Tak\u00fdmto sp\u00f4sobom bolo zabezpe\u010den\u00e9, \u017ee \u0165a\u017en\u00e9 jednotky boli na ka\u017edom \u0165a\u017enom vozidle pou\u017e\u00edvan\u00e9 rovnako \u010dasto.

Oh\u013eadom jazdn\u00e9ho v\u00fdkonu sk\u00fa\u0161obn\u00fdch vozidiel sa nov\u00fd Actros Euro VI musel vysporiada\u0165 s drobnou nev\u00fdhodou.
