General Notes:

a. These are the first six-axle Genset units to be built; and were built using frames from retired UP SD40-2s.
b. Railpower's designation is RP20CD; UP uses RP20SD
c.

For unknown reasons, the builder data on the builder plates is in error, as shown in this comment from Jody Moore:

As verified by several independent plate checks, all four of them carry the same serial number of 1RPBDB20875000187 and build date of 12/07. That serial is not correct for any of them. Note that the sixth digit is B, not C. The serial number is also carried in its entirety on RPRX 5407, an RP20BD demonstrator which was produced around the same time. I'm fairly sure that it actually belongs to that unit, and that it isn't correct for any of the four RP20CD's. What's most interesting is that the decals that I've seen photos of actually have the correct unit number printed in the lower right hand corner for the unit that they've been applied to, and appear to have the correct original build dates for the cores used.

d. UPY 894 and UPY 895 were assembled for Railpower by American Motive Power at Danville, New York
e. UPY 894 was released in March 2009 and moved to Fort Worth, Texas, for its initial break-in period; moved to Roseville, California for regular service in May 2009, arriving on May 11, 2009.
f. UPY 895 was released on June 12, 2009 and moved to Houston, Texas, for its initial break-in period
g. UPY 896, 897, and 898 all have the same builder number. This has been checked and confirmed by three different individuals.
h. The previous reporting mark for UPY 897, 898, and 899 is WP, a temporary reporting mark used by UP for movement of retired units.

Notes:

1. UPY 896 was rebuilt using the former UP 4298 as its core unit; UP 4298 was purchased by Railpower in July 2007 and was stripped of all components by an outside contractor, then shipped to Canada Allied Diesel (CAD), Lachine, Que., for conversion to an RP20SD; UP later furnished UP 3291 to Railpower as credit for Railpower having purchased UP 4298; UPY 896 entered regular service at J. R. Davis Yard in Roseville, California, following a dedication ceremony on May 22, 2008.
