Could easily still have screwed up signaling and signages, but at least from what has been seen it's promising. And in terms of the look of the route I think this is the best looking version of the route a good margin. Also, Tehachapi Pass been done too many times in other train simulation games.
On paper I think this is the strongest route DTG have made for the US in a while, lots of stock, good length, and plenty of possibilities for use of stock from ATSF and SP by scenario makers. I doubt Tehachapi Pass will be done for Train Sim World (at least from Dovetail Games) because 3DTrains is making a payware version for Train Simulator 2018 and the BNSF licensing restriction is still in effect.
Also while it gets detours the lines doesn't usually have passenger service, so I would much rather have another freight locomotive than the P42 all things considered. But you're talking about two hours end to end in a straight run, plus a few yards, industries, and sidings which provide quite a few possibilities for scenario makers. The included scenarios I imagine won't take full advantage of the length knowing DTG.
