Back in the day Lionel seemed to avoid the 4 chuff actuation even though their sounds always had a very nice full exhaust sequence with speed sensitive cutoff effects. If you listen closely to a lot of older RS4 sounds you can hear the cutoff shorten at speed.
The first TMCC engine I can recall with a proper cam-actuated 4 chuffs was the USRA 0-8-0 switcher.

Correct on all points, Norm. We were hesitant about making a wholesale jump to four-chuffs, as the sound could become a "machine gun" at typical toy train speeds.

Nice to see everyone breathing new life into early 2000's Lionel!
