Morgan-oriented Seaboard Airline Railway?

I’m hoping there is someone here more familiar with this topic that could help me reconcile what, at first glance, seems to be conflicting data.

In Money in Crisis: The Federal Reserve, the Economy, and Monetary Reform Chapter 4, Rothbard writes:

However in Seaboard Air Line Railway: steam boats, locomotives, and history, Richard E. Prince indicates that Williams & the Seaboard “ran into stiff competition” with Morgan owned railways. (pg 86)

This article does show a closer connection to Morgan, but I’m not sure if it goes far enough to substantiate Rothbard’s claim that Williams and the Seaboard were “Morgan-oriented”, especailly since Morgan and Perkins seemed unwilling to deal with Williams unless Morgan could exert control of the companies.
