Welcome to the forums
@Taizahn!
Take apart routes created by others that you like in Surveyor and poke around to see how they did things.
Create a small, single board route, and use that to experiment with. Many of us have what I've called A TEST ROUTE. Seriously, this is what I call it. I use this for experimenting with textures, looking at track or other objects prior to placing them on my own bigger routes.
Start small and work slowly. We all have big dreams of vast railroad empires. The problem is these vast railroad empires take time. If we set out these lofty goals with little experience, we end up getting overpowered, frustrated, and in the end the route ends up in the trash. By starting slow and expanding, the route can grow as you work on it and that leads to the next item.
When you finally are ready to try a "serious" route, establish a theme and a back history so that your route doesn't become an unwieldly monster. It can happen even if you have a theme, but what I'm getting at is it makes route building a lot easier if you give the railroad a purpose to exist.
When you become burned out, take a break. I watch cab ride videos and look at maps. These inspire me to get back on the saddle and continue to work on my routes some more.
Using this process, I've created a large, nearly 190-mile route, if not more, that was started in January 2004. I started by looking at other people's routes and then learned to use the tools. I used a theme I had from my once-built N-scale layout and expanded on that in the real world. The route is still in existence today and is slowly being renovated and updated. This brings up another thing.
Don't be afraid to throw stuff away or redo stuff over. Unlike a real model railroad, the only thing you are wasting is disk space, time, and pixels. You didn't spend $20 each for a turnout and who knows what for track, let alone the plaster, plywood, plastic, foam, and all the other goodies it takes to build a layout. Let it happen and it'll happen.
