American Railroad tracks. The model represents the old and abused rail system without maintenance. Long periods of time without any maintenance. One version has snow because I wanted to play with an ice shader. The lens flair at the time was the only way I was able to show off the light rust and wear damage to the top of the rail that otherwise is usually portrayed as just "shiny".
The wood ties were modeled in low poly for shape then a high poly was sculpted in Zbrush. The ballast track bed was sculpted in Zbrush to better define the rock effect as to not be flat.
