Ukuthuthukiswa kwe-China Railway Locomotives kudlule ezigabeni ezine ezibalulekile, ukufeza ukuphumelela kwe-leapfrog kusuka ku-Technology Isingeniso ekubuseni okuzimele.
I. I-Steam Locomotive Era (1950s - 1980s)
Ngemuva kokusungulwa kweRiphabhulikhi Yabantu baseChina, izithonjana zeSteam zaphenduka amandla amakhulu ekuhanjisweni kwesitimela. Ngo-1952, ifektri ye-Sifang Locomotive & Story Stock ikhiqize i-JF Steam Locomotive yokuqala ngokulingisa uhlobo lweSoviet Macomotive, ngesivinini esikhulu samakhilomitha angama-80 ngehora. Ngo-1960, kwakhiqizwa amayunithi angama-455. Ngo-1956, uhlobo lwaphambilini (qj) i-somecomotive ye-Steam eklanywe ngokuzimele yi-Dalian Factory yaba amayunithi akhiqizwe kakhulu (ama-4,708 amayunithi) kanye ne-mainline freight locomotive eChina, ngejubane lamakhilomitha angama-80 ngehora. Bekusenkonzweni kuze kube ngu-1988 lapho ukukhiqizwa kuphelile. Ngesikhathi esifanayo, kwakukhona futhi nohlobo lokwakha (JS) (ngejubane lamakhilomitha angama-85 ngehora kanye nokukhiqizwa kwamayunithi angama-1,916) nohlobo lwezokumbiwa phansi, okwakha amamodeli aphezulu we-Steam Age.
II. Inkathi ye-Diesel Locomotives (ngasekupheleni kwawo-1950s - ekuqaleni kwekhulu lama-21
I-Dongfeng 4 Diesel Locomotive yethulwe ngo-1970 futhi yathuthukiswa ku-Dongfeng 4B ngo-1982, iba amayunithi akhiqizwe kakhulu (angaphezu kuka-4 500) futhi isetshenziswa kabanzi imodeli emlandweni wesitimela waseChina. Emkhakheni wezokuThutha wabagibeli, i-dongfeng-11 quasi-high-speed locomotive, yathuthukiswa ngo-1992, ingafinyelela ijubane lamakhilomitha ayi-170 ngehora futhi isetshenziselwa ukudonsa izitimela kulayini weGuangzhou-Shenzhen. I-Beijing-Type Hydraulic Transfession Locomotive (ngejubane lamakhilomitha ayi-120 ngehora) nochungechunge lwe-Dongfanghong (njenge-Dongfanghong 1 Locomotive) nabo abamele abamele.
III. Inkathi yezindawo zikagesi (1960s - ekuqaleni kwekhulu lama-21
Ngo-1969, i-SS1 Electric Locomotive yayikhiqizwa kakhulu ngamandla aqhubekayo angama-3,780 kW kanye namayunithi angama-826 akhiqizwa, abeka isisekelo sezindawo ezifuywayo ezifuywayo. Ngo-1994, i-SS8 (SS8) yafika ngesivinini sokuhlola samakhilomitha angama-240 ngehora, iba yi-locomotive kagesi esheshayo eChina ngaleso sikhathi. Ekuqaleni kwaleli khulu lama-21, izinhlaka zikagesi zikagesi (HXD) zangezelwa ukwethulwa kwezobuchwepheshe, zimboze izidingo zombili zokuhamba zabagibeli.
IV. Inkathi ye-emus enesivinini esiphakeme (ngekhulu lama-21 ethule)
Ukuvumelana (uchungechunge lwe-CRH), olukhiqizwe ukwethula ubuchwepheshe ngo-2004, lunejubane lokuklanywa kwamakhilomitha angama-200 kuya kwangama-350 ngehora futhi luhlanganisa amamodeli anjenge-CRH1 (ubuchwepheshe bebhomu (ubuchwepheshe bawasaki). Ngo-2017, izitimela zeFuxing Bullet Trains (cr chungechunge) ngamalungelo azimele ngokuphelele empahla yempahla ehlakaniphile afakwa ekusebenzeni. Amamodeli we-CR400 BF anesivinini samakhilomitha angama-350 ngehora, afeze ubuhlakani obuphezulu, futhi anikeze amamodeli akhethekile anjengemoto ekhethekile ye-maglev. Umugqa Wokukhiqiza ngo-2021) Maka umaka ukuhlola-onqenqemeni.
Ukusuka ekuqaleni okunzima kwama-locomotives we-Steam endaweni ehamba phambili yomhlaba wonke yezitimela ze-FUXIng Bullet, izindawo ezihamba phambili zesitimela ziye zakha uhla oluphelele lwemikhiqizo ehlanganisa isivinini esijwayelekile, ijubane eliphezulu kanye nesisindo esindayo. Ngokuzayo, ucwaningo kanye nokuthuthukiswa kwezitimela eziphakeme ze-CR450 kuzoqhubeka nokushayela izimboni ezintsha
