1. Introduction
The implementation of the “the Belt and the Road” initiative is a major strategic decision made by the Party Central Committee to actively respond to the profound changes in the global situation and to coordinate the two domestic and international situations. The interconnection and interoperability of the infrastructure, especially transportation infrastructure, of countries along the “the Belt and the Road” is an important prerequisite for the implementation of the “the Belt and the Road” strategy, and railways, especially highspeed railways, as one of the most important modes of transportation, play a role in the “the Belt and the Road” strategy. However, the current railway standards of the countries along “the Belt and the Road” are different, making it impossible for trains to run across borders, which greatly reduces the passenger 's cross-border travel experience and the efficiency of cargo transportation, which is not conducive to the economic recovery and development of countries along the Belt and Road. Therefore, this article analyzes the dynamic standards adopted by its locomotives for countries along “the Belt and the Road” including: Germany, Serbia, Indonesia, Iran, and Laos (corresponding to Western Europe, Central and Eastern Europe, Central Asia, Southeast Asia, and their inland regions). It also compares with the standards adopted in China to determine the differences between them. It provides a certain reference for China to establish a standard system of transnational interconnected high-speed train system components and achieve high-speed train transnational operations.
