The former german express train steamlocomotive 01 # 202 of association "Pacific 01 202" at Lyss, made a test run after several boiler works (replacing of stay bolts etc.), renewal of a coupling rod bearing and boiler inspection. The 4-6-2 leaves the 277 meter long St-Sulpice tunnel in a grade of 2.4 % on the line from Neuchâtel-Travers to Les Verrières, with only light load of 2 cars. On this "international" line from Berne to Paris, the tunnels have all the clearances profile for two tracks, but there was never built a second one.
