If you have the hollow core door and want to make 2 @39 3/4 inch x 24 inch sections, it is easy if you do it before you put down track and scenery permanently. Just cut your door in half, and glue a 2x2 spacer into each open end. You might want to use some finishing nails or screws through the door into the 2x2 to ho9ld it for the glue to dry, but I don't think it is necessary if you let the doors sit for 24 hours to let the glue set up and cure completely.
