Cell phone photo of a new MARC locomotive in Denver, CO, sent to me by Matt Faruolo of DenverSkyscrapers.com:

The locomotive is one of 26 MPXpress units that MARC ordered to replace aging 1970s-era GP40WH-2s. They are manufactured in Boise, ID and tested in Pueblo, CO (thus the Denver connection). The first few locomotives in the order should begin operating on MARC trains any day now, if they haven’t done so already.
