The current UP re-numberings
of former MP SD40-2 & GP38-2 units, and the modification of many SD40-2's
to 38-2s has caused the division of these original classes.
Just before Christmas 1999, a UP hump engine bearing the reporting marks
"UPY" rolled out of North Little Rock's paint shop, the first to bear
new road marks for low-horsepower units and part of a larger effort to
renumber morethan 3,000 locomotives.
The effort involves changing the road marks on CNW, DRGW, SP and SSW road
units to "UP," he said. All switcher-type units, plus hump engines andGP15s,
will be assigned "UPY" reporting marks. Most of these units also will
have new road numbers assigned.
The accelerated renumbering
is expected to take up to three years.
The National Motor Freight Traffic Association (NMFTA) granted UP a one-time,
special exemption for the new UPY reporting marks designation, tobe applied
to about 700 switchers, GP15s and SD38-2s. That, in turn, freesup 673
UP number slots for road units.
Information on the reporting marks and renumbering project will be made
available, probably on the UP Employee website.
As of 1994,
UP had retired the entire class of U30C's and a small number of the SD40's
were kept in storage, with the rest sold.
In total, 395 ex-MP
engines were painted into yellow & gray.
The last blue Missouri
Pacific engine (GP38-2, MP 2103) on the Union Pacific system was painted
in UP colors by August 1994 - though there is a slim possibility of units
sold to other rail lines that have eluded repainting.
The information in the above chart is subject to retirements, wrecks and
changes by UP.
