Provides the latest statistics on the U.S. railways and diesel locomotives; describes the recent developments of GM and GE locomotive manufacturing companies in the United States and their latest series of products - the main technical parameters and structural features of the 60 series and Dash8 series diesel locomotives The focus of the development of the diesel locomotives in the United States in the 1990s is outlined. These include the development of AC locomotives, microcomputer control technology, exhaust emission control, alternative fuels, wheel / rail lubrication, improved design of diesel engines, radial bogies, In view of the status quo of railway transportation in our country, some suggestions and suggestions should be drawn from the experiences of the United States, appropriate research on the natural gas combustion of diesel locomotives, popularization and application of wheel / rail lubrication technology and how to develop the high-speed railway transportation in China.
