UP 1212 is 41 years old, having been delivered to MKT in April 1984 as a GP39-2. UP rebuilt the unit and it is now designated as a GP39N. The two radiator fans are spaced a bit further apart that most GP39-2s. Probably an artifact of the rebuild. Email Questions or Comments to the Webmaster.

(And I agree with you regarding clean UP units). Posted By Connor Friedrichsen On Tuesday, June 3, 2025 At 1:51:18 AM (PT) UP's motors sure look good when they're clean! MKT's GP39-2 order was, as you noted, delivered in 1984. By this later point in four axle EMD production, these GP39-2s were built on the GP49 carbody which had the wider fan spacing and angled blower housing. [ Add Comment ]
