Well, here is a wooden caboose I built in high school. I started out with balsa wood and then cut strips of 3x5 index cards to glue on one plank at a time over the balsa. Since I was going to run in on my Lionel layout behind a Berkshire steam engine, I needed Lionel trucks. I also needed couplers so I cut them out of 1/4" plexiglass. Several moves and years in storage have not been kind to this caboose. I found it today while looking for some parts stashed away in a box. Well those broken steps needed fixing and the trucks had to go.
