The history of Orange & Brown IC trains in N Scale/ Gauge goes back to the Con Cor Limited Edition set in the brown box labeled "Panama Limited". Orange and Brown IC E-8-9 locomotives, since there were no correct smooth side Pullman's for this train Con Cor used coaches with sleeping car names applied. Fast forward a few years Con Cor began offering Open Stock cars and E Units in the IC Orange and Brown scheme with improved graphics on cars including the GN prototype dome coach which could pass for the former MP Budd dome coaches the IC acquired if you pained out some of the dome windows to represent the plating IC applied to those cars blanking some dome windows. Now we get to KATO , Their Orange and Brown IC sets are nicely decorated, but are generic at best the PS observation car is a close match to the two Panama Limited cars. "Stream Style Graphics" once offered decals for the distinctive lighted Panama Limited signs that were on the sides of the curved end of those cars, but by the time I went to order this decal set Stream Style was out of business. Various manufactures have done IC E Units , Life Like , Con Cor, Kato that I can think of. Passenger cars in the Orange and Brown scheme include Con Cor, KATO ,Walthers , now Rail Smith. If you want to model a real "City of New Orleans" model the Amtrak (Quack) Super Liner Train. Nate Goodman. (Nato). Salt Lake.
