Originally delivered to the S e S for passenger service, these engines remained in service until the end of steam on the Companhia dos Caminhos de Ferro Portugueses.
Class 401 (Locobase 9704)
Data from [], last accessed 30 November 2008.
According to Ferropedia's Spanish-language site, this sextet was a Bavarian attempt to come up with an express compound locomotive for the Portuguese Railways. As such, they strongly resembled the Bavarian Railways S 3/5 and S 3/6 designs. A 1930 photo shows an unusual shield under the smokebox that wrapped around to embrace the cylinders. The steam dome sat well forward, ahead of the sand dome, and the cab had a "wind-splitter" wedge-shaped face.
After 30 years in Portuguese service, the Lisbon shops added superheaters to the boilers. The first of the class - 403 - retired on 20 February 1952. The others left service over the next 9 years with 406 making the final exit on 21 July 1961.
