Conrail sold out at the end of December 1992. Danbury yard and the Maybrook east of the CT/NY state line was transferred to the Housatonic RR, but they never actually used the yard (and it eventually was transformed into the Danbury RR museum). The NY portion was acquired by Metro-North, and they never used it, either, other than for occasional (and rare) equipment moves.
The last trip I had out of Danbury was October 19, 1990, train WADA-1 to Wassaic, over to Dykemans and then up the Harlem line.
In my comment log for that day, I entered:
"First time I'd been to Wassaic since 1985 - and the LAST trip I'll ever make before they abandon the line."
And... it was.
