Forklifts can provide relief from noise and pollution. Several charging lanes are being built on test tracks – a first field trial is expected to begin in early 2019.
The construction of the first German test track for electric carriages with overhead contact line in the Rhine-Main region is progressing rapidly: the approximately 230 masts for trucks with pantograph are already on the A5 motorway between Darmstadt and Frankfurt. The arrows for the lines of contact of the airline are missing only in the south. "We are completely on time," says Achim Reusswig, Hesse Transport Authority project coordinator. By the end of November, the facility should be operational for the five kilometer long test track.
The field test should begin in early 2019 and help to achieve the climate protection objectives of the Federal Republic. In Schleswig-Holstein and Baden-Württemberg it takes a little longer.
Relief from Noise and Pollution
Construction work on the A1 motorway in Schleswig-Holstein is planned for October 2018 until the end of May 2019. The signal from departure of the pilot track was officially abandoned. Between Reinfeld and the intersection of the Lübeck motorway, a catenary for heavy goods vehicles must be built on five kilometers per direction. A Reinfelder forwarder will then test the road with a hybrid truck
For the third test track in Baden-Württemberg, the Federal Highway B462 (Rastatt-Rottweil), however, is still planning. The route should be about six kilometers long in both directions. The construction contracts will be awarded this year and the airlines will then be set up in 2019, says the state government. Each year, more than 500,000 tons of paper and cardboard are transported along the road. As part of the "eWayBW" project, airlifters would cover 250,000 kilometers per year with this load, so that managers expect reliable results.
The test track has two other benefits: Residents routinely complain about the sound of trucks. When using electric trucks, noise and pollution could be well studied. A comparison with the freight traffic would be possible because the section is parallel to a railway line.
The automaker Daimler wants to participate in its own way to the project and, by 2020, develop a purely electric propulsion tractor with a range of up to 200 kilometers. She should then start the comparison with trolleybuses.
Field Experiments with Financing
The Federal Ministry of the Environment is funding the three field trials by 2019 with a total of 45.3 million euros. The project in Schleswig-Holstein will again be increased by 5.1 million euros and will co-finance the test operation on all sites from 2019, said a ministry spokesman in Berlin. Trolleybuses have already been tested for several years on a non-public test track.
On the A5 between the Langen / Mörfelden and Weiterstadt crossroads the first trucks with electricity from 2019 airlines to drive. The field test begins with an introductory phase, which will take place around the middle of the year, said Siemens spokesman Stefan Wagner. Siemens builds the test track. In the introductory phase, the company's management should first be tested and carriers and drivers become familiar with the so-called hybrid hybrid truck technology. "Several vehicles are already used on the track in this phase." From mid-2019, the actual operation of freight forwarders with five vehicles should then be tested.
The system allows the use of different concepts of drive, purely electric, hybrid with diesel, biodiesel, gas, batteries or fuel cells, examples listed by Wagner. For example, vehicles can charge their batteries while driving.

Charging the batteries while driving
The trucks detect the cables on their sensors while they drive and dock without slowing Reusswig explains the factory "Elisa" on the A5 in Hesse. The pantograph is extended and coupled by pressure from below to the line. "He does not have to put on." Trucks can also change lanes by driving and detaching themselves, Wagner said. Because the system only works on the right of four lanes.
Until the trucks come after recharging their battery is still unclear, Reusswig said. This should show the test in the field and also depends on the weight of the vehicles. The infrastructure on the A5 leaves all kinds of trucks and maybe even buses.
"The technology itself works, yes," says Martin Bulheller of the Federal Freight Association. Now it has to be tested under real-life conditions, that it works, if not one, but 10, 20 or 30 trucks a day for months on the E roads.
