I think I saw the one you posted below, too. Here's the site that has both, and fourteen more.
I was mistaken, too, about that spur line, where the overturned rail car had been stopped. I thought that spur was unused, because some of the images, especially on Google Maps, showed the rails covered in dirt, ties covered or missing, and tractor-trailer rigs parked on the tracks behind the buildings.
The tracks must have been at least partially usable or that filled rail car wouldn't have been there, whether to be filled or offloading.
The gray-roofed building appears to be the one that blew up, and you can place its relative location from those aftermath aerials that show that curve in the road to the west. Here it is in Google Maps:

It's mind-blowing what it did to everything, including those rails. They didn't break apart, just pinched together for width of the explosion. I have wondered if the raised bed might have deflected some of the blast and shockwave, such that the apartments didn't get the absolute full force of it all. I know it's not much, yet rail beds are often at least six feet at their peaks, if not higher. Google's Terrain maps aren't detailed enough for me to see elevations.
