The Williams FA/FB models are just so well done; Williams quality-of-accuracy is always
all over the place (likely to get better), but the Alcos pictured, among some others, just
seem to capture the engine's look even better than the fancier brands do. I spent a long time painting, weathering, detailing and upgrading a Williams A-B-A set for GM&O (must photo those). Both FA'a are powered/TMCC.
The GG1 is also a very nice model; a bargain. I have a PC version. It was well-priced a few
years ago at $275, and since then I have seen them go for $175, I believe. Almost
bought another one! But, there are only so many GG1's that a NYC fan needs. One.
