Commodore Vanderbilt

Vanderbilt Avenue adjacent to the East side of Grand Central Terminal is eerily quiet on Memorial Day.

The man who started all of this was Cornelius Vanderbilt...

Cornelius Vanderbilt versus Jim Fisk in a famous rivalry with the Erie Railroad

New York and Harlem Railroad

Though Vanderbilt had relinquished his presidency of the Stonington Railroad during the California gold rush, he took an interest in several railroads during the 1850s, serving on the boards of directors of the Erie Railway, the New Jersey Central, the New Haven and Hartford, and the New York and Harlem (popularly known as the Harlem). In 1863, Vanderbilt took control of the Harlem in a famous stockmarket corner, and was elected its president. He later explained that he wanted to show that he could take this railroad, which was generally considered worthless, and make it valuable. It had a key advantage: it was the only steam railroad to enter the center of Manhattan, running down 4th Avenue (later Park Avenue) to a station on 26th Street, where it connected with a horse-drawn streetcar line. From Manhattan it ran up to Chatham Four Corners, New York, where it had a connection to the railroads running east and west.^[17]

Vanderbilt brought his son William Henry Vanderbilt in as vice-president of the Harlem. William had had a nervous breakdown early in life, and his father had sent him to a farm on Staten Island. But he proved himself a good businessman, and eventually became the head of the Staten Island Railway. Though the Commodore had once scorned him, he was impressed by William's success, and eventually made him operational manager of all his railroad lines. In 1864, the Commodore sold his last ships, concentrating on railroads.^[18]

New York Central and Hudson River Railroad

Looking out the north end of the Murray Hill Tunnel towards the station in 1880; note the labels for the New York, Harlem and New York, and New Haven Railroads; the New York Central and Hudson River was off to the left. The two larger portals on the right allowed some horse-drawn trains to continue further downtown.

Statue at the modern Grand Central Terminal

Once in charge of the Harlem, Vanderbilt encountered conflicts with connecting lines. In each case, the strife ended in a battle that Vanderbilt won. He bought control of the Hudson River Railroad in 1864, the New York Central Railroad in 1867, and the Lake Shore and Michigan Southern Railway in 1869. He later bought the Canada Southern as well. In 1870, he consolidated two of his key lines into the New York Central and Hudson River Railroad, one of the first giant corporations in American history.^[19]

Grand Central Depot

Main article: Grand Central Terminal

In 1869, he directed the Harlem to begin construction of the Grand Central Depot on 42nd Street in Manhattan. It was finished in 1871, and served as his lines' terminus in New York. He sank the tracks on 4th Avenue in a cut that later became a tunnel, and 4th Avenue became Park Avenue. The depot was replaced by Grand Central Terminal in 1913.
