Phoenix
Phoenix got its modern rail system in December 2008, when Valley Metro light rail opened on a roughly 20 mile route linking Phoenix, Tempe, and Mesa. The line was later extended east into Mesa and northwest in Phoenix. In May 2022 the Tempe Streetcar opened near Arizona State University, and in June 2025 the South Central extension opened, running about 5.5 miles south along Central Avenue from downtown to Baseline Road. The same day the light rail split into the A and B lines, bringing it to about 35 miles.
