Transit projects I think would be fun:

• Cincinnati Streetcar Extension
• Louisville Light Rail
• Chicago Loop Line
• Septa rebuild of those trolleys that were destroyed in that fire
• Red Line, Baltimore
• Atlanta beltline streetcar
• Raleigh Durham Light Rail
• Buffalo Subway extension to the University of Buffalo
