Modern fleets, like the newer , use different alloys and monocoque designs that distribute stress better, but they are not immune. The ongoing investigation into these structural failures serves as a cautionary tale about the high cost of delayed fleet modernization.
The phrase "" (the state of bus cracking) refers to a critical structural issue within public transit fleets, particularly involving the aging Ikarus or early Modulo buses in Hungary . These cracks often appear in the chassis or "vázszerkezet," signaling that a vehicle is reaching the end of its safe operational life. The Anatomy of a Bus Crack A buszrepedГ©s ГЎllapota
