Update needed

edit

This page is out of date. The UP SD60Ms do have a physical modification which includes the addition of a radiator flare similar to an SD70M-T1. This is evident in pictures of the units. http://www.rrpicturearchives.net/showPicture.aspx?id=1991794 Also, EMD's designation for the UP units is SD59M-2. http://www.trains.com/trn/default.aspx?c=a&id=6587 66.213.199.210 (talk) 19:38, 2 June 2010 (UTC)Reply
