Posted by andy on Thu Feb 11 21:30:33 2010, in response to Question About The (8) Third Avenue El, posted by Union Turnpike on Thu Feb 11 21:11:02 2010. Most likely, the rush hour headway was six minutes. I informally calculated that a train operating between 149 and Gun Hill required 24 minutes for the entire trip (15 stations including both terminals). That would mean with a six minute terminal dwell that one consist needed exactly one hour to complete a round trip, including the dwell at the original terminal waiting for the next trip. With a six minute headway ten consists (one hour trip divided by six minute headway) would be required; eleventh one was probably a protect train. I imagine that the off peak midday, evening and Sat/Sun headway was ten minutes, requiring six trains. The unneeded ones were probably laid up on the leads north of Gun Hill Road.Eighty cars divided into five car consists equals 16 consists, providing more than enough rolling stock for the eleven required rush hour trains. |
