Bracdude we don't know what you "mean" by your previous comment but if it relates to the use of junky old engines, that's a well-honed technique of ambitious and undercapitalized short line companies. If the management and crews work hard with what they got, they will be a tremendous improvement for their customers. Large organizations commonly struggle to pay sufficient attention to their smaller operations, so even if the Class 1s have talented employees, they'll likely never get attention in their capital budgets for improvement, or management attention to deal with NJ Transit potentially not honoring agreements for timely access to the Coast Line.
One short line that used junky old engines was a little operation call Genesee & Wyoming. Another is known as Delaware and Lackawanna. Both had quite the evolution.
I wish the Dover & Delaware team success in their expansion efforts.
