A couple of years ago, about the time they first came out, I purchased two of the Athearn RTR SD45T-2's, cause they are neat and have the see thru grill and I wanted them.
Of course, modeling more current UP was a problem cause they no longer had any on their roster. This year however, they picked up one (1) from LTEX. So, now I'm golden, running one on the layout.
Thank you UP.
