The original LGB were awesome trains, loved their catalogs. They are still "good" today, but they have changed. What's worse is I haven't seen any new American offerings in YEARS. Mostly re-paints of old tooling. 2-6-0 Mogul, 2-4-4 or 0-4-4 Forney, Christmas Trolley, Grizzly Flats Chloe, F7s, Rail truck, Handcar, and the orig WP&Y diesel That's it
Piko G equipment is decent, but again offerings are VERY limited and not even close to scale.
Aristo is gone
The only players are USA Trains and MTH and Bachmann (limited items, all narrow gauge and a mix of 1:24 & 1:20)
