Kev txhim kho ntawm Tuam Tshoj txoj kev tsheb nqaj hlau cov tsheb ciav hlau tau dhau los ntawm plaub theem tseem ceeb, ua tiav ib qho kev ua tiav leadthrough ntawm kev ua haujlwm ywj siab.
I. Lub Chav Laij Teb Chaw Tsim (1950s - 1980s)
Tom qab lub tswv yim ntawm cov neeg lub koom pheej ntawm Tuam Tshoj, Chav locomotives tau dhau los ua lub zog loj hauv kev thauj mus los hauv kev thauj khoom thauj. Xyoo 1952, lub Sifang locomotive & dov cov khoom lag luam tsim ua ntej jf chav todomotive los ntawm kev ua kom nrawm rau hauv locomotive, nrog qhov ceev tshaj plaws ntawm 80 km ib teev. Los ntawm 1960, tag nrho ntawm 455 units tau tsim. Xyoo 1956, Hom pem hauv ntej (QJ) Chav locomotive tus kheej tsim los ntawm Dalian Hoobkas los ua qhov ceev ntawm Suav teb, nrog kev ceev ntawm 80 km. Nws yog nyob rau hauv cov kev pab kom txog thaum 1988 thaum ntau lawm tsum. Nyob rau tib lub sijhawm, tseem muaj hom kev tsim kho (JS) (nrog hom ceev hauv 1,916 chav nyob (SY) kev siv cov qauv, uas tsim cov qauv tseem ceeb ntawm lub hnub nyoog.
Ii. Lub caij nyoog ntawm Diesel locomotives (lig xyoo 1950 - Xyoo pua 21st
Dongfeng 4 diesel locomotive tau qhia nyob rau hauv 1970 thiab hloov kho rau Dongfeng 4b xyoo 1982, dhau los ua qauv hauv tebchaws Suav teb txoj kev tsheb nqaj hlau railways. Nyob rau hauv cov neeg caij tsheb thauj kev lag luam, Dongfeng-11 Qiai-high-high-high-high-high-high-kev ceev ib teev ib teev thiab siv los rub cov tsheb ciav hlau ntawm Guangzhou-Shenzhen kab. Lub Beijing-ntaus tsheb kauj vab hydraulic
III. Lub Era ntawm Cov Hluav Taws Xob Hluav Taws Xob (1960 - Lub xyoo pua 21st
Xyoo 1969, SS1 Electric locomotive yog pawg-txuas ntxiv ntawm 3,780 kW thiab tag nrho ntawm 826 chav nyob, tso lub hauv paus rau cov hluav taws xob hluav taws xob. Xyoo 1994, SS8 (SS8 (SS8) tau mus txog qhov ntsuas nrawm ntawm 24 teev ib teev, dhau los ua cov hluav taws xob nrawm nrawm hauv Suav teb thaum lub sijhawm ntawd. Thaum pib ntawm lub xyoo pua 21st, HXD) cov khoom sib raug zoo tau ua rau muaj kev thauj khoom lag luam thiab kev thauj khoom siab.
IV. Lub sijhawm ntawm kev ceev emus emus (21st xyoo los qhia)
Qhov kev sib raug zoo (CRH series), uas yog tsim los ntawm kev qhia thev naus laus zis hauv 200 txog rau CH1 (Bombardier Technology) thiab CRH2 (kawasaki thev naus laus zis). Nyob rau hauv 2017, fuxing cov tsheb ciav hlau (CR Series) nrog cov khoom ntiag tug uas ywj pheej tau txais kev coj ua haujlwm. CR400F / BF qauv muaj qhov nrawm ntawm 350 mais hauv ib teev, ua tiav rau cov qauv tshwj xeeb uas muaj kev sib tw ua ke, thiab muaj kev ua haujlwm siab rau 600-mais kev sib tw tsheb Cov kab ntau lawm hauv 2021) Cim kev tshawb nrhiav-ntug kev tshawb nrhiav.
Los ntawm qhov nyuaj pib ntawm chav locomotives rau lub ntiaj teb ua txoj hauj lwm ntawm fuxing cov tsheb kauj vab tau tsim muaj ntau cov khoom uas npog cov pa hluav taws xob, qhov siab nrawm thiab hnyav. Nyob rau yav tom ntej, kev tshawb fawb thiab kev txhim kho ntawm CR450 ntau dua-cov tsheb ciav hlau yuav txuas ntxiv tsav tsheb lag luam tshiab
