What I find a personal frustration, and falls into the "small steam does not sell" mantra is that I cannot get a 3-rd Rail "small steam" engine manufactured as recently as 2013.
"I want" the Sunset 3-rd Rail CP D-10 "Early" 4-6-0. Managed to get the "Late" version. It really hasn't been such a long time since 2013. Seems like yesterday to me!
However, in 2013 I was not back in this hobby. I had no opportunity to order.
And now, already, it's "unobtanium!"
