Well, almost free. There is a little effort involved.
Go to this site to download your free intermodal containers for HO and N scale.

If you have a problem downloading them I have PD F’s that you can print out on your printer. Cut them out and assemble with white glue. They look fantastic.
If you want these, Email me at wimberly3@hotmail.com with a request or come to my forum and post your request in the guest posting area. I’ll Email them to you as soon as possible.
**AUTHOR EDIT:**The containers don’t always print to scale on US printers. Set your paper size to A4. They will print to scale then.
