I've been working on a new update, and I think I'm getting close to a release. Here are the changes;

All of the mainline signals on the route have been replaced with older-style searchlights. Probably not entirely accurate to the 90's timeframe or the railroad, but I'll live. They're from RCAP so it's important that it's installed.

Throughout all of the route I've improved the foliage, with lots of desert bushes and freeware cacti.

I've also added two new sections of the route, the South City branchline to the south of Arlington, and the Western Shores branchline.

The South City has a handful of sidings to switch cars at-- this area is about the same number of sidings as the Oasis industry park, except with larger radius curves and higher capacity sidings.

The Western Shores branch climbs uphill to an oilfield on the west coast of the Starlight Sea. It's not very long or elaborate, but you might get some mileage out of running trains between here and the yard at Arlington.
There are some other minor track changes made, such as a turntable and small service yard at Lewistown. I'm hoping these changes will make running local freights or switching more enjoyable.
I haven't been slacking with the motive power, however.

High hood GP9; quick and easy paint swap. I recommend using one of these for switching, while using the low noses for the heavy hauls.

Updated paint for the RDCs; the old ones were not very good and done before I finalized the ALRR paint scheme. These will replace the current paints for both the RDC-1 and RDC-3.
