Towards the end, the Northern Pacific had some beautiful boxcars. Surprisingly, there has not been many of their cars available from the high-quality manufacturers. My favorite scheme that I wish to highlight, is their pine tree green scheme.
It is really one of the classic boxcar schemes from the 1960s. Many of these cars survived well into the BN era.
I hope a company like Exactrail or Tangent takes notice of this glaring void.
