Need identification on this part

I was at Strasburg recently and I noticed this piece of metal. I was wondering what part it is? (Could it be a saddle tank?) And if anyone knew what locomotive it was from?

Yes, looks like a saddle tank

I would suspect it is from whichever of the BEDT engines that gave up it's identity to become Thomas-
