Athearn uses the same frame and weight for both a & b units that are powered and the same frame on all dummy units. I don't know about Highliners and Genesis units, but the Highliners were originally designed to retro fit to the old blue box f units, so I would expect them to fit. The new Genesis A units are also designed by Highliner, in fact you can buy the undecorated Highliner body kits directly from Highliner. Athearn only has an exclusive on the decorated bodies.
