Established as Manila Electric Railroad and Light Company to provide electric light and power and an electric street railway system to Manila and its suburbs. The facilities that Meralco built to provide these two services represented for many years the largest single investment of American private capital and know-how in the whole of East Asia.
For a little more than four decades, Meralco provided Manileños their first modern mass public transportation system with electric streetcars. These were supplemented by buses in the 20s.
