I changed avatar today. The picture shows three LNER A4 class locomotives.
The one (green livery) nearest is loco Dwight D. Eisenhower 60008 (ex LNER 4496) and will return to Green Bay WI soon.
The middle loco is Mallard (World Record holder of 126 mph**) blue LNER livery No. 4468 (60008)
The further one is Dominion of Canada LNER blue 4489 (60010) due to return to Quebec with DDE.
There are six of these locos preserved, three of them are runners. The two ex pats are not.
It has been great to see these locos on our shores and I was fortunate to get to see them in October last.

** I know some American locos, particularly those of the Milwaukee Road, ran at very high speeds (for steam locos) but those speeds were not, as far as I know recorded. but just part of the usual daily operations.
