The SD70 began production in 1992. The Burlington Northern merger happened in 1970 - after that, there wasn't an SP&S or NP (or GN or CB&Q) - just Burlington Northern. So other than fools like me, maybe; why would anyone want a model of 25+ year old locomotive in the paint scheme of a 40+ year old "fallen flag"? What era does it belong to? What rolling stock goes with it?
Conrail had 24 SD70s road numbers CR2557 to CR2580 all were sold to NS and are still in service today. They were to be SD80s but NS executives changed the order and used their road numbers knowing they were taking over their 58 percent soon. All 24 were originally painted in big blue paint. Then painted black post sale but kept their road numbers
