China standardized EMUs have done the most difficult test --- interoperability test. All test schemes will be finished by the end of June this year.
China standardized EMUs (One is CRH-0503#) rolled out in June 2015 with the design speed of 350 km/h. This is a key innovation project in China. The test is carrying out on Datong Datong-Xi'an railway passenger dedicated line.
There are total of 66 test item under the guidance of China Railway. The new HSTs have pass through 62 items. The remaining item will be completed before the end of June.
Interoperability test is to check the connection of two kinds of China standardized EMU respectively made by two CRRC factories, Changchun and Sifang. The two EMUs have different technical specification. They should have the function of master EMU control the slave EMU.
