Event Summary (Item 8.01 - Other Events)

This Form 8-K filing details Norfolk Southern's response to legal challenges concerning its previously announced merger with Union Pacific Corporation.

The company maintains that the original disclosures were adequate and that this action is to moot the claims and prevent nuisance.
