The "Railbuffs", members of a rail club affiliated with the University of Colorado in the US, regularly set off to spot special trains. Central to this series is the Union Pacific Laramie Sub in Wyoming. Among other things we see trains from Cheyenne to Granite on the Transcontinental Mainline, the Amtrak California Zephyr passes by due to a detour on a different route and near Denver we spot historic E Units pulling the Cheyenne Frontier Days Train ahead. Videos from 2015/2019.
