In 1863, after years of development, the very first line in the London Underground went into service. Historically the New York Subway beats the Tube, as it would later became known, by almost 20 years. However, the New York Subway original configuration was to act as a long distance passenger trains and did not fully become a full subway system until the end of the 19th century. Because of this, the London Underground is recognized as the oldest, continually working subway system in the world.
