 It is also possible to see some works done by the ancient inhabitants of these towns and villages such as the Colonial Bridge of Izcuchaca, the thermal baths of Aguas Calientes, the rustic stations and the spectacular road engineering of the railway.The line is known as "El Tren Macho" (The Male Train) because some years ago the line did not have the best technical attention and a local creative legend evolved suggesting that the train “leaves when he wants and arrives when he can”!Tha service in summer 2019 is 3 trains per week using locomotive hauled trains with buffet and 1st class coaches, the buffet class being superior to 1st class.
