Icyuma cya StE500

Icyuma cyubaka ikiraro DIN StE500 icyuma gikoreshwa cyane cyane mugukora ibyuma byubatswe byikiraro bisobekeranye, nkibiraro byumuhanda, ibiraro bya gari ya moshi, ibiraro byinyanja, ibirenga, viaducts hamwe na crane nini yo hejuru. DIN StE500 isahani yicyuma, E urwego rwicyuma cyikiraro gikwiranye nibice byubatswe byikiraro bigoye kandi bikaze mubushyuhe buke hamwe nubukonje bukabije cyangwa bitwara imitwaro yingirakamaro hamwe ningufu zikomeye kandi zikomeye.
