This Hemmingway trailer is just a toy, but it has been weighted to ride on the rail car. It makes a colorful freight company to add to the others on the train. While I have it off of the train, I think I'll do a bit more detailing before I glue it back on. I glue the trailers to the train cars with small drops of Elmers glue. It allows them to ride out the start/stops and bumps without vibrating off.
