernisation includes the renewal of signalling and tele-communications systems to improve the safety of operations, to increase both the speed and transport capacity and provide a better reliability of the train circulation.

phase 1The first phase consists in the installation of: for Signalling•new electronic interlockings (SSI technology Alstom) in 3 main

stations: Van Dien, Bim Son and Than Hoa, •a new automatic level crossing equipment near Van Dien

station,•single track automatic block sections, on both sides of Than

Hoa station. for Telecommunications•an optical fibre cable along the 320 km of the line (24 fibres),•a multi-service transmission network based on SDH technol-

The works schedule foresees the commissioning of the new Sig-nalling and Telecommunications systems during the first quarter of 2005.

phase 2According to the preliminary studies, the second phase should include: for Signalling•new electronic interlockings in the remaining main stations

of the line,•single track automatic block sections for all the line, for Telecommunications•a track to train radio system,•a new optical cable for backup of the telecom network phase

1 (securisation).
