That is correct. A few years ago UP needed a new numbering system to have more blocks of numbers because they were almost at capacity with 4 digit numbers and 5 digit numbers were too big of a hassel with computer systems. Thus, UPY was created. Yard locomotives (swithers, smaller odd locos (i.e. GP15's) etc.) were placed in this new system freeing up larger number blocks for newer road power.
