I traveled on a double-decker train between France and Switzerland at 199mph. See inside the TGV Lyria, which costs as little as $50.

Last month, I was in Geneva to attend a business aviation conference.

Jeff Bezos owns a $10 million Swiss private jet. See inside the Pilatus PC-24 with its unusual toilet in the galley.

While I flew into the city, I traveled back to London via train — starting with the TGV from Geneva to Paris.

TGV — pronounced in French as tay-zhay-vay — stands for train à grande vitesse, meaning high-speed train.

It's operated by the TGV Duplex, which has 510 seats — 332 in second class and 183 in first.

That's a higher capacity than the 469 seats in British Airways' A380 superjumbo jet.

I booked my seat online and got a QR code ticket, but you can also get one in person at the station. A one-way ticket in advance is as cheap as 47 euros ($50).

At Geneva, the TGV platforms were separate from the rest. I walked through a narrow corridor where two border-control officers stood watching people.

The train arrived about 15 minutes before departure which gave me plenty of time to find the right carriage.

I was impressed by how many luggage racks there were, with one on either side by the carriage entrance...

... As well as one between seats.

There was also space for smaller bags above the seats.

About five minutes before departure, there was an announcement reminding everyone to label their luggage with their name and address.

Helpfully, the announcements were all delivered in French and English.

I was on the lower deck in standard class in a 38-seat car. Tables for groups of four were at the front and back, while the other seats were in pairs.

It was pretty simple to find my seat — around one of the tables — with these numbers and illustrations of aisle or window.

It's easier to move around and get into your seat since the table extends and folds out.

Underneath, there was only one outlet for two seats, which isn't ideal.

The seats also have a recline button on the armrest, and I found them to be much comfier than a typical plane seat.

We set off at a slower speed, enjoying some beautiful views of the eastern French region of Auvergne-Rhône-Alpes.

After stopping at a couple of small French towns, the train joined the high-speed line towards Paris where it can reach 199 mph.

The black line shows the 1 hour 25 minutes it took to reach Bourg-en-Bresse. Onward to Paris was a similar time, another hour and 53 minutes, thanks to the LGV Sud-Est.

After leaving Bourg-en-Bresse the conductor gave the only announcement that wasn't repeated in English — something about us now traveling at high speed and "bon voyage."

A few minutes later, the ticket inspector came by. He was friendly as he scanned my QR code.

Looking out the window, I could tell the train was going much faster. Watching the countryside whizz by was a great sight (even if the windows were a bit dirty).

I've traveled on an Italian high-speed train before, the Frecciarossa, which feels similarly speedy at around 190 mph. Along with the TGV, they feel far more advanced than the 125 mph reached by British trains, while the fastest Amtrak train travels at 150 mph.

Then I went to check out some more of the train, which had some relatively spacious bathrooms.

It had a peg for a jacket or bag, an electric shaver outlet, and a handle that was useful for those bumpy parts of the journey.

The toilets on the upper deck looked to be slightly smaller.

On the upper deck, you can find the TGV Duplex's pièce de résistance...

The café car was impressively modern and bright, with long curved countertops and trash cans underneath.

The menu was pretty extensive, with sandwiches, cheeseburgers, pizzas, and a croque monsieur, among others.

You can also buy tickets for the Paris Métro on board.

I managed to order with my rudimentary French skills, and when I didn't understand the response, the friendly cashier helpfully repeated it in English as well: "Rien d'autre? Anything else?"

I haven't spent much time in France and only remember bits of what I studied at school when I was 14. But thanks to that small interaction I have another phrase that'll stay in my mental dictionary.

There were a couple of spaces with stools ...

... but I preferred to stretch my legs a bit and lean against the counter while taking in the landscapes.

Returning to my seat, I had a laptop and a book with me, but I was happier spending much of the journey just listening to my headphones and appreciating the French countryside.

After three hours and 18 minutes, we made it to Paris Gare de Lyon on time. TGV Lyria staff hung around the platform to help people with onward journeys.

It was about the same time as a flight between Geneva and Paris, taking into account the extra time needed for security and traveling from the airport to the city center.

While it would've been quicker to fly directly home to London (the Eurostar was another few hours), I certainly don't have any regrets because it was more relaxing and gave me more time to enjoy the country.
