More coal pile holes: in 1946-47, American Flyer used a smoke and choo-choo unit in the tender. There was a hole for the smoke fluid filler. In 1971, when Lionel MPC introduced the electronic Mighty Sound of Steam, they thinned the coal pile above the speaker. Where the coal level was low, there were openings. This looked like shit, and weakened the coal pile. Lionel only did this one year. They figured out that they didn't need air holes, for sound transmission.
