Iowa Interstate ES44AC 507 leads the RIBI ethanol train through Blue Island. I'm not a fan of the GEVOs but it is nice to see a engine on this end of the train instead of the caboose!
IAIS new GE ES44AC's 507 and 509 pass the only operating signal on the mainline and slows to take the switch at Yocum Connection to head to Cedar Rapids on the CIC line.
