Dona Joaninha

Dona Joaninha is a black metal locomotive with a 2-6-4 wheel arrangement weighing 150 tonnes, displayed at Praca Paschoal Thomeu. The engine features a boiler, water tank, and sturdy construction designed for transporting sugar cane across rail routes.

The locomotive was manufactured by Bottene & Filhos in 1940 and transported sugar cane between Tamoio station and Araraquara until operations stopped in the 1960s. Its decline came as rail routes were gradually abandoned.

The locomotive is named after Dona Joana Morganti, who owned the workshop where workers assembled this engine from various parts. Visitors can today see the craftsmanship of that assembly reflected in the machine's structure.

The locomotive is accessible daily behind protective railings at the plaza. Evening lighting installed during the 2020 restoration makes it easy to see the machine's details when visiting after sunset.

The locomotive was built using components from an earlier rail engine, including its chassis and wheels, while the boiler and water tank were newly manufactured. This unconventional assembly makes it a rare example of industrial improvisation in Brazil.
