Notes:  
A

UPY 2004 was built at Alstom Calgary in 2004 and sold to the UP in 2005. The core unit was former SOO Line GP9 SOO 4001. UP’s class for this unit is GG20GP as it uses an EMD GP unit as a core. From Don Strack’s UP Roster page (http://utahrails.net/all-time/upy-03.php#gg20gp-upy2000)

SOO 4001 was built in 2-1958 as MILW 2370, builder #23549, frame# 5545-3. The unit was later converted to use as a fuel tender by the SOO line, looking basically like a chopped down Geep with no cab. It was retired by CP and stored in Calgary before the hulk was sold to RailPower. SOO history from the Railroad Picture Archives Soo Photographic Roster (http://www.rrpicturearchives.net/locoPicture.aspx?id=10419) with additional comments by Trainorders.com user greendot.
