Garrison, New York
Here we see a northbound Metro North commuter train making its stop at Garrison, New York. This is on the Hudson Line, which was formerly of the New York Central and later Penn Central.
The locomotive is interesting in that this model was built specifically for the tunnel to, and the bowels of, Grand Central Terminal. The unit can run on diesel but also from the third-rail (to eliminate fumes). I believe the New Haven was the first owner, one of the three railroads which were folded into the Penn Central.
