The facility was established in 1921 as the largest railway maintenance center in South America.
It features a unique 360-degree turntable used to pivot locomotives into specific repair bays.
Many of the original cast-iron windows and steel rafters remain in their original 1920s configuration.
The complex was constructed to house the maintenance needs for both steam locomotives and the transition to electric power starting in the 1950s.
The surrounding district developed specifically to provide housing and social services for the thousands of workers employed by the Maestranza.
La Maestranza in San Bernardo is a historical railway workshop complex that served as the primary maintenance hub for the Chilean State Railways during the 20th century. The site preserves an extensive collection of steam and electric locomotives, passenger carriages, and industrial machinery from the industrial golden age of Chile. The facility was declared a National Monument in 2004 due to its architectural and technological significance in the development of the national rail network. Visitors can explore the vast roundhouse and repair shops, which retain much of their original layout and engineering infrastructure. The site acts as an open-air museum detailing the evolution of rail transport and the social history of the workers who once resided in the surrounding neighborhood.
