Train leaning from and forth

Although many travelers believe that the train is more comfortable than other modes of transport, it is sometimes impossible to nap. In fact, when there are many curves along the path, the body moves from side to side due to centrifugal force.

To solve this problem, engineers have used the latest technology to build a train that leans into curves. The new model is called Virgin’s Pendallino, recalling the movement of the pendulum. Before entering the curve, the wagons lean to one side and as they leave, to the other. Thus, the curve can take without slowing down and passengers do not perceive this movement. The Pendallino will travel more than 140 miles per hour, while today the high-speed train moves around 110 miles per hour.

On the 13th, the first tests will begin on a Leicestershire track. According to the expectations of the managers, in the middle of next year new trains will begin to be used on the main line of the west coast. Meanwhile, Railtrack staff are adapting different sections of the tracks so trains can catch these high speeds.

The train, however, will not work as fast at first. In the first three years the speed will be 125 miles per hour. At that speed you will arrive from London to Glasgow in 5 hours and 15 minutes. For the year 2005 the speed will be 140 miles per hour and the same tour will take place in 3 hours and 55 minutes.

The technology base used on the train was first tested in England 20 years ago. Then it was unsuccessful. The cars were not safe and the travelers complained of feeling bad. Now, however, according to Dr. Alan Wickins, who participated in the initial project, this problem is solved. At first, the wagons bowed heavily and the centrifugal force was completely neutralized, and that was the cause of discomfort. In view of this it was thought to build less inclined wagons. But the construction of the train was long and British Rail decided to abandon the project in the early 80's. At that time, similar trains were also being designed in Italy. There, however, they managed to carry out the project and the built cars continue on the train tracks.

However, not all high-speed trains should be tilted. When the curves are not very tight, it is not necessary to tilt the train from side to side. In France, for example, the railways are direct, and that makes the train very fast.
