The first engine, the "Augustus Schell", passed over the bridge on February 18, 1866. Passenger trains started using it on February 22. After the Maiden Lane Bridge was constructed a bit further south, the Hudson River Bridge was used mostly for freight trains and the few passenger trains that passed by Albany but did not need to stop there. The Maiden Lane Bridge was often referred to as the "South Bridge" and the Hudson River Bridge as the "North Bridge". In the winter of 1866, once travel patterns were set, Cornelius Vanderbilt, owner of the Hudson River Railroad, suddenly refused to allow any transfers from the New York Central. According to the documentary "The Men Who Built America" the motivation for this closure was retaliation against the owners of New York Central for negotiating a new contract in bad faith. The New York Central board gave in, and in 1867 Vanderbilt acquired the company, and in 1869 merged it with the Hudson River Railroad to form the New York Central and Hudson River Railroad. This gave the New York Central a majority of ownership in the company; in 1900 the New York Central leased the Boston and Albany.
