The ATSF and NYC PAs Lionel made in Michigan in 1997 use the same motors, but the tooling was modified to reduce a lot of the add on detail. I have and ABA set of the ATSF PAs from 1997 (two powered A units, Railsounds B unit). I'll eventually upgrade them with ERR Cruise Commanders but, as they sit with 4 of those big motors, they can pull like crazy.This engine will be worth the effort. It, along with the D,L,&W version were built by Samhongsa. Besides the bigger motors it has better detail than the PAs Lionel built a few years later. Maybe even better than the Legacy ones recently released but I have not seen those yet.
