purpose of the Temple Iron Company was to lock-up independent coal production and control the supply. Congress reacted with the 1906 Hepburn Act, which among other things forbade railroads from owning the commodities that they transported. A long series of antitrust investigations and lawsuits resulted, culminating in a 1911 Supreme Court decision that forced the LVRR to divest itself of the coal companies it had held since 1868. The LVRR shareholders received shares of the now independent Lehigh Valley Coal Company, but the railroad no longer had management control of the production, contracts, and sales of its largest customer. In 1896 the very early film Black Diamond Express was produced by Thomas A. Edison's company Kinetoscope. The train arrives from far away and passes the camera, while workers are waving their handkerchiefs. 1900–1920 Fortunately, grain tonnage was increasing and the company transported large quantities from Buffalo to Philadelphia and other Eastern markets. Also, in 1914 the Panama Canal was completed, and the LVRR gained an important new market with ores shipped from South America to the Bethlehem Steel company. In order to handle the additional new ocean traffic, the LVRR created a large new pier at Constable Hook, which opened in 1915, and a new terminal at Claremont which opened in 1923. It also built a passenger terminal in Buffalo in 1915. Since 1896 the LVRR had run an important and prestigious express train named the "Black Diamond" which carried passengers to the Finger Lakes and Buffalo. Additional passenger trains ran from Philadelphia to Scranton and westward. From the beginning, the LVRR's New York City passengers had used the Pennsylvania Railroad's terminal and ferry at Jersey City, but in 1913 the PRR terminated that agreement, so the LVRR contracted with the CNJ for use of its terminal and ferry, which was expanded to handle the increased number of passengers. The railroad also published a monthly magazine promoting travel on the train called the "Black Diamond Express Monthly". In the war years 1914 to 1918, the Lehigh handled war materials and explosives at its Black Tom island facility, which had been obtained along with the National Docks Railroad in 1900. In 1916, a horrendous explosion occurred at the facility, destroying ships and buildings, and breaking windows in Manhattan. At first the incident was considered an accident; a long investigation eventually concluded that the explosion was an act of German sabotage, for
