One of my grandfathers was a signal maintainer for the "Delay & Hesitate". He worked out of the yard between Alplaus & Schenectaday proper. His wife worked in the ALCO plant just across the Mohawk River in their business office.
I've always enjoyed the D&H and it's paint scheme; used to watch the freights enter the yard on the way into town from Mechanicsville.
Here's some shots of my Lionel U30C (which is for sale..). I also have an Atlas"O" Century series C628 in D&H livery
