Sweden installs section of electrified road

Forget solar panels on the road surface – this is a different idea. Power is picked up by vehicles on the move, similar to slot cars. The report says: ‘They have also taken measures to ensure the rail is functional during inclement weather.’ Trialling in Sweden should put that to the test.

A team making up the eRoadArlanda project has announced that they have electrified a section of road near Stockholm, which will be tested by a battery-powered test truck.

The team is part of an initiative set up by the Swedish government’s Transport Administration to meet its goal of carbon neutrality by 2050, reports TechXplore.

The Swedish government has been funding projects aimed at developing a fossil-free road transport system for many years. In this new effort, the focus was on implementing a road technology that could be used by currently available vehicles. The result is what some have called a human-sized slot car system.

Slot cars are toy-sized cars that run on a track that also provides power via a metal drop-down rod on the undercarriage that slips into an electrified slot in the track. In the Swedish road project, the test truck has a similar drop-down arm that slips into a slot in the road and touches an electrified element that carries power to an onboard battery.

For the project, the researchers installed an electrified slot along two kilometers of road between the Rosersberg logistics site near Stockholm and the Arlanda Cargo Terminal. While other vehicles will be able to use the road, only a test truck will make use of the electrified rail.

In announcing the deployment of the rail, team members also reported that the cost of laying it was approximately €1m per kilometer, which they claim is 50 times lower than installing a tram line.

    Yeah, what happens when a car has a flat and the frame engages the hot rails? Or leakage trails develop between the rails? How to maintain traction in snow without spitznesparken of the snow plows? Or human traffic during mishaps?

    And how does one get on and off, engage/disengage the rail members without incident?

    They say ‘the rail only offers power when there is a vehicle present to draw power from it.’

  3. What happens when you go too fast round a bend? In Scalextric, a human hand picks you up and puts your thingy back in the slot!

    I bet the track or the bit that connects to it wears out very quickly. Trams and trains are constrained by their rails. Even Scalextric cars shot off the track on corners and the spigot holding it on often broke if it was used for any length.

    Low maintenance?

    Test device…

    Is it all a bit pointless?

    Back to the future

    You have got to go a long way to find a government as stupid as the swede’s

  9. Back to the ‘ole trolley bus which suffered all the problems noted above!

    Work OK in a sandstorm?

    Not many sandstorms in Sweden 😎
