Higher Speed Rail
Higher-speed rail (HrSR), also known as high-performance rail, higher-performance rail, semi-high-speed rail or almost-high-speed rail, is the jargon used to describe inter-city passenger rail services that have top speeds of more than conventional rail but are not high enough to be called high-speed rail services. The term is also used by planners to identify the incremental rail improvements to increase train speeds and reduce travel time as alternatives to larger efforts to create or expand the high-speed rail networks. Some countries use the term medium-speed rail, or semi-high speed rail instead. Though the definition of higher-speed rail varies from country to country, most countries refer to rail services operating at speeds up to . The concept is usually viewed as stemming from efforts to upgrade a legacy railway line to high speed railway standards (speeds in excess of ), but usually falling short on the intended speeds. The faster speeds are achieved through various ...

China Railway CR200J
The CR200J Fuxing ( zh, s=复兴号, p=Fùxīng Hào "Rejuvenation") is a Chinese higher-speed trainset consisting of a power car paired with unpowered passenger cars operated by China Railway. It is the slowest member of the Fuxing series. The train was jointly designed and produced by six companies under CRRC. These units are nicknamed ''Green EMUs'' or ''Hulk'' by the Chinese media due to its appearance. Design and development The development of CR200J is initiated by China Railway Corporation to create an affordable, economical, efficient higher-speed rail. The development started on 28 August 2015. First prototype started testing on 27 April 2017. Multiple trainset was sent to China Railway Chengdu Group for dynamic test on Chengdu–Chongqing railway, Chongqing–Lanzhou railway, and Chongqing–Guiyang high-speed railway between 17 December 2017 and 4 January 2018. There're multiple variants of CR200J series made by different subsidiaries of the state-owned China Rai ...
