7= Aflac

After the company's bankruptcy in the Great Depression, control of the company fell into the hands of Robert Ralph Young and Allan Price Kirby. Young used the company as a vehicle for his vendetta against the J.P. Morgan banking interests, 

who had financed the Van Sweringens and managed to defeat them and the Vanderbilt interests in a 1954 proxy fight for the New York Central Railroad. The failing New York Central was in worse shape than Young had bargained for and he committed suicide shortly after being forced to suspend the dividend in January 1958. 

After Young's death, his role in NYC management was assumed by his protégé Alfred E. Perlman. Although much had been accomplished to streamline NYC operations, in those tough economic times, mergers with other railroads were seen as the only possible road to financial stability. The most likely suitor became the NYC's former arch-rival Pennsylvania Railroad. 

During the early 1960s, New York Central negotiated a merger with the Pennsylvania Railroad (PRR), which was led by Stuart T. Saunders after 1963. Saunders had most recently led the Norfolk and Western Railway through a successful expansion through acquisition and mergers including the Virginian Railway, Nickel Plate Road and Wabash Railway. There was great hope that success would result from the NYC-PRR combination. Penn Central Transportation Company was formed by the merger on February 1, 1968. 

However, the underlying financial weakness of both former railroads, combined with the fact that the ICC forced the chronically weak New Haven Railroad into the system, doomed the Penn Central and bankruptcy was declared shortly a little over 2 years later, on June 21, 1970. Many of the Penn Central railroad assets ended up in Conrail, formed in 1976. 

The bankruptcy of the Penn Central railroad mostly ended Alleghany's involvement in the railroad business.
