Huge passenger train shed, roundhouse, turntable, mostly electrified? Looks like Europe to me. Cannot get GE at work, so I can't search!
I guess the electrification led me to think Western Europe. The clay tile roofs are much too prevalent--at first, I thought NE Corridor.
Congratulations Otto Yard. Enfield Yard - Sydney, Australia This was a user-submitted location. Thanks to Colonel (Paul) for the good location.
I should have known. That is where I first saw the bulldogs (engines). It is a large yard, but it also looks like several of the tracks have been removed. There is an engine refueling part of this yard, too. I'll see if I can find my pictures.
The refuelling area is above the yard to the left in the image. The vacant area between them is supposedly slated for a huge intermodal area one day.
