Union Pacific Greyhound SD70

During the Heritage Craze between 2006 and 2012 the Union Pacific Railroad created 6 eye catching SD70ACes painted in the liveries of their various Predecessors Railroads. However there WERE plans for a 7th unit painted in the famous Greyhound livery. Union Pacific SD70ACe No. 8444 carried the same nuber as the Living Legend, FEF-3 No. 844, had between the 1970s to 1989, and as such was considered a "Sister" to the 844. Because of this she was planned to be painted in the Greyhound Livery which 844 wore between 1989 to 1996. However things were chaged at the last minute and 8444 was painted in the Flag Livery that all UP Road Engines have carried.

This reskin attempts to recreate "What Could Have Been" by using Smokebox's FEF-3 DLC from Steam as well as adding a few new things like Headlight Flares from Searchlight Simualtions. This of course requires you to have the Union Paciifc FEF-3 from Smokebox as well as Searchlight Simulation's EMD 16N-710G3C-II | Sound Ehancment Pack.


  • Compatable with the FEF-3
  • Searchlight Simulation Flares
  • Custom High Quality Decals
  • Driver and Non-Driver Versions
  • Auto-Number Compatable

Additional Comments

This reskin was inspired by a similar reskin that had been made for OpenRails though I amnot sure it was ever released by the creator.
