I-SD70M-2 yakakura kubva pakudiwa kweEEM kuti iite zvinoenderana nemitemo itsva yeTyer II muUnited States.
Kunyange zvazvo kuvandudzwa kwemukati kweD7070M yakapfuura kwaiva duku, nzvimbo yakasimuka yakabuda nefomu rutsva nemotokari. Kunyange zvazvo chirongwa chakaparadzanisa zvachose kubva ku-2 kukura kwema1970, SD70M-2 yakafanana neshanduro yakavandudzwa ye SD70M.
Saizvozvowo pakuonekwa kune SD70ACe, SD70M-2 inonzi DC traction motor yakafanana. Iko kunonyanya kuonekwa pane ibhokisi rinotenderera riri shure kwekate pane rutivi rwomutevedzeri weuniti paA AC, (yakafukidzwa pamusoro peM-2.)
Kubvira pakuiswa kwezvikwata izvi, GM yakatengesa EMD. Muvaki ikozvino chikamu cheProgress Rail. Kuonekwa kwezvivako hazvina kuchinja kunze kwomuti wejasi.
Simba guru re SD70M-2 ndiro General Electric ES44DC. GE's "Evolution" yemuenzaniso yakadarika SD70M-2 mukutengesa uye, nechinangwa chechina chechina chaisati chagadzirirwa kubva kuProgress Rail kusvikira muna 2017, GE yakagadzirira kuwedzera iyo mutungamiri.
Apo mutsara weD7070 wakatanga kubudiswa mumavambo ekuma1990, AC inotengesa motors yaiva chimwe chinhu chechimwe chinhu.
Kutengeswa kweS SD70 uye SD70M kwakaenzanisa zvakanaka ne SD70MAC. Ne 331 SD70M-2s chete inofananidzwa ne-1100 SD70ACe zvakajeka kuti AC motokari iri pano kuti igare.
Canada National and Norfolk Southern inoshandisa zvikepe zvakakura zvezvivako zvekare. Florida East Coast yakabhadhara 11 SD70M-2s asi muna 2015 yakatanga kutora zvitsva zveG GE zvinoshambadzira - yekutanga kwemafirimu EMD kwenguva refu.
Nenzira dzepamutemo Mapurisa emagetsi anowanzoshanda zvishoma nezvishoma "kudhonza" zvidzitiro sematokari emarasha, ane maDC anopiwa kunotengesa zvakakurumidza. SD70M-2s inofanirwa kugoverwa kumidzitiro yemasikirati uye yakavhenganiswa mitoro. Kukura kukuru kwemalahle uye unit unit namafuta ethanol mumakore gumi apfuura zvinobatsira kutsanangura kuchinja kune simba AC. Mafurati anotenderera kumatokisi akasiyana asi uye nguva dzose anobva kune imwe yereji kuenda kune imwe. Iyi "simba rekune imwe nyika" inobatsira kusika mamwe mavara anowanikwa panguva iyo mawikiti ivo pachawo anotarisa zvakanyanya kufanana mumigwagwa yose.
Nezvinodiwa zvitsva zvinokonzera kuti zvigone kushanda, hazvikwanisiki zvakare SD70M-2s ichavakwa - kunyanya kuNorth America service. Kubva muna 2015, mumwe anotsiva achiri muchigadzirwa chigadzirwa. Kunyange zvakadaro, chero bedzi ichiratidza sechinhu chakavimbika seicho chakauya, zvinoita sokuti SD70M-2 ichave yakapoteredza kwemakore akawanda ari kuuya.
