Massachusetts Bay Transportation Authority
public transit operator in the Boston metropolitan area / From Wikipedia, the free encyclopedia
The Massachusetts Bay Transit Authority (usually called the MBTA or "the T") is Massachusetts' public transportation system.
The MBTA opened on September 2, 1897. Its first line, the Green Line, was the first subway in the Western Hemisphere.[1] At first, it connected only the Boston Public Garden to Park Street Station - about a half-mile walk.[1]
Today, all together, the parts of the MBTA travel 1392 miles each way, every day.[2]p.3
