\"AerialThe transport sector in Europe accounts for around 20% of the Co 2<\/sub> Responsible for emissions and thus one of the main causes of Co 2<\/sub> Emissions. That is why a shift in freight transport to rail is the order of the day. And at the moment one has the impression that due to the global climate crisis Movement in rail freight transport<\/a> comes. One of the important milestones in rail freight transport would be a digital automatic coupling (DAK). A simpler automatic coupling has been implemented in North American rail freight transport for decades.<\/p>\n

What does the automatic coupling do?<\/h3>\n

With the automatic, freight wagons are automatically connected to electricity, data and compressed air lines. This makes coupling faster and easier. Because domes are hardest manual work. For more than 100 years, wagons have been linked with heavy screw couplings. This process takes a long time, is hard work and can be very dangerous. Serious accidents happen again and again during this work. When coupling, the employee has to hang the heavy screw coupling between the wagons, tighten the connection and connect the brake lines by hand. In addition, this work often takes place at night. Railway companies also complain that they cannot find employees for the job.<\/p>\n

How does the digital automatic coupling (DAK) work?<\/h3>\n

\"Close-upThere are different types of coupling. The DAK type 4 is to be used in Europe. This model combines an automatic coupling with the digitization of the freight railways.<\/p>\n

When coupling, brake lines and additional power and data lines are automatically connected. This should then make it possible to install and use sensors on the individual cars that communicate with the towing vehicle.<\/p>\n

Dangers of the current system<\/h3>\n

It is currently the case that the train driver in the towing vehicle has no idea what is going on with the attached freight wagons. It sometimes happens that a wagon of a train derails and the engine driver sometimes only notices after 1,000 meters that something is wrong. By then, the derailed wagon could have caused several million euros in damage to the infrastructure. There is simply no communication between the wagon and the locomotive, and the large mass of the train does not immediately make the derailment of individual wagons obvious. If the train had installed sensors that would indicate such a derailment, major damage could be prevented. The DAK would have already integrated such systems.<\/p>\n

Advantages of the digital automatic coupling<\/h3>\n

The digital automatic coupling has many advantages:<\/p>\n
