One of the six inside-cylinder 4-6-0s built for the South & South East Railway of Portugal by Henschel & Sons, Kassel, Germany in 1910, arrives at Tua with a freight train runing in the direction of Porto on a May evening in 1968. These engines were affectionately known as 'B12s' by British enthusiasts owing to their similarity to the class of Great Eastern Railway 4-6-0s of that designation.
