Streetcars provide fixed route transportation using electric vehicles running on steel rails. They have been in use since the late 19th century. Streetcars can encourage development and shape city growth by connecting inner cities to new housing, employment, and entertainment. Many cities have recently restored or implemented streetcar systems to aid development, tourism, and mobility. Streetcar projects typically cost $3.5-5.5 million per mile to build and less than bus systems to operate, with funding coming from various government and local sources.
