[The rapid economic development following the Civil War laid the groundwork for the modern U.S. industrial economy. By 1890, the USA leaped ahead of Britain for first place in manufacturing output.[56]An explosion of new discoveries and inventions took place, a process called the "Second Industrial Revolution." Railroads greatly expanded the mileage and built stronger tracks and bridges that handled heavier cars and locomotives, carrying far more goods and people at lower rates. Refrigeration railroad cars came into use. The telephone, phonograph, typewriter and electric light were invented. By the dawn of the 20th century, cars had begun to replace horse-drawn carriages.
