The elegant vehicle, built in 1939, is decorated for Advent and Christmas, on the one hand with an LED strip on the edge of the roof and in the lower box area, and on the other hand on the front with a fir branch-Christmas tree ball-candle motif. The "Churchill-Pfeil", which name comes from former british prime minister Sir Winston Churchill, which travelled in it during his visit in Switzerland in 1946, is ready for departure in Winterthur.
