On the N Scale Suppy website: ( www.nscalesupply.com/ ) on their "Pre-Owned" page, there's an N scale Atlas B30-7 in the Mandarin red and white scheme for sale $50. Also a Frisco hopper car. FYI. Tom
Even though I'm an HO guy I went and check it out. If you search for the road name Frisco you will find a B30-7, a U25B, a GP38, a 2 bay hopper and a passenger car. If you search St. Louis - San fransisco you will find a box car.
