Transferring more freight from roads to the green rail network cuts CO2 emissions and protects the environment. DB's new transshipment terminal, MegaHub Lehrte, shows how this works. Following completion, this fast transshipment base can handle up to 269,000 load units annually when operating at full capacity. This is equivalent to 20 large container ships' cargos. Modern technology in the form of a fully automated sorting system ensures this work is done with minimum noise and maximum energy efficiency.
Incoming freight trains' loads are regrouped according to the goods' destination stations. Containers and other freight carriers are transferred from trucks to trains. Twelve autonomous, fully electric transporters ferry freight from A to B at the site. These AGVs (automated guided vehicles) bring the freight to the designated cars. This means we avoid unnecessary crane usage, and it completely does away with the work of shunting trains. It also generates significantly less noise and CO2, while letting us eliminate up to 384,000 truck trips every year.
Three semi-automated gantry cranes, each some 20 meters high, take care of loading and unloading. They hoist the load units, some of which weigh up to 40 metric tons, and move them between freight trains, or between trains and trucks. The cranes are particularly energy efficient: They capture unused brake energy and feed it back into the electricity system so it can be used elsewhere. The site's IT also calculates the most efficient movements for the cranes and the AGVs.
The MegaHub's Lehrte use of modern technology makes it possible to reduce unnecessary maneuvering, thereby cutting noise pollution and harmful emissions when compared with other freight yards.
