Best Trainz Routes (free or paid) to mimic Grand Canyon Railway?

I am trying to make a "model" (not prototypical, but an imaginative version of) the Grand Canyon Railway and am currently looking for routes that best mimic the basic look of the GCRy that I can add to (such as the South Rim, Williams depot, etc.). I'm just now downloading the dependencies for Cajon Pass Xtreme but just looking over the baseboards for it, I'm not sure it really looks like Arizona without a massive amount of reworking to the point that I might as well just build an exact copy from scratch, and I definitely don't have the focus/time for that unfortunately. The other route I'm considering is JR's Mojave Sub and I don't have an issue spending the $25 for it but I don't want to spend that to end up with a route that doesn't have what I'm looking for, and the Trainz Store doesn't have a *ton* of information on what the route actually looks like. Any ideas out there? Thanks in advance, Trainz community!
