The Plymouth diesel thread mentioned a 'Grey Granite Railroad' in Connecticut. The article below states #85 is now owned by someone else.

A Google search found this-excerpt below:

"Is that the James Brothers before their next train hesist?

No, it is actually the The Cavanna Brothers, John (L) and Andy (R), and the Cavanna Family of South Glastonbury .

They are are at it once again with the unveiling of the Grey Granite Railroad and their latest acquisition,
with the arrival of “Mack”, a 1928 Vulcan Iron Works steam locomotive. Mack is a 0-4-0 wheel arrangement tank engine that is fired by coal. Mack carries 1,500 gallons of water in his saddle tank, weighs 82,000 pounds, is 13 feet tall, and is 28 feet long. The engine was built in 1928 at Vulcan Iron Works in Wilkes Barre, Pennsylvania. The engine was then purchased by the Jeddo Coal Company, where it worked until it was retired in the early 50’s. Mack was later purchased by Gramling Locomotive Works, and underwent restoration from 2011 to 2017.".

The article that you linked to is from December 2019. Mack did visit that railroad but continued on to other railroads after that. I think Mack was just playing tourist as he does!

Agreed - I haven't heard any rumblings in other places about #85 being sold to anyone. Now, the Grey Granite folks did just acquire a different 0-4-0T from Canada for operational restoration, but that's a different story.
