A. A rough area next to the railroad tracks

 
Q. Where is it supposed to be on the show?

A.  In New York City.

Q. When did we see it on the show?

A. We see this location in Episode 2 of Season 1 of Resurrection.
 
After the Dark Passenger killer kidnaps a rideshare driver, we see a couple of young guys spraying graffiti on a low wall near the railroad tracks.

As a train rumbles by below, one teenager climbs up to what appears to be an empty lot, where a car has been abandoned.

As he approaches the car, he suddenly looks startled and the camera shows us what he sees: inside the car, the decapitated body of the rideshare driver is propped up in the driver's seat, with the disembodied head sitting on its lap.  

Q. What is it actually in real life?

A. Several lines of railroad tracks, next to the parking lot of a movie studio. 

 

Q. Where can I find it in real life?

A. These railroad tracks are right next to the Great Point Studio's pop-up studio, at 95 Woodworth Ave, in Yonkers, New York. 
 
The train tracks, which run north/south, are immediately west of the studio, and the portion of the tracks where they filmed this scene lies between Babcock Place on the north and Ashburn Ave. on the south.

The camera appears to be looking south/southwest.
 
The train tracks and the studio are just two blocks east of the Hudson River (which acts as the boundary line between New York and New Jersey). 
 
 Yonkers is about 14 miles north Manhattan
