Traveling on the CP Historic Tua Steam Train is  a journey  in time. The locomotive and classic cars snakes along the Douro River with sweeping views of the surrounding valley and wine country. The  0186 steam engine was built in 1925 by Henschel & Son and pulls five historic wooden carriages. Runs in the summer from Peso da Régua to the  Tua River, passing through Pinhão. Runs June to October.
