In 1877, the municipal government being, in its personnel, at the moment, incompetent to preserve the fundamental principles on which it was established, permitted a strike of railroad employees to grow without restriction as to the observance of law and order until it became an insurrection. Four million dollars' worth of property was destroyed by riot and incendiarism in a few hours. When at last outraged authority was properly shifted from the supine city chieftains to the indomitable State itself, it became necessary, before order could be restored, for troops to fire, with a sacrifice of human life. For some months preceding the riots at Pittsburgh disturbances among the railroad employees, especially the engineers and brakemen of freight-trains, had been frequent on railroads west and east of this city. These disturbances arose mainly from resistance to reductions in the rates of wages, made or proposed by the executive officers of the various railroads, and also from objections of train crews to regulations governing the transportation system. The Pennsylvania Railroad Company, some time after the panic of 1873, reduced the wages of its employees ten per cent., and, on account of the general decline in business, made another reduction of ten per cent. to take effect on June 1, 1877; these reductions to apply to all employees from the president of the company down. The reductions affected the roads known as the Pennsylvania Lines west of Pittsburgh, as well as the Pennsylvania Railroad, and similar alterations were also made on the New York Central and the Baltimore & Ohio Railroads. The changed conditions caused a great deal of dissatisfaction among the trainmen, but a committee was appointed by them, which held a conference with Mr. Thomas A. Scott, President of the Pennsylvania Railroad Company, and agreed to the reduction, reporting its conclusions to the trainmen.
