One of the places that I visited was the Meandre de Queuille – where the River Sioule makes an incredibly tight turn around a promontory of hard rock (yes, we ought to put a cafe on it – I know).

I’ve never been here before, even though it is something of a local tourist attraction that brings the crowds a-flocking. But maybe that’s the reason – having spent as long as I did working in the tourism industry my cynicism has made me immune to all this kind of thing.

That’s not the only thing that’s interesting about this place – at least, from my point of view. There’s also a dam – or barrage – across the Gorge de la Sioule just here and a very early hydro-electric generating plant.

Following the success of the hydro plant across the Sioule at the Viaduc des Fades, they built this one here in 1905. There’s a drop of 24 metres that powers 6 turbines that have an output of something like 20,000 volts and the power was supplied to the city of Clermont Ferrand.

I had set out originally to go to see these Health Assurance people. As I’m now a French businessman the health cover that I have is deemed insufficient. I’m required to take out a complementary assurance. But as luck would have it, the cover that I do have is recognised by the French government so I only needed to take out a top-up cover that makes up the difference between the total cost of any treatment and the amount that I would be reimbursed.

It isn’t cheap but in actual fact it is cheaper than the insurance I could take out in Belgium.

After that I hit the shops – Carrefour, LIDL and Bricomarche in Riom and the Auchan in Clermont Ferrand. And nothing of any real excitement except a USB fan for €3:00 – I’ll install that in Caliburn.

Outside the Bricomarche I saw the absolute ideal trailer. It’s 4 metres long, takes 2 tonnes in weight and has a double-axle with 13-inch wheels. It’s a bit knocked about but it’s not all that bad. It belongs to a company that is rebuilding part of the Bricomarche and the manager says that they haven’t used it in years. “So is it for sale then?” I asked optimistically. “Dunno” replied the manager “but I can find out”. So now that he has my phone numder we will have to wait and see.

But the most interesting part of the day was just outside Chatelguyon this morning. You’ve all heard of staff-and-ticket single line railway working. On single track railways there’s a danger that if two trains are heading towards each other they will have a collision. So what they do is to divide the line up into lengths with a signalman at each end and a passing place. These sections are called blocks.

Each block has its distinct staff – a brightly coloured stick – and no train can proceed into the block unless the signalman can give it the staff.  If he cant give it the staff, because it is with the signalman at the other end, the train has to wait in the passing place until a train coming the other way brings back the staff. With only one staff then of course there can only be one train in the block at any one time and hence the risk of collision is nil.

Of course it may be a while before the staff comes back to our signalman from the signalman at the other end of the block and if two trains are following each other this could be inconvenient. What our signalman would do then is to show the staff to the first driver who would then sign a movement book in the signalbox to say that he had seen the staff, and he would be given a ticket to proceed, which he would hand to the signalman at the other end of the block in lieu of the staff – effectively reminding the second signalman that the staff is still at the other end of the block and that another train is following.

And so today they were resurfacing the road in the hills outside Chatelguyon. The road was cut down to single-track and there were no traffic lights but a man was there stopping the traffic. There was a stream of cars coming the other way and the last car stopped and handed the workman a brightly-coloured object. Once that car had gone the workman waved us forward and showed us all the object – his authority to allow us to proceed and which he would presumably give to the last car in the queue to take to the other end.

I’ve never seen this done before on the public highway. I was impressed!
