Though few amassed a great deal of wealth, the city prospered due to Joseph Folsom's lobbying to get a railway to connect the town with Sacramento. Joseph died in 1855, and Granite City was later renamed Folsom in his honor. The railway was abandoned in the 1980s but opened up as the terminus of the Gold Line of Sacramento Regional Transit District's light rail service in 2005.
