With a long whistleblowing, echoing from the valley sides, the two german Pacifics are celebrating reaching the end of the southern ascent to the Gotthard tunnel, when crossing the river Ticino on the Stalvedro viaduct near Airolo. Coalfired two cylinder version 01 202 is based in Lyss/Switzerland, oilfired three cylinder 01 1066 belongs to Ulmer Eisenbahnfreunde (friends of the railroad Ulm) in Germany. The steamtrain of IGE run over the Gotthard line for the 125th anniversary celebration.
