The MBTA commuter rail has two stops in Waltham as part of the Fitchburg-Boston Line: one in Central Square Waltham across from the City Hall and one near Brandeis University.
The original home of the Boston Manufacturing Company, the city was a prototype for 19th century industrial city planning, spawning what became known as the Waltham-Lowell system of labor and production. The city is now a center for research and higher education, home to Brandeis University and Bentley University. Waltham is commonly referred to as Watch City because of its association with the watch industry. Waltham Watch Company opened its factory in Waltham in 1854 and was the first company to make watches on an assembly line. It won the gold medal in 1876 at the Philadelphia Centennial Exposition. The company produced over 35 million watches, clocks and instruments before it closed in 1957. Waltham has in recent decades become a center for Ugandan culture, with an estimated 1500 Ugandans living in the city. Waltham embraces its ethnic diversity in a number of festivals. The annual Latinos en Accion Festival celebrates the many Puerto Rican, Mexican, Peruvian, and Guetamalan residents.
