At The Big E yesterday I spoke with Lionel Director of Production, Ryan Kunckle about the quality of sounds, and specifically "chuff" we'll be getting in the new LionChief Plus 2.0 engines in 2019. I was concerned that the current version of RailSounds contained in LionChief Plus locomotives, when applied to 4-chuffs per revolution, would sound like a machine gun.
According to Ryan, the RailSounds in the LionChief Plus 2.0 locomotives will be more more akin to the varying chuff we hear from the TMCC/Legacy levels of production. In other words, not just one chuff sound on a loop. I'm glad that these changes are happening, as these engines are as close to bullet-proof and as packed with play-value as anything in the Lionel line. And selfishly I might add: they run on O-31 curves and switches!
