UP 2300-2309 were funded by the Texas Emissions Reduction Program (TERP) and built at MPI Boise, ID using General Electric B23-7A core units. As such, they are classed by UP as GG20GE. From Don Strack’s UP Roster page (http://utahrails.net/all-time/upy-03.php#gg20gp-upy2000).

UP 2300-2309 are designated for use in the Houston and Dallas-Fort Worth area. From Union Pacific’s Low Emissions Projects page (http://www.uprr.com/she/emg/programs/paper09_05/emissions.shtml)

UPY 2300-2309 are the only Gen. II green goats built. They can be distinguished from earlier Gen. I green goats by the electrical cabinet. On the Gen. I units, it is slightly taller than the back of the hood. On the Gen. II units, it is not.

Unit moved to CAD Rail in Lachine, Quebec in late 2007 for upgrade work to Gen. IV standards. Released in mid-Jan. 2009 and moved by CP back to UP in Chicago.
