Load Test Car -- 1 car
- Length, Over Coupler Pulling Faces: 57'-11"
- Maximum Gross Weight: 220,000 pounds (110 tons)
- Load Limit: 156,800 pounds (78 tons)
- Built in 1994 by Motive Power International at Boise, Idaho, to accompany the LNG locomotives (UP 1298 and 1299) assigned to Los Angeles; moved to Council Bluffs when the two LNG locomotives were returned to MPI in 1998
- A special setup on a retired flat car to test the output of locomotives under full load. The electrical power from the locomotives was routed to the three sets of dynamic braking grids and converted to heat, which is dissipated by the rooftop fans. The two LNG locomotives did not have a self-test feature (like most if not all other modern locomotives). Most locomotives equipped with dynamic braking delivered after 1972 had their own self-test feature that used the locomotive's own dynamic braking to test the output of the locomotive.
- Sold by UP at auction at Denver Burnham, June 2010; sold to Arkansas & Missouir Railroad, seen in their Fort Smith, Arkansas, yard, in late October 2010.
