STATEN ISLAND HEAVY RAIL
A Single Line for Richmond Borough

The Staten Island Railway (SIR) is that borough's single passenger line, and only operating railroad.  Its route of just over fourteen miles runs between St. George, scene of this photo, and Tottenville, near the southwestern tip of the borough.  There are twenty-two stations in full-time use. 
 
The line, for a long time a division of the B&O, has for decades now been operated by the New York City Metropolitan Transportation Authority (MTA) as a separate division, apart  from the massive subway system that serves the rest of the city.
