At speeds of 160 km/h and over, they concluded aerodynamic noise was the most prevalent, but I can't remember where the test locations were and therefore if some of them were in accelleration or braking zones. The study did include frequency distribution graphs, which I didn't study in detail.

They also concluded that at service speed HSTs (at 250 to 285 km/h) were noisier then 'regular' trains (at 160 km/h), but also that an HST at 160 km/h was quieter then the regular train.

HeyHo,

I've got a few questions about the interieur of the TGV Duplex.

There is an "old" and "new" interieur:

Old:

1st class




2nd class



New:


1st class

2nd class



And of course there is the (modernized) low-cost train:

TGV Ouigo




My question:

1) What TGV Duplex series have the old Interieur, and which TGV Duplex have the new one?

2) Is there another TGV Duplex Interieur design than the three I showed? Did I forget one?

3) Any plans to modernize the "old" TGV Duplex design? Is that still the original one, or has it been changed already?


There are First generation Duplex (two deliveries), Reseau Duplex, Dayse and 2N2 trains ))

Thanks for your information!

Phillip

A DIRECT TGV service between Paris and Barcelona will enter service on December 15.
Quote:
...The two countries' high-speed networks were linked earlier this year but passengers still had to change trains at Figueres, near the French border, a manoeuvre that added 20 minutes to the journey time.

Previously, rail passengers had to take an overnight train to make the trip.

Spain's RENFE railways operator and France's SNCF will run the line together.

SNCF said the new daily services comprised two return trips between Paris and Barcelona, one return trip between Lyon and Barcelona and one return trip between Toulouse and Barcelona...

The entirely new line is 340 km (210 miles) long (that's one-quarter the length of the Beijing-Shanghai high-speed line that was opened in 2011, and slightly longer than the future HS2 line from London to Manchester). The Tours-Bordeaux high-speed line is expected to cost 10.7 billion US dollars to build (although final cost could be closer to 14 billion US dollars). For comparison, the Beijing-Shanghai high-speed line cost 35.8 billion US dollars to build. 5,000 construction workers are currently working along the 340 km of the line between Tours and Bordeaux.

This line will enable high-speed TGV trains to run at 320 km per hour (200 miles per hour) when it opens in 2017, and so it will take only 2 hours and 5 minutes to go from Paris to Bordeaux (two cities as far apart as NYC and Montréal, or LA and San Jose; the section from Paris to Tours was already opened to traffic in 1990).

In this photo tour, we'll start at the southern end of the line near Bordeaux, then move north towards the northern end of the line at Tours, then back south to Bordeaux where we'll finish the tour. The photos here come from the official website of the Tours-Bordeaux high-speed line (http://www.lgv-sea-tours-bordeaux.fr) and from the website of Patrick Le Doaré (http://www.pascal-ledoare.com).

Crossing the A10 motorway/freeway near Poitiers:

Viaduct in the suburbs of Poitiers that will link the high-speed line to the central train station of Poitiers:
(the Poitiers city hall has insisted on having high-speed TGV trains arriving right in the city center instead of building a new train station on the high-speed line in the suburbs of the city, which has necessitated building this very costly viaduct to cross the maze of suburban freeways and railway lines)

Archaeological remains unearthed under the path of the high-speed line south of Tours:
(they found a Neolithic necropolis from the 4th millennium BC, a Gallo-Roman temple, and some Medieval structures)

Approaching Bordeaux, the high-speed line must cross famous Bordeaux vineyards, wetlands and ponds, suburban freeways, and residential areas:

Arriving at Bordeaux:
(historically as large as Barcelona or Hamburg, and with one of the most impressive riverfronts in Europe, the city completely stagnated in the 19th century and early 20th century due to the loss of most French American colonies and the collapsing fertility rate of southern France, but it survived WW2 intact because it was out of range of the Luftwaffe in 1940, and far-away from the battle zones in 1944-1945)

I have a feeling that if Californian farmers saw the extent of destruction during construction, they would go even nuttier.

Not that they aren't already, but I can see how these pictures can potentially add more fuel to the fire.

In any case, why is the travel time more than 2 hours for a 340km line with an operating speed of 320kmh?

I reckon the average speed on this route is lower, you have to take into account the approaches to stations/terminals on conventional speed track, the interlockings, etc.

The 2:05 is for the trip PARIS - Bordeaux which is around 500 km ( In a straight line 580 driving distance)

The 340 km new line is from Tours to Bordeaux .

That kind of pictures is allways impressive but things will change quickly after construction end. Countryscape will be healed in a few years.

The thing is: if those pictures were of a new motorway, would they be complaining as well?

Probably not... But the next entry/exit complex on the new motorway would
probably be only a couple of miles away, and they would use it everyday.
While the nearest train station will be a good hundredts miles away, and they
will use it twice a year, if ever. We have to accept this, fast rail lines are
made for for urban citizens, not for people living in the country side, who
have to take all inconveniences without palating any of the advantages.

Tohoku Shinkansen between Sendai and Shin-Aomori is 349,5 km and has 11 intermediate stations. How many stations does LGV between Tours and Bordeaux have?

None on the HSL.
All stations are located outside the HSL, on the classic line, to which the TGVs get through branch lines.
The stations where the TGVs can call are St Pierre des Corps (Tours), Châtellerault, Poitiers, Angoulême, and Bordeaux St Jean.
Not sure about Futuroscope station...
Jonzac, Libourne, and Coutras stations are out of reach of the HSL.

I must admit I do not know very much about Japan, but I expect this route
to be in a landscape with a quite high population density, which sort of
justifies those intermediate stops.

In France, outside big cities, population is scarce. No other stations can be
justified than those cited by 437.001 above. Which means, spaced by 80 km
or so. And not served by the majority of the trains (you can look at
schedules for lines already in service to get an idea on how many trains will
make intermediate stops).

Now, how often in a year does a typical farmer or countryside person take a
trip that will begin by a 50 km car ride to the next train station ? In
comparison, how often in a year could he use a motorway whose next exit is
10 km away ?

Tohoku Shinkansen serves Tohoku region which is relatively sparsely settled compared to rest of Japan.
Miyagi prefecture - 7285 square km, 2,338 million people, 321 per square km
Iwate prefecture - 15 278 square km, 1,331 million people, 90 per square km
Aomori prefecture - 9606 square km, 1,373 million people, 154 per square km

That said, I expect that these prefectures contain appreciable mountain areas even more sparsely settled, and Shinkansen follows plains and valleys where the population is concentrated.
