At the open day at the SBB's Biel industrial plant to celebrate 175 years of Swiss Railways, snow blowers from five generations were displayed and demonstrated. Here, the turning is done on the spot, either by means of a slewing ring on the frame, or with a built-in lifting device. On the left, the three-axle Xrot m # 98, built in 1968 by SLM Winterthur. On the right, the smaller XTm # 109 built by Aebi.
