Warren Buffett’s company has sold two short-line railroads it recently discovered it owned to satisfy regulators who might have reviewed Berkshire Hathaway’s 2010 acquisition of the Burlington Northern Santa Fe railroad.

Berkshire told the Transportation Department’s Surface Transportation Board earlier this month that it had completed the sale of both short-line railroads ahead of schedule.

One of the two lines sold was the 12-mile-long WCTU railroad that serves an industrial park near Medford.
