0-6-0 T Ed 3/3 # 4 "SCHWYZ" is by far the oldest steamlocomotive of the Dampfbahn-Verein Zürcher Oberland (DVZO). She was built in 1887 by Emil Kessler/Esslingen/Germany for the Wädenswil-Einsiedeln Bahn, which became the Schweizerische Südostbahn (SOB) later, with the steep grades of up to 5.0 %. The 350 horsepower locomotive was exhibited in Wädenswil from 1976, but could be made operational again by the DVZO in 2007. Here, the locomotive is entering Buama with the evening train from Hinwil. During the last winter, there were found severe boiler damages (haggared stay bolts) and she is waiting for repair now in Uster.
