Rushing up the single CSX main track on a clear blue cold morning the now daily run CSX Q242-11 (Lawrenceville, GA - Louisville, KY) with a pair of Armour Yellow big birds, but the lead motor was special. Wearing the blue banner UP 7964 is known as the 5,000th Gevo or the successful Evolution Locomotive Series build by General Electric. "Kinda funny if you ask me!" With the banner on the side of this motor only indicate that this is a huge stepping stone for GE for building the popular Gevo. First time I've ever seen this motor, as it blast by at the M.P. 133.0 on its way north up the historic CSX W&A Sub.
