Great job Norm! Well done. I don't understand why it wasn't built correctly originally. Seems like a simple modification and most likely less costly.

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.
