More than 10 years ago, the RUWA wire welding plant in Sumiswald took over the two Ee 3/3 electric shunting locomotives "pocket crocodiles" # 16403 and # 16408 (built 1946) from SBB in order to deliver freight cars from Sumiswald-Grünen station to the plant premises (approx. 2 kilometers) using its own resources. On November 23, 2025, the Railway Touring Company from Great Britain, together with the Bern Steam Railway Association (DBB), organized a trip with a passenger train and the two Ee 3/3 locomotives along the entire route of the Emmentalbahn from Sumiswald-Grünen to Wasen im Emmental (5.2 kilometers). Due to snow and ice, the track had to be cleared at various level crossings and the train had to be driven very carefully. The train reached Sumiswald-Grünen aganin and the Ee 3/3 # 16408 is shunting his sister # 16403 to the depot area. On the left is the tour guide of the Railway Touring Company.
