The Railadventure company bought from the SBB the former Re 6/6 # 11603 "Wädenswil", one of the 4 prototypes of the series, built in 1972 by SLM, BBC and SAAS with 10600 Horsepower. Now it is in service in a brand new paint scheme and designated Re 620 # 003 "Schweiz Svizra Suisse Svizzera". The locomotive will be used mainly for transfer runs of brand new vehicles from the works to the costumers or to test sites, for example for StadlerRail. The locomotive is not approved to run in Germany, there RailAdventure owns several other locomotives for this purpose.
