Yes the KATO Pooper (Super) Chief cars could be used with FP45"s but be aware by this time the Super Chief and the Hi Level ElL Cap trains were running combined as one train execpt occaisionally during busy holladay season when chair car and pullman trains ran seperately. No one has modeled the Budd Build Hi Level Cars in N execpt for expensive now hard to find Hallmark Brass models ,now kATO Amquack (trak) Superliner cars could be repainted and decaled to stand in as Santa Fe cars.
