Thanks JoeD for the compliments. The track was airbrushed with a mixture of Floquil enamels, RR Tie Brown, Rail Brown, Rust, and Grimy Black. I don't use a formula, I just mix it til the greenish tint from the Rail Brown is gone. The ballast gets a wash of diluted India Ink.
It's not a layout, just a 3' diorama I use for displaying cars. I've since removed the 3 rail track and replaced it with 2 rail track from Atlas. I do have 2 different layouts that I'm working on though. Their progress can be seen in the Layout Desing section here n the website, also I have a few YouTube Videos on my switching layout.
