Trains and their transformation during the centuries Trains, one of the most important inventions by man during the last two centuries, reflect the developing -of our society: from the steam engine to electrical installations, this mean of transport could become ever faster and ecological. We can consider the steam locomotive as train’s ancestor. In fact, the invention of the steam during the first Industrial Revolution, led to the speed of working time in coalmines as well as the growth of international commerce. By time, train have started to become popular, especially after 1879, when Werner von Siemens, over the course of Berlin Exhibit, presented the first electrical locomotive – the same blueprint as our trains -. Consequently, thanks to the creation of technology and tertiary sector as well as the development of tracks, trains have been perfected. Nowadays, they represent the second mean of transports used by Italians after the car, and the most environmentally friendly. In my opinion, since trains are very green, there will have being a surge of their use by next 20 years. Furthermore, they could work by solar energy, as they are always exposed to sunlight – on the contrary to underground- . In conclusion, trains have seen a significant transformation since their birth. At the present, they are increasingly enhanced and will help to save our planet.
