Up for auction is a series of placeable buildings and signs for O gauge model trains. Most of these were made by Lionel and are intended for O gauge, but I'm sure you could make them work in other scales as well. There's likely some Marx and Ives mixed in here too.
The big pieces are a long plastic elevated bridge, a sheet metal tunnel, and two girder bridges. Some of the streetlamps are also notable. Please take a look at the images & judge for yourself. I'll note, almost everything here is in poor or salvage condition. You'll want to do some restoration work on almost all of these pieces. They would also be good for parts if you already have similar components.
