Who doesn’t appreciate the ALCO PA dressed in Santa Fe’s warbonnet livery? Much research goes into replicating my mail trains. From power assignments and consists, check out this well done web address, It is a valuable source of information along with articles by the Santa Fe Railway Historical Society and other various publications. The ALCOs were manufactured by Like Proto 2000 20 plus years ago. I was able to cosmetically work around the factory paint as I added details. Challenging? Yes, but worth it. The PAs have Tsunami 2 decoders and Soundtraxx Sound Car decoder in the combine.
