From the October25, 2012, Chicago Tribune "A streetcar renaissance."
A graphic showed the loacations of existing streetcar systems and proposed ones.
"Many American cities use or are returning to streetcars to quell congestion. Some systems use modern cars, similar to the "L," while others use heritage cars (what I'd like to see) that replicate the classic appearance of older models. Some cities, such as New Orleans, San Francisco and Philadelphia, have long has streetcar systems and use a mixture of old and newer equiment."
Here is a list of cities using Heritage Systems (include some replica cars)
Little Rock, Ark.
San Jose, Cal.
San Pedro, Cal.
Fort Collins, Col.
El Reno, Oklahoma (I didn't know that and right on Route 66)
Memphis, Tn. (OK as long as they're not named after Confederates.)
