First off, I play on PS4 pro and immediately noticed a massive step up in visuals and performance on this route. Frame rate is smooth, pop in less noticeable, seems like optimization is getting better. Both locos are a joy to drive, the gp9 is incredibly detailed. The gp38 is not just a reskin, there are significant changes, no dynamic brake, different control console and gauges etc. One newish feature is the necessity to turn on comms to supply power to the trailing locos. A huge variety in rolling stock including a few csx wagons I have not seen before, maybe from heavy haul? The new feature is unloading ethanol, this even has its own dedicated tutorial. The route is short. I mean, really short. Freight yards are sprawling however, they are massive. Only 68 services in total. The mainline services are pretty much copy paste. Personally I love it so far as I prefer freight, but I sense a lot of complaints coming from the usual suspects. Cheers.
