The Old Train Station and Railway Museum is located in the city of Aguascalientes, in the state of Aguascalientes, in Mexico. Aguascalientes was once the largest hub in Mexico's rail system, and it held the largest workshop and warehouse complex in all Latin America. The museum is housed in four of the forty-eight huge departments, the oldest rooms that used to be part of the railway installations and which date from the end of the 19th century.
