NS Southbound Freight Train 183 ( Birmingham to Mobile, Al. ) passing through 14th Street Interlocking in Birmingham, Al. The NS SD70 2574 at the time was the last SD70 left in the Conrail Quality scheme, about 3 months later 2574 was repainted into the NS Horsehead Scheme, luckily I was able to catch the 2574 leading on 2 different trains before the repainting
