The steam engine running on the The Tiradentes – São João del Rei tracks was made by Baldwin Locomotive Works, in Philadelphia, in the early 20th century. It pulls the train at a speed of 30 kilometers per hour (roughly 18.6 miles per hour) on a 760 mm-gauge line.
In Brazil, steam engines like this one are informally called "Maria Fumaça", which could be translated as "Mary Smoke" or "Smoke Mary". In Minas Gerais, another popular trip aboard a Maria Fumaça is the Ouro Preto-Mariana train ride.
