Streetcars: The Flexible Rail Transit Mode
As an experienced designer of streetcar systems, one question I am frequently asked is, "Can a streetcar _____?" The blanks are usually filled with design challenges, such as "turn left from a curb lane", or "go under a low clearance underpass" or "operate at higher speeds and frequencies." More often than not, the answer is YES! Modern streetcar systems, such as those operating in Seattle, Tucson, and Atlanta, are modeled after European trams that are designed to fit within tight, complex, and built-out urban environments. The unique combination of vehicle's size coupled with the ability to operate in the same lanes as automobiles, trucks, and buses allow designers to create safe, efficient solutions to nearly every design challenge that arises.
