It won't difficult for traveller and visitors to explore Portland by the public transport. Among them Portland Streetcar is the best option for all levels of travellers. Portland Streetcar began service July 20, 2001 with a 2.4-mile alignment (4.8-miles round trip) from Portland State University to NW 23rd Avenue. Now, after 15 years, 5 extensions, and over 49 million riders, Portland Streetcar operates three lines around 16-miles of track in Portland's Central City.
The majority of the line runs along pairs of one-way streets, separated by one or two blocks. Total one-way mileage for the complete loop is currently 7.2. Much of the line operates within TriMet's "fareless square" zone in the downtown area, so most trips are actually free to riders. Portland made use of an off-the-shelf European streetcar vehicle design, providing a modern, air-conditioned vehicle with level boarding.
