what is the oldest subway system in the us
Tremont Street Subway The Tremont Street Subway in Boston's MBTA Subway system is the oldest subway tunnel in North America and the third oldest worldwide to exclusively use electric traction (after the City and South London Railway in 1890, and the Budapest Metro's Line 1 in 1896), opening on September 1, 1897.[2][3] It was originally built to get streetcar lines off the traffic-clogged streets, instead of as a true rapid transit line. It now forms the central part of the Green Line, connecting Boylston Street to Park Street and Government Center stations.
First university in the United States Harvard University calls itself "the oldest institution of higher learning in the United States" and this claim is rarely challenged. It is possible to disagree what year should be taken as Harvard's "real" founding date (Harvard uses the earliest possible one, 1636, when the institution was chartered by the Massachusetts Bay Colony). However, Harvard has operated since 1650 under the same corporation, the "President and Fellows of Harvard College"; it thus has an unbroken institutional history dating back to the mid seventeenth century (an official Harvard web page for the School of Engineering and Applied Sciences [10] claims, "Founded in 1636, Harvard is America's oldest university").
