Posted by R36 #9346 on Tue Feb 14 17:10:16 2012, in response to Re: Lawmakers: southern Queens commuters need a new railway more than the QueensWay, posted by randyo on Tue Feb 14 14:48:59 2012. It's okay, since the Rockaway line's tracks already have their own zero point, near Borden Avenue and 2nd Street in Long Island City. The tracks from the Rockaway line to Queens Boulevard would simply be tied to that same zero point going up the line, then once they cross the LIRR, they'll be reverse tied to the point where they meet the Queens Blvd line.For instance, the north end of the southbound platform at the Aqueduct-North Conduit station is located at station 480+20, or 48,020 feet (approximately 9.1 miles) from the zero point in Long Island City. It crosses Liberty Avenue 4,560 feet north from that, or station 434+60. It crosses the LIRR Lower Montauk line just north of Union Turnpike, at about 331+00±, leaving the path the line is tied to, and continuing north. It crosses the LIRR main line 21,700 feet from Aqueduct, or 263+20. If it then followed 65th Road to get to the Queens Boulevard line, it would get there approximately 23,180 feet from Aqueduct, or station 248+40. So the new chaining would be picked up either right as the Rockaway line splits from the Queens Boulevard line (reverse tied from L.M.), or as the line crosses the Lower Montauk. Approximate position of certain stations along this route: 101st Avenue: 425+75 to 418+74 Atlantic Avenue: 402+00 ± Jamaica Avenue: 380+48 ± Union Turnpike: 332+58 ± |
