as well as from cities around the world. In March 2000, service on the F line began along the new extension to Fisherman's Wharf. The E Embarcadero became San Francisco's second heritage streetcar line in 2016. The line runs along the entire length of the Embarcadero, along existing track used by the F Market & Wharves historic streetcar and the N Judah and T Third Street Muni Metro lines. Initial service will run from Jones Street and Jefferson Street in Fisherman's Wharf to the Caltrain station. The line will be extended west past Aquatic Park and through an unused railroad tunnel to Fort Mason. Exploratorium The Exploratorium is a museum in San Francisco that has created over 1,000 participatory exhibits that mix science and art, all of which are made onsite. It is considered by some to be the prototype for participatory museums around the world. On January 2, 2013, the Exploratorium closed its doors to the public at the Palace of Fine Arts and began its move to a new location on Piers 15 and 17 along The Embarcadero. The museum opened to the public at Pier 15 on April 17, 2013. Cruise Terminal The new James R. Herman Cruise Terminal at Pier 27 opened in August 2014 as a replacement to Pier 35. The modern terminal has electric shore power, larger holding areas, and secure customs screening. Pier 35 had neither the sufficient capacity to allow for the increasing length and passenger capacity of new cruise ships nor the amenities needed for an international cruise terminal. The port currently handles sixty to eighty cruise ship calls and 200,000 passengers and expects an increase to 300,000 in 2015. Itineraries from San Francisco include round trip cruises to Alaska and Hawaii. So far, the Queen Mary 2 is the largest cruise ship that docked in San Francisco. On March 16, 2013, Princess Cruises Grand Princess became the first ship to home port in San Francisco year round. The ship offered cruises to Alaska, California Coasts, Hawaii, and Mexico. In 2018, the Port of San Francisco was expected to meet three cruise ships for the first time: the Silver Explorer, Ponant's Le Soléal, and the new Norwegian Bliss that will become the largest ship to visit the city.
