Swiss Federal Railway Eb 3/5


In 1910, the Swiss Federal Railways had a need for a powerful tank-locomotive.  Either for the suburban shuttle service trains or as an assisting locomotive on short, but steep grades.  The design of the well known superheated B 3/4 locomotive was changed by replacing a separate tender for a coal bunker and water tank on the main frame supported by a carrying axle.  Thirty-four locomotives were built in 1911 and maintained in service for number of years.
