D&H RS11 Question

Some questions regarding the following engine.

Why did New York Central refuse delivery of the high nose RS-11s that were
eventually sold to D&H?

When were these units retired by CP Rail?

Anyone know where they were cut up?

I don’t know why the NYC refused the RS11s. D&H took delivery in the first half of 1961. All units are reported scrapped, between 1988 and 1993.
