Around here we used to have a junk day, toss out whatever and the town would pick it up.
We still have it, once a year you can schedule a pickup at your house.
I had a German Shepard who went everywhere with me, he took an interest in trains when I worked and ran them.
When I walked him he would stop at piles and sniff, if they had a train in them he would give me a little bark.
I guess from being around trains he sensed the odor of the train oil or smoke fluid?
I did go through those piles and picked out train items.
I guess when Grand dad passed folks didn't know what to do with his trains and toss them?
One pile we walked by the dog stopped and sniffed but didn't bark, he just looked at me.
I went thru the pile and pulled out a 101 Standard gauge bridge, complete with the box.
I will add the bridge at a later date, as I have to dig it out.
The box is not in great shape but for being maybe 100 years old it is a save of a piece of Lionel history.
These were offered from 1920 - 1931.
