This was the 60th anniversary event at IRM, in which they brought in Lehigh Valley Coal Company 126, Central Pacific Railroad 63 (The Leviathan), and UP 6936 (DD40AX). All the running locomoitves include the Leviathan, LV 126, The Nebraska Zephyr, BN 3, CSS&SB 803 (Little Joe), and several other trains. The DD40AX and the UP Gas Turbine were also on display, but 6936 ran during the night shoot. Here's a photo I took of the DD40AX and the Turbine: http://www.railpictures.net/photo/449694
