With tilting EMUs, consideration is required on keeping the pantographs within the railway gauge. When mounted on top of a tilting car, the pantograph usually sways in the opposite direction in order to counter for the degree of tilting. This is done mechanically on for instance the British Class 390 Alstom Pendolino. On the German class 411 and 415, the pantographs are however mounted on a separate non-tilting frame within the cars.
