The six units were D&H 5000-5005, all ordered by the NYC and refused..they were built with NYC lightning stripes, rare for Alco hood units. they sat for a year or so until bought by the D&H.
All of the D&H high-hood RS11's were the NYC units..the rest of the D&H RS11's were low hood.
They were built as NYC 8009-8014
The story I read is that someone from the NYC placed the order with Alco, but the order was never "official" and NYC refused the units when they were completed..
(im sure someone else has more details than that!
Not many D&H RS11's were still running by the time CP came on the scene (early 90's) They last operated in 1993..(there was a story somewhere that one RS11 might have operated in 1994 on the D&H, but I dont know if that was proven or not.) basically 1993 was the end of the Alco era on the D&H.
At least one of the six NYC units still survived into 1994,
I caught 5002 in late '93.

Im not sure when 5002 was scrapped, but it was probably '94 or '95.
Only two D&H RS11's survive today, and neither is one of the NYC units.

I dont really think CP can be blamed for the demise of the D&H Alcos..their time was up anyway..all the C420's were gone around 1987-88, and only a few straggler RS11's and RS36's were still on the scene when CP took over the D&H..so IMO it wasnt so much CP that killed the D&H Alcos, it was just that their time was finally up.
