What is transportation?
Transportation means movement of people, animals, and goods from one location to another. Transportation sector employs around 16% of tourism workers
Tremendous growth potential;

Generates direct and indirect employment to millions across the globe;

Evolution of Transportation

Archaeologist believe that transportation started in either Mesopotamia or Asia between 4000-3500 BC by the invention of wheel
The next logical invention from wheel was chariot and cart. The first Chariot was found in Samaria.
Build around 3500 BC this invention increased the speed of travel over land and four wheeled chart was introduced
By this Development means of traveling through boat was started
By 1800 Ships began to shed their sails in rivers once again. The advent of transportation was changing transportation forever
In 1804, locomotives, which used steam to power a series of pistons (much like a steamship), came into use. These locomotives were powerful enough that one engine could pull several cars, a feat hopelessly beyond the capacity of the earlier steam engines.
Over the next century, various improvements would be made to the locomotive, speeding up transit and attempting to make train travel safer.
Then, during World War II, the diesel engine came into widespread use, instead of steam.
In 1895 Even electricity had been experimented with in the running of trains, but was considered too expensive and unreliable to run until the advent of the subway, when electricity became the easiest and cleanest means of underground motion.
The next stride in transportation looked not to the land, or even to the seas, but to the sky. Although many people have toyed with flight over the millennia, the first sustained, controlled flight didn't take place until December 17, 1903, at Kitty Hawk, North Carolina.
After centuries of rockets unable to pierce the atmosphere and escape the gravitational pull of the earth, on July 16, 1969, American astronaut Neil Armstrong became the first man to set foot on the moon.
From the wheel to the stars, man's travel has only ever been limited by the scope of his imagination.
An air transportation can be covered with airplane, helicopter etc. An airplane, is a heavier-than-air craft where movement of the air in relation to the wings is used to generate lift. The term is used to distinguish this from rotary-wing aircraft, where the movement of the lift surfaces relative to the air generates lift. A gyroplane is both fixed-wing and rotary-wing. Fixed-wing aircraft range from small trainers and recreational aircraft to large airliners and military cargo aircraft.
Two things necessary for aircraft are air flow over the wings for lift and an area for landing. The majority of aircraft also need an airport with the infrastructure to receive maintenance, restocking, refueling and for the loading and unloading of crew, cargo and passengers. While the vast majority of aircraft land and take off on land, some are capable of takeoff and landing on ice, snow and calm water.
Rail transport is where a train runs along a set of two parallel steel rails, known as a railway or railroad. The rails are anchored perpendicular to ties (or sleepers) of timber, concrete or steel, to maintain a consistent distance apart, or gauge. The rails and perpendicular beams are placed on a foundation made of concrete, or compressed earth and gravel in a bed of ballast. Alternative methods include monorail and maglev.
A train consists of one or more connected vehicles that operate on the rails. Propulsion is commonly provided by a locomotive that hauls a series of unpowered cars that can carry passengers or freight. The locomotive can be powered by steam, diesel or by electricity supplied by trackside systems.
In rail transportation two types of trains one is passenger trains and the other is goods trains.
