In progressionem de Sinis scriptor ferriviarum locomotives abiit per quattuor clavem gradus, assequendum leapfrog breakthrough a technology introductio ad independens innovation.
I. De Vapor LocoMotive Era (1950 - 1980s)
Post conditiones populi scriptor rem publicam de Sina, vapor locomotives factus pelagus vis in ferriviaria translationem. In MCMLII, in Sifang Locomotive & Rolling Stock Factory produci primum JF Steam motivus per imitantes in Soviet Ma type motivum, cum a maximam celeritate LXXX chiliometrorum per hora. Per MCMLX, a totalis CDLV unitates fuerat fabricari. In MCMLVI, deinceps Type (QJ) Steam motiva independenter disposito per Dalian Factory factus est maxime productum (4,708 unitates) et potens Mainline Suspendisse per hora. Hoc erat in ministerium usque MCMLXXXVIII cum productio cessavit. Per idem tempus, ibi erant et constructione type (JS) (cum celeritas LXXXV chiliometrorum per hora et cumulativo productionem 1,916 unitates) et flumina, quae formatae in exemplum et in vapore.
II. Era De Diesel Locomotives (nuper 1950 - mane 21st Century
Et Dongfeng IV Diesel motivum in introducta in MCMLXX et upgraded ad Dongfeng 4b in MCMLXXXII, becoming maxime productum (super 4,500 unitatibus) et late usus exemplar in historia Sinis scriptor Railways. In viatoribus onerariam sector, in Dongfeng-XI quasi-summus celeritas motivum, developed in MCMXCII, potest pervenire celeritate CLXX chiliometrorum per hora et ad trahendum impedimenta in Guangzhou-Shenzhen linea. Et Beijing-genus hydrau transmissionem motivum (cum celeritate CXX chiliometrorum per hora) et Dongfanghong seriem (ut Dongfanghong I viatoribus Locomotive) sunt etiam momenti repraesentativis.
III. Et era of Electric Locomotives (1960s - mane 21st Century
In MCMLXIX, in SS1 electrica motivum erat massa, produci cum continua potentia 3,780 KW et summa DCCCXXVI unitates sunt fabricativaribus, pono fundamentum in domesticis electrica locomotives. In MCMXCIV, in SS8 (SS8) pervenit in test celeritate CCXL kilometers per hora, becoming the celerrime electrica motivum in Sina in illo tempore. In principio 21st Century, harmonia seriem (HXD) electrica localized per technology introduction, covering et feugiat et summus celeritate viatoribus onerariis.
IV. Et Era of High-SPEE EMUS (21 saeculo ad praesens)
De harmonia (CHH series), quae produci per introducendis technology in MMIV, habet a disposito celeritas CC ad CCCL kilometers per hora et includit exempla monstrabit ut CH1 (Bombardier Technology) et CH2 (Kawasaki Technology). In MMXVII, in fuxing bullet impedimenta (cr Series) cum omnino independens intellectualis proprietas iura in operationem. The CR400AF/BF models have a speed of 350 kilometers per hour, achieving intelligence and high reliability, and have also given rise to special models such as the high-cold type 2 3 8. In the field of maglev, the Shanghai Maglev demonstration line (with a speed of 430 kilometers per hour) and the domestically produced 600-kilometer-per-hour high-speed maglev test vehicle (rolled off the production Versus in MMXXI) Mark secans-extremis exploratio.
Ex difficile initium vapor locomotives ad global ducens situ ex fuxing bullet impedimenta, Sinis scriptor ferriviarum locomotives formavit a plena range of products operimentum conventional celeritate, summus celeritate et gravibus-boly. In futuro, in investigationis et progressionem CR450 altius-celeritate impedimenta et permanere ad agitare industria innovation
