The impressive engine of the Concordia has been working for almost a century now. As soon as tourists embark on this steamship, they realize, to their surprise, that this is no common boat, with its extraordinary roaring steam engine, the fires of the boiler, the movement of the three huge piston-rods and the paddle-wheels that are visible through glass panes.
Its twin Patria, out of commission since 1990, is absolutely identical.

At full blast, the piston-rods make 61 revolutions per minute, speeding the boat up to a maximum of 23 km/h, with a power of 600 steam horses. The four furnaces, which were coal-fired until 1951,
produce 3 tons of steam per hour.

The steam distribution system by means of Caprotti valves (Concordia and Patria are the only boats left in the world to feature this apparatus), is considered to be the highest level of evolution of steam engines: it reduces consumption while increasing, at the same time, power and manoeuvrability. Engine capacity reaches almost...
two million cm3.

Three rare pictures taken from the driver’s position. On the left: pressure gauges. Middle: the boilers. It takes five hours to reach the pressure needed for operating the boat. This means that the stoker has to light the furnace at 4:00 a.m. to be able to depart at 9:00 a.m. to effectuate the habitual excursion from Como to Colico.

The B piston-rod bears the following inscription: Regia Italia Genova, 22 luglio 1926 (Royal Italy Genoa. July 22, 1926).
