“China-standard”EMUtrains,thelatestgenerationofhigh-speedtrains,signifythatChinahasgraspedthecoretechnologyinthisfield.ShangJingexplained,“‘China-standard’EMUtrainsweredevelopedindependentlybyourcountry.Itscoresystemis100percentdevelopedbyChina.”

“Inordertoreducenoise,wehavesetupaspecialinvestigativeresearchteam.Duringthedaywhenthetrainsareoperational,ourtechniciansanalyzethedata,andatnightwhenthetrainsareoffthetracks,theyverifyit.Wehaveimprovedthesoftwareonthetrainsover100times.”

AccordingtoShangJing,“AcompleteindustrychainhasformedinChina’shigh-speedrailindustry,includinglocomotivemanufacturing,keycomponentsandaccessoriesproduction.”

Moreimportantly,asChina’shigh-speedrailindustrygoesglobal,boththeChineseeconomyandforeigncountriesstandtobenefit.
