Lübeck / Kiel (dpa / lno) - Almost a year after the start of the E-Highway test route on Autobahn 1 between Reinfeld and Lübeck, Schleswig-Holstein's Transport Minister Bernd Buchholz (FDP) drew a positive interim balance.
The field test had shown in around 1000 rounds of the test vehicle that the route was suitable, said the minister of the German press agency.
"There are still a few small defects that need to be corrected, but by and large the project is going well."
On the five-kilometer test route, a hybrid truck from Reinfeld's Bode forwarding company commutes between Reinfeld and the port of Lübeck several times a day.
An overhead line supplies the vehicle with electricity.
The experiment financed by the Federal Environment Ministry is intended to show whether the overhead contact line technology is suitable for long-distance freight transport in Germany and how the technology affects the environment.
"It is still too early to make any statements," said Elisabeth Niehaus from the Research and Development Center at Kiel University of Applied Sciences, which is scientifically accompanying the project.
"The first data from the various measuring systems from the vehicle and on the system are available, but they have not yet been evaluated," said Niehaus.
So far, the forwarder has only been on the route with one hybrid truck, and another four vehicles are to be delivered by the end of March 2021.

The test track is one of three in Germany on which an overhead line system for the electrification of heavy commercial vehicles is to be tested.
A second test track is located on the A5 in Hesse, the third on the B462 near Rastatt in Baden-Württemberg is scheduled to go into operation in spring 2021.
"It is not about equipping all motorways in Germany with overhead lines," said Buchholz.
"But on routes like the A1, where heavy traffic is regularly on shorter routes, at least a test is advisable," he said.
