TORONTO, June 29 (Reuters) - Canadian Pacific Railway Ltd named railroad veteran Hunter Harrison as chief executive on Friday, falling in line with the hand-picked choice of activist investor William Ackman, who touted Harrison as savior of the industry-laggard company.

Harrison, who earned legendary status by transforming Canadian National Railway and Illinois Central Railroad into two of the industry's most profitable and admired companies, had been widely expected to replace former CEO Fred Green.
