suggestion-

Before laying any track, paint all the foam/exposed plywood/etc. a "mud" colored flat latex house  paint. Can be interior. Makes a world of difference while you're getting to the [point of landscaping. And adhesives will stick to it.

Rebuttal to suggestion

DHfan,

I laid the track on my N scale layout before painting the foam and didn’t mind painting around the roadbed. More specifically, I had pre-painted the roadbed and track areas before laying the track- which made the process easier.

But that’s not really the important thing here. The important thing is that by doing, we’re (hopefully) learning. My first layout as a teenager was an around-my-bedroom N scale layout that never grew past 2x8. I later ditched that effort to join an HO modular club where I started two 2x4 modules that I also never completed. Now, I’m back to N scale and have readjusted my goal to 2x4. Small, yes. But it’s the best I’ve done so far!

Thanks or the advice, I will

Thanks or the advice, I will keep that in mind when doing the other half of the layout! 

Great looking 70's era train.

   I like your video, looks like you are having lots of fun. Your track seems to run nice and smooth. I think it's smart to run trains before getting too far into scenery as you'll probably find things you want to change.  I'm adding three turnouts for a crossover and another yard track after running my layout for a while....DaveB
