CN drops bid and ends takeover battle for U.S. railway Kansas City Southern

Canadian National Railway Co. is dropping its takeover offer for Kansas City Southern, ending its takeover battle for the U.S. railway.

The decision comes after KCS on Sunday ruled a rival bid by from Canadian Pacific Railway Ltd. was a superior proposal to its deal with CN.

CN was dealt a setback last month when the U.S. Surface Transportation Board denied the company's use of a voting trust for the bid, saying it would be bad for competition.

The trust would have allowed KCS shareholders to be paid before the U.S. regulator completed its review of the proposed takeover.

CP, which is smaller and has a more limited presence in the U.S., already has approval for a voting trust.
