From 2007:

>A May SEC filing revealed Berkshire owned 10.5 million shares of Union Pacific unp and nearly 6.4 million shares of Norfolk Southern nsc.

>Berkshire omitted those investments from a quarterly summary of its stock holdings filed earlier this month because the SEC allowed the company to keep them confidential, so it's not clear how much Union Pacific and Norfolk Southern stock Berkshire currently owns.
