Another solution looking for a problem.

Might be useful if we lived in a reality where humans didn't steal stuff and where all of the roofs and poor grade land was already full of panels and we had no where else to put them.

Will they come up with a train carriage that runs over them with a brush once in a whiel to keep them clean?

And the first time they run a tamper over it, then do a ballast-drop, then run a ballast-plough, followed by a ballast regulator, there may be enough recoverable panels for the indigenous pilferers to make a few bob...   chocolateteapot

Are they not going to get covered en excrement flushed from the 4.14 to Paddington. What about leaves on the line, surely these will just make matters worse and there wont be any easy means to clear leaves without damaging panels. Do the people who come up with solar roads and now railways actually get out at all or have any idea what goes on in the real world. javascript:void(0);

The article does say:

In terms of cleaning the modules, Buri says that while most of the cleaning is done by rain, the company also has a special “robot train”, which works with water pressure. “It’s super efficient,” says Buri, adding, “when required, we press the button, our robot train arrives and scans the network with a camera, and a water jet system with ecological product cleans the panels as required.”

Leaves and other debris cannot be unique to the UK so presumeably they have tested things  Smiley

Not sure how well it will work when there is a third rail though  Huh

Seriously though folks, this has got to win the most pathologically stupid idea of the year award. Is someone paying this fool to come up with half-baked plans, or are we having April 1st early?

I agree, totally stupid idea
I have used railways in Europe. The sleepers ate covered in oil and grease that falls off the bottom of the trains.
A bit of water spray is not not going to shift that easily.

I don't fancy being the track pv worker dealing with earth faults due to thee being a poo sodden wee soaked clod of loo roll on the panel.

I was hit by golden brown shower from a train exiting dawlish station when I was 16. Not good.
I now give all trains a wide berth .

The HSTs are now the only trains that empty directly onto the track. All modern stock has catch-tanks that are emptied every night at the depot. If the tank gets full, the bog is placed out of order.

What about heritage trains running Mk2 or 3 coaching stock, are they expected to be upgraded?

It was in July 1979. It was from an Hst.
I walk my dog by near to the railway between Crewe and Nantwich. It has mainly arrive trains dmu train sets  on it. Freight much reduced since the closure of iron bridge power station, bit still get ballast trains pulled by class 43s or nice clean class 66s. Saw tornado come through a few years back pulling 15 coaches , old type.

Lots of oil and grease on the concrete sleepers.
Power washing it would cause problems to the panels and more importantly to the signalling circuits.

The railways must have their equivilent of the plant modification procedure. Like on the nuclear power industry. Once its safety significance is established, it will be subject to higher degree of scrutiny in the design, execution and implementatation. Therefore probably get kicked out.

Heritage/steam specials services are still exempt, but the RTM is kicking up a fuss about the exemption every chance they get. Oddly for once, I am in agreement with the RTM on this issue. We may have a sh!t railway services most of the time, but I can't see a need for the sh!t to end up on the rail tracks.

I have watched the renewal of Reading station from start to finish, with the new flyover and the electrification. When first finished  it was  a bright, clean wonderful place to be. (or get lost, confused etc) What has spoiled it from then is 'sh!t'.
New rails, clean ballast, sh!t and toilet paper all along the 4-foot in full public view. clods of the stuff where people are used to containment toilets so don't bat an eyelid when they take their ease on alighting the train.
Platforms with beautifully laid flags, small and large geometrically wonderful, bright and clean.  Then the cleaners come along, dragging their sacks of rubbish: Coffee, soup, noodles etc all exuding fluids that drain from the sacks as they abrade their way along the platforms to the rubbish-collection area. The sack-draggers never take the same route, so a new trail of sticky brown mess is deposited every day.
The foot-bridge is a 30 metre wide concourse that enables the public to get from A to B without congestion (until they get to the escalators and lifts). Pigeons have now taken over; the hawk-man no longer patrols the bridge to scare them off. Passengers now face the course of slippery pigeon mess from above, on handrails, walls and every other surface. The flying rats now walk unchallenged amongst the public as they pass from train to train - they do not have the time to be concerned, they have a schedule to keep, we all do.
In rail traffic terms, the station is absolutely there. The people side of things is rapidly slipping into decay.
Grrr!
