N Judahとは 意味・読み方・使い方

The N Judah is a Muni Metro line in San Francisco, California, so called as it runs along Judah Street for much of its length, named after railroad engineer Theodore Judah. It links downtown San Francisco to the Cole Valley and Sunset neighborhoods. It is the busiest line in the Muni Metro system. It operates with high frequencies (7-12min) and mostly two-car (46m) trains during Muni Metro hours of operation. It was one of San Francisco's streetcar lines, beginning operation in 1928, and was converted to modern light rail operation with the creation of the Muni Metro system in the late 1970s. While many streetcar lines were converted to bus lines after World War II, the N Judah remained a streetcar line due to its use of the Sunset Tunnel.
