HISTORY OF TRANSPORT

Transportation takes us where we want to go, and brings us nearly everything we eat, wear, and use in daily life. Day and night swift airlines speed passengers through the sky. Long trains roar across the countryside carrying passengers, mail and such products as food, livestock and coal. Automobiles, buses and huge trucks rumble along the streets and highways.

Developments in transportation have cut travel time greatly in the past 200 years. In 1800 it often took a businessman a month to travel by sailing ship from London to New York City. Today we can travel this distance by jet airliner in only a few hours. Modern transportation also makes it possible to travel in comfort. Many of today’s trains have soft, reclining seats. Air conditioning may keep the air clean and cool and dining cars serve tasty meals.

Transportation would not be possible without communication. It depends on communication just as communication depends on transportation. Automobiles and trucks could not travel on crowded streets and highways without street signs and traffic lights. Automatic block signals and other means of communication enable railroads to operate safely. Airplanes could not land and take off safely without radio, radar and other electronic communication devices.

Without transportation our modern society could not exist. We would have no meals, no coal and no oil. Besides we would have to spend most of our time raising food – and the food would be limited to the kinds that could grow in the climate and soil of our own neighborhoods.

Transportation also affects our lives in other ways. Transportation can speed a doctor to the side of a sick person. It can take policemen to the scene of a crime within moments of being notified. In times of disaster, transportation can rush aid to persons in areas stricken by floods, famines and earthquakes.
