And to add insult to injury -- I wanted to find out more about that plate visible in the Facebook image, but don't 'do' Facebook. If there is a link to it at either museum, I can't find it through a Web search...

And the US Facebook site is "FRIENDS OF the National Railroad Museum," while the British one is an official NRM Facebook presence.

Isn't the Ike normally displayed at NRM with some of the cars from his personal train when he travelled in England during WW2? I thought I'd read that somewhere.
If that's the case, then yeah, the locomotive would be a pretty big part of that display.
