I would not have laid so much track!
At least I started. And as with so many things, doing something new means learning how to do it. I've used Woodland Scenics flocking material before, but not in a challenging setting like railroad track. First you've got to get the glue on the sides of the roadbed, they apply ballast, the apply ballast between the rails. Then smooth it all out. Then apply a wetting agent and then apply the glue. You do this for about one or two feet of track.
Then you get to start over.
I'll add some pictures of the finished ballasting. I'm sure it will look good when finished.
By the time I'm done, I should be a real ballasting expert.
