Norfolk Southern's stock bounced on Friday after the company's better-than-expected earnings impressed analysts.

Shares of the rail carrier closed up more than 10.5 percent, over $91 a share, after the transport company posted first-quarter earnings of $1.29 per share on revenues of $2.42 billion Thursday. That was higher than the 97 cents per share on $2.4 billion predicted by Thomson Reuters consensus estimates.
