Always nice to find a "Dark Future" unit make its way into Colorado. A CSX CM44AC (rebuilt from an AC4400CW) leads an eastbound BNSF unit oil train on the main at Plain. The train is slowing to a stop as it will be meeting the westbound Zephyr here. Email Questions or Comments to the Webmaster. User Comments (0) No comments posted yet.
