Treno Blu is an Italian Tourism Railways initiative that organises trips by historic and tourism trains in spring and autumn on disused and other lines. In recent years, the service has been conducted exclusively with historic steam trains which, pulled by a puffing locomotive with period carriages dating back to the 1930s, take passengers back in time to the atmosphere of days gone by.
Train trips are often combined with a boat ride on Lake Iseo or a luncheon of typical products.
