100 Years Of The New York Subway

摘要

New York's metro celebrates its centenary this year. The Subway, as New Yorkers have been calling it for generations, may not be the world's oldest metro (that distinction falls to London Underground), busiest (Moscow, with 3.2 billion annual riders, carries more than twice as many as New York), or longest in terms of route-km (London wins again), but it is arguably unique among its peers. You can assess the New York Subway in purely numerical terms―track-km (1377), daily trains operated (6700), employees (48,000), annual capital investment ($US 2 billion), even objects as obscure as signal relays (327,156) or track circuits (11,646)―but you wouldn't be doing it justice.
