Network identification

1. Background

2. Corridor studies

3. Objectives
1. Background

In the 1980s and early 1990s, economic growth in the Asia-Pacific region accelerates rapidly and international trade expands to unprecedented levels. Primarily designed to serve national needs, the transport systems of many countries of the region are often not prepared to address the sudden increase in cross-border traffic generated by the development of international trade.

Aware of the benefits of market integration and of the role of efficient transport in the process, the 48th session of the UNESCAP Commission (Shanghai, April 1992) launches the Asian Land Transport Infrastructure Development (ALTID) project. The objective is to identify and develop road and rail linkages best able to serve trade being exchanged across borders.

The extent of the territory to be covered, the differences in standards and the desire to ensure consistency with the work of other subregional organizations influence the choice of methodology. The idea of corridor studies receives the approval of member countries as the most pragmatic way of addressing all the relevant issue.

2. Corridor studies

Over the period 1994-2001, UNESCAP undertakes the following four corridor studies:

a northern corridor connecting the rail networks of China, Kazakhstan, Mongolia, the Russian Federation and the Korean Peninsula (1995, refined in 1999).
a subregional network covering the ASEAN and Indo-China subregions (1996). The countries involved are: Cambodia, China (Yunnan province), Indonesia, Lao PDR, Malaysia, Myanmar, Singapore, Thailand and Viet Nam.
a southern corridor (1999) connecting Thailand and the southern Chinese province of Yunnan with Turkey. The countries involved are: Bangladesh, China (Yunnan province), India, the Islamic Republic of Iran, Myanmar, Pakistan, Sri Lanka and Thailand.
a north-south corridor (2001) linking Northern Europe to the Persian Gulf through the Russian Federation, Central Asia and the Caucasus region. The countries involved are: Armenia, Azerbaijan, Finland, Georgia, the Islamic Republic of Iran, Kazakhstan, the Russian Federation, Turkmenistan and Uzbekistan.

3. Objectives

The objectives of the studies are to (i) identify the railway lines best able to serve international trade, (ii) assess their conformity with a set of technical requirements (e.g. loading gauges, axle-load, speed), and (iii) appraise the compatibility of operational practices between railway organizations on both sides of different national borders to evaluate the possibility and efficiency of cross-border movements (e.g. couplers, length of trains).

The studies also identify the structure of tariffs relating to international freight and the rules regulating the passage of goods across borders as important issues for the future efficiency of international rail freight corridors.

Finally, the studies assess the existence of break-of-gauge points along each corridor as well as the existence of so-called ‘missing links’ making end-to-end movements impossible on some of the routes.
