Hhmmm.... here's an interesting thought... lots of folks here bemoaned Lionel for not re-issuing the S-3 will ALL the expected steam effects. And when somebody pushed hard enough to the folks at Lionel, he was reportedly told, "Wait 'till York".
This got me thinking... another locomotive catalog'd around the same time as the original S-3 was the Texas-Class 2-10-4 locomotive, which already is tooled for the cylinder-chest-steam feature. Lionel "just" needs to find space for another smoke unit to provide us with whistle-steam and any other desired steam effects.
So that's another steam locomotive possibility. It's a massive locomotive with lots of presence -- without being an articulated beast. But as I recall, the 2-10-4 will require O-72 curves, so that rules out a chunk of the market who has layouts with tighter curves. But what else is new? Lionel has been leaving behind the under-O-72 market for most of its VisionLine products anyway. And they haven't lost any sleep (or revenue) over it.
