I didn't find that on the sites I use. However, I did find other coil cars. There are 2 on the DLS that are the sake design, but one is on red and another in black. Also, good Evans coil cars can be found here: http://rrmods.com/evans.shtml
That looks exactly, or similar to, the NS one you want. The one in the screenshot MIGHT be a personal reskin though. They look like they have Jointed Rail quality trucks on them too.
