Top Ten of 2018. Here's a look back at my Top 10 favorite shots from 2018. 10. The first steam engines I photographed in 2018 were the Tennessee Valley Railroad Museum's two Southern Railway steam locomotives, 2-8-0 630 and 2-8-2 4501. The locomotives were the stars of Lerro Productions' two-day charter. On the second day, the pair led a freight consist on the line to Summerville, GA, seen here climbing the grade up Missionary Ridge just south of Rossville, GA. Lookout Mountain can be seen in the distance on this cool March morning.
