Park Ave Tunnel

Post by mainline » Sun Aug 26, 2018 8:13 am

Does anyone know what the percent incline the railroad has to overcome? When viewed from the Harlem-125Th Street Platform looks to be a sharp increase in grade to the station.

Thanks for any info.

I have some track charts of this territory but they are buried and might not become available for a bit. I believe the highest spot is 86th Street. I can remember working train 362 back when and when we passed 86th Street we would shut off and drift all the way to Melrose. Train 362 did not stop at 125th Street but it made just about everything from Mount Vernon to New Haven and took 4 hours to do that trip.

Behind this location they must run upgrade. That is my question.



Thanks to all.

Yes, that's the viaduct rising, which begins around 97th Street. It's stone, then it becomes a steel el-type structure.

You can see some very old images on this link from Forgotten NY, showing the viaduct rising at 97 St:

It looks more drastic when viewed from the photo you shared because of foreshortening, but it's a fairly gradual rise.

Not sure but one of great historians on Hudson line (George Kowaski) told me the slight raise at MP 2.2 is highest on water level rout at something like 27 feet

Correct, 86th Street is the highest point between GCT and Albany.

Looking at that photo, does anyone know offhand how far the direct fixation track goes north and south outside of 125 St?

Southward, the direct fixation track ends at around 110th Street, where the steel viaduct ends and the stone arched structure with a ballast deck begins. Northward it extends to about 130th Street where it goes onto a ballasted deck on the approach to the Park Avenue bridge. The change in ride/sound was quite noticeable in the old (ACMU, M1-M6) equipment, not so much in the newer stuff.

Wow, that's some serious coasting... and Melrose was probably still in daylight then. Also, including the long lost Columbus Av? :-D I think there were probably a few now closed stations in CT territory, too. No wonder it took 4 hours!
