Converted two 6465 2 dome tank cars and a flat car into this 4 dome tank car
Converted two 6357/6457-type cabooses into this center cupola caboose.
Converted two Lionel flat cars into this circus flat. A string of these is impressive.
Simply cut the "fish belly" off a 6462-type gondola to make the top gondola. Reminds me of the Post-war American Flyer gondola.
