This is INSANE!
We have been away and I haven’t run a train in over a month and today was a nice day so I grabbed the leaf blower and started cleaning up the RR. The leaves blew away from the foundation of the main factory and I noticed a pile of sand in front of it. Odd. I looked closer and the sand was inside and covering windows all the way up to the second floor which is 13+ inches up. I took the building apart and carefully lifted the sand loaded section having no idea what I would find.
I was thinking it was ants or termites but there was no evidence. I have had mice and chipmunks build nests in a few buildings but again no evidence of that.
Something had brought the sand to this building and filled it up. It is like the movie “The Great Escape” when the POW’s were digging the tunnel and had to secret the dirt out into the main yard using pockets in their pants.
The question is, WHERE did all this sand come from? It filled a 5 gallon bucket, 1.5 times.
I thought there would be a gaping hole under the rotted plywood base but there wasn’t even a chipmunk sized tunnel or hole?
This is really weird. Now that the factory is up and washed out, it needs a new base and loading docks, maybe a fresh painting. Crazy.
The rest of the factory is in great shape. It was a good idea to add the plastic trim board as a foundation to avoid ground contact.
Has anyone ever seen anything like this? The building was packed with sand.
Now I’m worried that I’m going to fall into a sinkhole somewhere in the yard because that sand came from somewhere. 
I’m suspecting it was the Chipmunks.
