It’s pretty fast, isn’t it? For centuries, humans have been trying to develop better methods of shipping cargo and people that are both fast and safe. We’ve been successful so far. But continuing to unlock the secrets of nature is a key to improving things even more. Railroads, in one form or another, have been around for thousands of years. The steam locomotives are still used in earliest type was probably some places. From Kingfishers to . . . Bullet trains speeding through History 5 the Diolkos pathways of ancient Greece. They were built and operated during the 6th century bce. Wagons were pulled along the Diolkos by either people or animals. The wagons’ wheels rolled through grooves that the Greeks made in the road. The grooves were not exactly the same as rails, but their purpose was similar. They were made to keep the wagons in place so they wouldn’t veer off course. In the 1500s, wooden rails were used in the European nation of Austria. Surprisingly, the earliest known line in that country is still in use today, although it has been upgraded with modern materials and equipment. Metal rails began to replace wooden ones in the 1700s. The wheels of a vehicle rolled better on a metal surface, and metal lasted longer and required fewer repairs. Around the same time, wheel design began to change. Most flange importantly, a was added to the wheel to keep the wheel on the track. By the start of the 19th century, the first steam- powered locomotive had been developed, and a steam-powered rail system was operating in England. It was so successful that similar railway networks were built in other parts of Europe. By this time, railroad cars were carrying both cargo and people, who were delighted with the opportunity to travel so quickly to faraway places. InnovatIons From nature 6 Asia and the Americas began to lay down their own tracks in the mid-1800s, and by the end of the century their systems were well established. Germany was the first nation to power its trains with electricity, in the 1880s. In the early 1900s, electrical power began to be used Diesel locomotives are used to pull both cargo and passenger trains. From Kingfishers to . . . Bullet trains speeding through History 7 the shinkansen line changed the way people travel in Japan. diesel in combination with fuel as a way of powering locomotives. By the middle of the 20th century, this technology had become common in many areas. In 1964, traveling by train entered a new era with the now-famous Shinkansen line in Japan. Its high-speed trains traveled at tremendous speeds, bringing people InnovatIons From nature 88 Learning & Innovation Skills to their destinations faster than ever before. The Shinkansen ran between the Japanese capital The oldest known method of Tokyo and one of its busiest of rail travel that still industrial centers, the city of exists today is probably Osaka. Today, the Shinkansen’s the Reisszug, in Austria. It is a funicular “bullet trains” can reach speeds railway, which means it is built on a slope. of 185 mph (300 kilometers per Cables positioned underneath pull the cars. hour). They carry more than 150 The cars are fixed in place—meaning they million passengers each year, run cannot be removed—and are operated by a solely on electricity, and have never pulley system. The Reisszug was first built had a passenger death because of in about 1500 and used to transport goods a crash or derailment. In addition, to and from Hohensalzburg Castle, situated the trains are environment- high atop a hill. Today, the line is powered friendly, emitting only 15 percent by electricity. Until 1910, people or horses of the carbon dioxide that’s powered the railway. released by an automobile on a similar journey. Other countries have used the ideas behind the Shinkansen to develop their own bullet trains. The popularity of bullet trains shows that they are the future of rail service around the world. But as with any human invention, bullet trains have had their share of problems. And when designers had to solve those problems, they found solutions in the most amazing place.
