Just looking at two of the major railroads in the United States... the BNSF (Burlington Northern & Santa Fe) is largely controlled by Warren Buffett (1/3 ownership), and the Canadian National Railroad's most significant owners are Bill and Melinda Gates (1/6 ownership).
I'm sure the geneology folks will do the research and determine Melinda Gates and Pres. Biden are 4th cousins once removed, but they definitely aren't close family.
