La Estacion Historic Area (The Old Train Station Complex) contains the Old Train Station and Railway Museum historic complex, which at some point in 1884 formed the largest rail hub and warehouses in all Latin America. The complex is adorned with dancing fountains, a railway plaza and original locomotives and monuments. It was in this complex that the first locomotive completely manufactured in Mexico was made. It symbolizes the progress of the city and its transformation from the rural to an emergent industrial economy. The rail factories supplied with railways and locomotives to whole of Mexico and Central America. The Train Station is also historic due to its unusual (for Mexico) English architectural style. The Alameda avenue, the railway hangars, the factory complexes, and its surrounding housing have been proposed to be placed in the list of UNESCO World Heritage Sites.
