@GG1 4877 posted:For early Amtrak there are photos showing leased FP45s and F45s in consists with SDP40Fs. One of my favorite consists is a photo showing a Warbonnet FP45 leading an as delivered blue and yellow F45, followed by a SDP40F pulling the Southwest Limited. While it seems like a lot of HP, three units were common when ATSF was pulling the combined El Capitan / Super Chief.
Did some of the ATSF F45's have pass through steam lines?
