In late August 2016, a new caboose for Union Pacific appeared, painted in full UP yellow and gray paint and numbered as UP 26000. It carries class C-50-7. The new caboose is serving as a shoving platform on UP's LTS81 local in the vicinity of Eau Claire, Wisconsin. The local, known as the "Menard Job," works out of the former C&NW yard at Altoona, Wisconsin, and serves the large warehouse facility of the Menards home improvement chain, located in the northwestern part of Eau Claire.
UP 26000 is a wide vision steel cupola caboose, built in August 1973 as Soo Line 101 (2nd), part of a group of 80 cabooses built in 1973 for Soo Line by International Car Company, numbered as Soo 66-145.
A detailed history, with dates, of the car is not available, but it is known that Soo 101 became CVRX 101 when it was donated to the Locomotive and Tower Preservation Fund, Ltd. The caboose was stored along with the group's other pieces of railroad equipment in the former C&NW roundhouse at Altoona, Wisconsin. Union Pacific demolished the Altoona roundhouse in June 2004, at which time the group was forced to disband and disperse its collection. The group used CVRX as its reporting mark, for Chippewa Valley Railroad, named for the Chippewa River that runs through Eau Claire.
In 2005, the CVRX 101 caboose was leased to the Wisconsin Northern Railroad which had started operations in November 2004, operating over former C&NW tracks between Norma and Cameron, Wisconsin. It was returned to the preservation group after not being used by WN for a year.
(Additional information after 2006 is not available.)
(No information is available concerning how the CVRX caboose came to be owned by UP. One source suggests that upon UP ownership, it was sent to Omaha to be painted, and was returned to Altoona for service.)
UPP 400 and 401
Two ex CRI&P cabooses were rebuilt as test and laboratory cars, and numbered as UP 400 and 401 in November 1987 (the formal reporting marks are UPP, for Union Pacific Passenger). UPP 400 was the former UP 24531 (ex CRI&P 17113), and UPP 401 was the former UP 24540 (ex CRI&P 17122). Both cars were equipped with rooftop air conditioners and had special test equipment installed inside. The two cars were painted as standard UP cabooses, but without any car class markings.
Within three years, both cars were no longer needed and the test equipment was removed. The cars remained stored and unused at Council Bluffs until they were moved to North Platte, where all remaining equipment was removed. Both cars now have had several seats installed and are used intermittently as shuttle cars to move train and yard crews during periods when winter storms force the closure of local highways.
Both cars remain painted as cabooses, with North Platte Service Unit lettering in place of the more standard Union Pacific lettering.
In November 2009, the former SP 4750, a C-50-9 caboose, appeared at Denver's North Yard, numbered as UPP 430. The car is assigned to "snow bus" service west of Denver to transport crews during snow storms. Previously, SP 4750 was stored at Cheyenne, Wyoming.
MP 7500 Series
Beginning in December 1994, several former Missouri Pacific compact body cabooses were rebuilt to serve as Roadway office cars. Numbered as MP 7500-7514, most of the the cars had their interiors rebuilt to include bench seating along the interior walls, and were painted in UP's standard Roadway green. The conversion work was done by Parsons Railway Shops, the privatized former MKT shops in Parsons, Kansas, and was still under way by October 1995, with nine cars having been completed. Upon completion, the cars were assigned to Roadway trains.
Reports indicate that nine of the 15 cars were actually completed by the time the program ended in about 1996, at about the same time as the UP merger with SP, and possibly because of it.
Three cars were seen in December 1999 at Pine Bluff, Arkansas, in work train service: MP 7504 (ex MP 13823); MP 7513 (ex MP 13913); and MP 7514 (ex MP 13074). Also in December 1999, MP 7505 was seen in work train service at Overton, Texas.
As late as May 2001, many of the cars were in local service in Tulsa, Oklahoma, and Fort Smith, Arkansas. MP 7508 and 7509 were stored at Cheyenne, Wyoming, still in their original MP red paint scheme until 7508 was assigned as a tool car for the Ohio crane working in Iowa. MP 7509 remains stored at Cheyenne, Wyoming.
MP 7512 was seen at Echo, Utah, on September 20, 2013.
