Example of a "Modern" (1919) Local Elevated Station
This photo, taken this morning at 7:10 am is at the Avenue "P" "subway" station at Avenue P and McDonald Avenue on the IND Culver Line (F-Train). The shot is from the Manhattan bound platform looking south towards the Kings Highway express station. The Avenue "P" station is a three track station with two local tracks and one express track. The reconstruction of the 3rd Avenue El around this time (1914-16) added a third track. Many of the local stations on the 3rd Avenue El had a similar configeration, but the express stops in many of the Manhattan stations were built above the local tracks. 19th Century elevated construction used a lighter, lattice type of steel construction compared to the 1919 elevated station shown here in the picture. On three track elevated structures, the express track may have express service in the direction of heavy traffic. For the 3rd Avenue Line, there was express service southbound in the morning and northbound in the evening. On the IND Culver Line, when express service existed around 1968 to 1974, express service was available using the middle track northbound in the morning and southbound in the evening. At this location on McDonald Avenue and Avenue "P", some form of rapid transit existed since 1875 and continues to today. The former railroad tracks that became trolley tracks under the structure are long gone.

Better example has been given of 1919.
ReplyDeleteSample Analysis
Hi Jaylen:
ReplyDeleteThanks for your feedback and your attachments on sammple analysis. You could say that my "sample" was a "convenience sample with a N = 1". I remember a statistics professor mentioning this to me many years ago. I picked Avenue P because it is the station that I go to work in the morning and my co-traveller had his cell phone with him and I asked him to take a photo and E-mail to me as a test yesterday morning and nothing more. It so happens that the Avenue P station was opened in 1919 and is typical of many of the elevated stations, in the Bronx, Brooklyn and Queens that openned around that time. Many of the local three track stations on the F-train in Brooklyn and the D train on New Utrecht Avenue and the Number 4 Lexington Woodlawn line in the Bronx look the same way.
Thanks for your input:
