I have two of these in Amtrak, and seven in Santa Fe. Crude compared to the GGD cars I pull with them, but definitely worth time for an upgrade. Sadly Amtrak didn't have FP45s, but the non-turbocharged SDP40F which is very different on the detailing. However for now I can live with the good enough category.
Note that one way to make the Amtrak version a little more prototypical is to remove the handrail off the front porch. Amtrak did not have them on their fleet.
