Sitimayi ndi imodzi mwazinthu zofunika kwambiri zopangira komanso zoyendera za anthu. Kwa zaka mazana ambiri, anthu apitirizabe kupanga luso lake lamakono, ndipo luso la njanji ndi locomotives silinafike pachimake.

Lero, njanji padziko lonse lapansi zili ndi ntchito zambiri zoyendera kuposa kale, ndipo zofuna zomwe zimayikidwa kwa opanga masitima apamtunda ndi ogulitsa awo zikusintha mosalekeza. Kuzungulira kwazinthu zazifupi komanso luso laukadaulo, kugwiritsa ntchito zatsopano, zapamwamba kwambiri, chopepuka, zambiri zopulumutsa mphamvu komanso zoteteza chilengedwe, ndipo ngakhale kugawikana kosalekeza kwa ntchito kumafunikira luso lopitilirabe komanso kusintha.

Mafuta Otsekera, kulowetsa ulusi wodzigudubuza komanso kutsekera makiyi kumagwiritsidwa ntchito kwambiri mumayendedwe anjanji ndi ma locomotives ngati matekinoloje atsopano komanso otsogola.. Njanji zothamanga kwambiri zikukula kwambiri m'dziko lathu, ndi ma EMU othamanga kwambiri akugwira ntchito mochuluka panjanji zazikulu zonse m'dziko lonselo ndikutumizidwa kumayiko osiyanasiyana.. Aluminiyamu alloy yakhala chinthu chachikulu pamagawo oyendetsa magalimoto chifukwa chopepuka komanso kusindikiza kwake.. Komabe, chikhalidwe chofewa cha aluminiyumu alloy zipangizo kumabweretsa kufooka kumeta ubweya kukana mu kugwirizana ulusi. Kukonzekera kwachindunji kwa ulusi pazinthu zoyambira sikungathe kukwaniritsa zofunikira zachitetezo cha msonkhano wagalimoto ya njanji ndikugwira ntchito. Aluminiyamu alloys amafuna kugwiritsa ntchito ulusi sheaths kuonetsetsa bata ndi kudalirika kwa kugwirizana.

Mu mitundu yosiyanasiyana ya ma EMU apakhomo, ulusi sheaths amagwiritsidwa ntchito mumitundu yosiyanasiyana yolumikizira monga zamkati zamagalimoto, kuyimitsidwa kwakunja, ndi kukweza pansi pagalimoto. Mitundu ikuluikulu imaphatikizapo zolowetsa ulusi wa waya, zolowetsa ulusi wodzigunda, ndi zoyikapo ulusi wokhoma makiyi. CRH1 EMU ili ndi thupi lachitsulo chosapanga dzimbiri ndipo silifuna kugwiritsa ntchito ulusi wa ulusi; CRH2 EMU makamaka imagwiritsa ntchito zida zachitsulo; CRH3 EMU makamaka imagwiritsa ntchito zoyikapo paokha, ndipo amagwiritsidwanso ntchito polumikizira mapaipi amitundu yayikulu. Kuyika kwa ulusi wa waya kumagwiritsidwa ntchito pazigawo; makiyi otsekera ulusi amagwiritsidwa ntchito mu CRH5 EMUs.
