Hello Adrian
Since you asked...
I could write a book about your statement here!
But I'll refrain...well

..., after all, maybe not!
It's just yet another reflection of today's situation!
The politicians here keep telling us we have a tight economy and competitive disadvantage with other countries but when you look at the numbers, we continue to have the second strongest PIB/ workhour in the largest 10 economies in the world.
And we have one of the best birth rates in the western hemisphere plus a health care system that's the world envy.
We have great food, no shortages, great wines, great cheese, great entertainers, excellent engineers and great scientists and a very skilled workforce and a rich and diverse culture.
Even a Belgian like me, living in France, can appreciate all that!
So much for all that good stuff ...but could a government ask for more taxes if they were not telling us continuously" it's tight" !
Imagine: "All is well, but we still want more of your money"
And they do everything to chase investors and businesses away...no wonder then, we, as a country, cannot curb the rising unemployment!
Of course they encouraged more births with all kinds of incentive (good!) ...without ensuring work would be there for them when they grow up (bad!)...
One year has never been a good horizon for long term planning..thank you past government for your great vision
As for the trains in question, I think it is a typical case of the left hand ignoring what the right does.
There use to have someting called a loading gauge....even **model**railroaders know that!
But now the SNCF (owns and runs the trains) has been severed from the infrastructure part (tracks, bridges, stations, )
Except for TGVs the SNCF hasn't bought new equipement for so long , that the people in charge are too young to have been exposed to the process of design validation (and probably never played with model trains, rather with video consoles where any crash is easily cured with the "restart" button) ...so this crucial step was left to the manufacturer to ensure.
That part was lost in the process there too....: when the customer asked for a "wider train" ...that's simply what they got!
Open loop control never worked...
My two €...and then some
Cheers
