Thanks for the info!
There's an old photo in "Connecticut Railroads" that shows a GE80 tonner lettered for the Housatonic... I believe it was very early on in their revival as a tourist RR (common carrier too?).
It is still being stored out of service.
Not that this matters or is overly relevant to your fantastic layout...
But I found an online advertisement for a GE 80 tonner and in the description it said "former Housatonic RR...". So I think the Housatonic got rid of the 80 tonner.
Will find out more info in the future... Looks like Son #1 is going to be the conductor/switchman on NX-13. Aced his ride along Sunday and provided his physical and drug test is OK (it should not be a problem) and the UP sends his certifications to the RR, he should be starting with them sometime late December, early Jan.
