Nice "Challenger" model there Ray
Got a mate with some lovely model of a Big Boy, and he's been keeping me up to date on the Big Boy they've just finished restoring in the US.
I found it amusing that after the restored Challenger was withdrawn from the tracks for overhaul and before the Big Boy was finished, the mantel for the largest steam locomotive in the world in use in preservation was the Australian Standard Garratt in New South Wales!
So I suppose it's now the 2nd largest until the Challenger is back!
Anyway, enough gunzelling...
Happy birthday Ray! And keep up the busy lifestyle, it does wonders for your health!
