Underneath the mainline and arrival/departure track in the yard, I used N scale cork under the track. This slight difference in elevation makes it easier to tell which track is which.
Track is laid per Chuck Hitchcock's method of using adhesive caulk.
I really like this method. Track goes down easily and can be taken up without damage.
After the track is down, I spray it horizontally with Modelmaster light earth. Then, I give it a very light spray of Modelmaster Sea Foam Gray down from the top to weather the ties. Some tracks are weathered more than others. Before spraying, I rub the rail tops with 3 in 1 oil to prevent the paint from sticking and rub it off immediately. I only work with a couple of feet at a time.
I like a variety of ballast and use different types to depict the function of the track. This makes it easier for new visiting operators to get use to the layout.
For the mainline and arrival/departure track in the yard, I use a pink granite that was used by the Santa Fe and C&NW railroads. It is available from Arizona Rock.
For the yard classification tracks, car shop and engine servicing facility, I came upon a formula using Woodland Scenic's ballast developed by John Hathaway of Colonial Camera and Hobbies on Orlando. The mixture is 2 parts light gray, 2 parts gray, 1 part buff, 1 part brown, 1 part cinders. All are fine grade. This ballast is not rock and requires a dosing of isopropyl alcohol before using diluted white glue with a drop of soap.
For industrial spurs, I have a strong preference for Smith and Son Ballast. I mix 5 parts of brown with 1 part dark brown cinders. These people make great ballast.
