There used to be a station at the bottom of the Eiffel Tower.
Huge: 20 tracks, 10 platforms, able of accommodating thousands of passengers.
And this is not a fake.
Thread History⤵️
The adventure began in 1867.
The city of Paris is organizing its first Universal Exhibition.
On the current "Champs de Mars".
At the time no Eiffel Tower, that will come later.
It lasts 7 months and 6.8 million visitors will flock there to see the latest inventions from all over the world.
But at the time, transportation was roughly limited to 3 things.
Walking, horse and train.
And almost 7 million visitors, that makes many horses.
So there was a need for a train, and therefore a railway line.
The train is good, it can carry a lot of people all at once.
Today we call it "Mass Transit". We didn't invent anything.
We are therefore going to build a station (a small one to start with 4 tracks at the platform), near the exhibition.
To do this, we are going to divert a railway line from Grenelle station on the "Small Belt" (
a circular line that goes around Paris), to "Champs de Mars".
It is seen here in this drawing from the period.
This is destroyed at the end of the exhibition.
End of the story? Not really.
In 1878, Paris again hosted the Universal Exhibition.
And always at the Champs de Mars.
Bigger, more beautiful, stronger, we need a station again.
We are therefore going to build a more beautiful one, with a renowned architect. It is "Mr Juste Lisch" who is in charge of the plans, a metal structure filled with bricks with large windows.
But still 4 lanes at the quayside.
And + 5 for goods.
Still no Eiffel Tower at the exhibition, but visitors can see the head of a soon-to-be-famous statue as well.
Lisch station is not completely dismantled by the end of the exhibition. We keep it for ... the 1889 exhibition.
The third !
We put that back?
And yes, look closely, what can we see in front of the nascent tower? Lisch station. Always present.
Besides, it's good that there is the train, because much of the steel that makes up the Eiffel Tower was delivered by rail.
We even take the opportunity to connect Champs de Mars station to "Saint Lazare Station" via the Moulineaux line and a brand new bridge.
Slightly curving.
Still used today!
In 1897, the Lisch station was dismantled, and it was rebuilt between "Asnières" and "Bois Collombe". (Paris suburbs)
It is still theoretically being restored there.
Because the railway must continue, along the Seine, towards a new and immense terminal station.
"Invalides Station" exactly in center of Paris.
In 1900, a new Universal Exhibition. The fourth.
And there we can see very very large transport side.
10 platforms, 20 lanes. Just that !
There's even a locomotive depot.
This is needed for the 48 million visitors who will be flocking there !
This photo alone gives an idea of the size of the station.
I repeat, there is no special trick.
One of the most beautiful pages in the history of the City of Light.
After 1900, the tracks were transformed into a freight station. Passenger traffic runs along the Seine as far as Orsay. There is still a stop in front of the Tower.
Since the Eiffel Tower in 1935 it looks like this.
The main traffic is for coal, which at the time was widely used for heating and industries in Paris.
Then with the drop in coal traffic, it became a railcar depot until 1971.
Today we can see the land left free by the rights-of-way.
A soccer field, the Australian Embassy and ... UIC, the International Union of Railways.
The next time you step on the Eiffel Tower, you may be able to hear a train whistling in the distance.
And you will think of the millions of visitors who before you came by train to climb the most beautiful monument in the world.
2/ Comme je vous l’ai montrè dans le thread, le Sénégal ne gère QUE des températures chaude.
Pas de froid et encore moins de période hivernale avec du gel.
Et une voie ferrée, c’est du ballast, des traverses en béton. ET , des rails en acier, des caténaires en cuivre.
3/ Et les métaux, ça réagit énormément à la météo.
Il fait chaud, ça se dilate, il fait froid, ça se contracte.
Un rail qui se dilate, peut faire comme sur la photo.
Une caténaire qui se dilate, elle plie, et casse au premier train qui passe.
Le Sénégal possède un train qui ne connait ni les problèmes caténaires, ni les problèmes de Clim, et les voies qui chauffent lors d’une canicule.
Pourquoi?
Thread technique.⤵️⤵️⤵️
Tout d’abord on va parler du train en lui même, c’est un Regiolis.
À gauche un modèle Sénégalais, à droite un Français.
Ils se ressemblent ? Si si.
Normal, les deux sont fabriqués en France.
C’est quasiment le même modèle sauf un détail.
Les blocs Clim en toiture sont surdimensionnés.
La légende dit même que les radiateurs ont des ailettes supplémentaires en cuivre (j’ai pas pu vérifier).
Le but du jeux étant de climatiser un train qui roule dans un pays chaud, avec des ouvertures de portes fréquentes.
2/ Les gares ont su se transformer, les TER, les TGV, les trains du quotidiens, c’est pas parfait mais pour un pays comme la France, nous avons un très bon niveau de ferroviaire.
Le « système tient » comme on dit en interne.
3/ Par contre, on a complètement raté le virage côté RH.
Je parle de RH en général, je sais qu’il existe de très bonne personne dans ce service. Je vais parler plus « global ».
Tout d’abord, parlons les syndicats. Oui, le sujet sensible.
Bientôt les nouvelles rames Oxygène vont rouler sur Paris Clermont et Paris Toulouse.
Pourquoi elles tomberont moins en panne que les trains actuels?

Comparons une rame Corail qui roule actuellement sur ces lignes, et la future rame @CAF_France
J'ai pris une rame Corail à 6 caisses pour l'exemple, c'est pas tout à fait a la même échelle.
Sur la rame Corail, on a une locomotive.
Sur le toit, deux pantographes captent le courant, un pour le courant mono 25.000 volt, un pour le 1500 Volt continu, suivant le type de courant caténaire.
