Travelling by train can be enjoyable. A passenger can simply sit back and allow the journey to unfold at their leisure. The sounds of the train wheels on the rails the subtle rocking of the train and the opportunity to engage with fellow passengers are an unforgettable experience. There are a myriad of trains around the globe each with its own unique and interesting features. Some trains are amongst the fastest in the world. For example the Maglev in Shanghai is Chinas fastest train -- it operates at a speed of 460 km/h. Other trains are known for their long-distance routes such as the Trans-Siberian Railway which is the longest train line in the world operating for thousands of kilometers. Other trains are famous for their decadence and comfort; many trains around the world will allow the traveler to really travel like a king with exquisite decorations and luxuries beyond comfort. Each train is special and unique for a reason be it speed length or luxury. Why does it run without passengers? In this article we will discuss an exceptional train. Perhaps you have noticed a train go by and as a joke or mathematical exercise have seen people try to count the number of coaches that it has. A freight train typically has more coaches than a passenger train has; although it can vary according to specific assignments a freight train typically has around 60 or upwards of 70 coaches. Now consider a train that is even longer than that - a train that extends for kilometers and seems almost endless. Not just any train this is the longest train in the world. How many engines coaches and wheels does it have? This is not an ordinary train; it is the longest train in the world. It travels long distances and carries very large loads displaying the great engineering capabilities present in rail transport today. The train is an accomplishment of design power and logistics. The BHP Iron Ore rail service in Australia is the longest train in the world. It is a freight train not a passenger train. The BHP Iron Ore train had its first run on June 21 2001. Its length from front to rear is 7.3 kilometers. The train has 8 locomotive engines and 682 wagons used primarily for iron ore transport. It has even been said that if we put 24 Eiffel Towers in line their total length would fit in the length of this train. The train weighs 100000 tonnes. The entire train runs on 5648 wheels. What is the world’s longest train and why is it so massive? This train runs in the Pilbara area of Australia which is 7300 meters long and carries more than 99000 tonnes of iron ore. The more interesting part is that it is not a conventional train that has a driver. But it is operated remotely using AI navigation and real-time data. Prior to the Australian BHP Iron Ore train the longest train was the Mount Newman Railway in South Africa. The most unbelievable feature of this train was that it was driven by a single locomotive pilot which was amazing. This trains most unbelievable feature was that it was operated by just one locomotive pilot which is just incredible. The longest train ever was 7.353 km (4.57 miles or 24123 ft 11.61 in) long and consisted of 682 ore cars pushed by 8 powerful diesel-electric locomotives. Assembled by BHP Iron Ore the train travelled 275 km (171 miles) from the companys Newman and Yandi mines to Port Hedland Western Australia on 21 June 2001 reads the official website of Guinness World Records.
