There were once five of these shunting locomotives from 1961. But they differ in looks and performance. This one still exists and is in use at a branch of an army logistics base. But maybe not for much longer. It is replaced, and is to be sold. The locomotive is well maintained and powerful. On level ground it moves 1000 tons at 5 km/h (photo 3). Because it is a unique piece the maintenance is difficult. Each part must be certified. This shunter is now always outside. Because the replacement locomotive is already waiting in the shed. A revised SBB Tm IV, also in yellow livery. However, this no longer achieves the performance of the old locomotive. Switzerland, September 30, 2022. (1/8)
