LGVs due to be opened this coming year

Looking forward to 2017, I thought I would do a blog post covering the LGVs (Lignes à Grande Vitesse) that are due to open during 2017.  As many readers will be aware, France has an absolutely fantastic LGV network.  It contains one of only two lines to recoup its own building costs (Paris-Lyon, the other being Tokyo-Osaka).


They have made several journeys much easier.  For instance, I just adore visiting Reims (silly English people think it is pronounced "raymz", whereas "ranz" would be a better approximation), where French kings tended to be crowned.  Thanks to the LGV Est, it can be reached via an interchange at Marne la Vallée-Chessy or Aeroport Paris-Charles de Gaulle TGV stations and Gare de Champagne-Ardenne TGV station (served by both TER trains and a local tram network).


Our pinko-liberal commie socialist president (who has thankfully announced he isn't standing next year) delayed the construction of several lines, but several of the lines already in construction before he entered office are due to enter service in 2017, in addition to the 2nd phase of the LGV Est that opened earlier this year.  The lines are the LGV Bretagne-Pays de la Loire, the LGV Sud-Europe Atlantique and the Contournement Nîmes Montpellier, which I will briefly discuss in turn.


The LGV Bretagne-Pays de la Loire will go from the LGV Atlantique's current terminus near Le Mans to Rennes, expediting train journeys to various stations in Brittany.  Mireille Guiliano says her husband Edward notes the similarities there with England (not exactly to its credit, but anyway).  Just like Mireille, I love the seafood available in Brittany.  Yes, various fish products can be caught near Marseille, but Brittany has a very long coastline and different fish.  As per custom for new passenger-only lines, the line will open with an initial top speed of 320km/h, electrification of 25kV 50Hz and TVM300 (Transmission-Voie-Machine) and ERTMS Level 2 signalling.  The line will have several links to the conventional lines.  Some examples of journey time reductions are: -

  • Paris-Rennes 1h26m (from 2h05m)
  • Paris-Nantes 1h52m (from 2h09m)
  • Paris-St Malo 2h14m (from 2h54m)
  • Paris-Lorient 2h56m (from 3h43m)
  • Paris-Brest 3h25m (from 4h18m)

The LGV Sud-Europe Atlantique will go from the line's current terminus near Tours, where through trains are already able to bypass the city.  From there, it will continue to Ambarès-et-Lagrave (twinned with Norton Radstock, possibly the most gormless and rubbish town in the whole of the UK), which is on the outskirts of Bordeaux, the main urban centre in a region known for its fine wines: - I therefore just adore visiting the city, though this line will not do much to expedite journeys there from Marseille (the Bordeaux-Toulouse section of the GPSO will).  The line will have no new stations, but will have links to the existing intermediate stations on the conventional networks in Châtellerault, Poitiers and Angoulême.  The bypass will allow trains not stopping in these places to proceed full speed ahead to Bordeaux.  The line will be useful for people travelling not just to Bordeaux, but it will also appreciably shorten train journeys to Toulouse and Irún (over the border in Spain, plus the intermediate cities).  This will be particularly useful regarding Toulouse, as the air route between Paris-Orly and Toulouse-Blagnac airports is the busiest in Europe.  Paris-Bordeaux journey times will drop from 3h11m (non-stop) to about two hours.  The line will have an initial maximum speed of 320km/h, with the same power and signalling arrangements as the above lines.


The Contournement Nîmes-Montpellier will bypass Nîmes and allow freight traffic to avoid the centre of Montpellier.  It was decided that the existing Montpellier-St. Roch station would not be able to cope with the increased rail traffic, so the decision was made to build Montpellier-Sud de France station (which will unfortunately not have a tram link until 2020).  The line will bypass the centre of Montpellier, but bring Paris-Montpellier journeys down to about three hours.  It will have an initial operating speed of 220km/h, pending a signalling upgrade, which will allow it to be raised to 300km/h.  The reason for the slightly lower speed is the fact that this line is being designed to accommodate freight traffic, which results in a trade-off between gradients, cants and curvatures (curvature sacrificed for the other two parameters).  It will result in journey time reductions of around 20 minutes for journeys between Paris and Montpellier/Barcelona (and other intermediate destinations), though other train routes, such as the Intercité Bordeaux-Marseille may also use the line.  Bilal enjoys travelling by train to Seville to visit his homies and is learning Spanish (he is apparently doing a good job at mimicking hip-hop Spanish).  When the Nîmes-Perpignan gap is closed, it will be high-speed all the way from Marseille to Seville: - the route for the Montpellier-Perpignan section has been decided.  The power supply will be the same, but the initial signalling will be BAL (Bloc Automatique Lumineux) classique and ERTMS, both Level 1.


2017 looks like it will be a good year for high-speed train travel in France.  Spain's high-speed projects have more or less ground to a halt: - I wonder if we might have caught up with them by the end of 2017 in terms of kilometres of high-speed routes?

London-Marseille trains confirmed!

Recently, I learned that direct London-Marseille trains have finally been confirmed.  Yay!  I am pleased with this, given my unfortunate regular need to visit London on business.  As far as I am concerned, after having spent a few days in London and coming close to death on account of the lack of sophistication, the sooner the train can get me back to Marseille, the better, MDR.  Maybe in the future, Marseille will be the city where everything is happening (or at the least, maybe Paris will regain that title), but until that happens, I will need to keep going to London to ply my trade.
Bilal is also happy on account of the fact that he can visit his "homies" who he met during visits to the Elephant & Castle and Stratford areas of London much more easily.  Both of these areas have direct connections to St. Pancras International via the Thameslink and Southeastern High-Speed services respectively.  He e-mailed his homies in London as soon as he found out the news (his English isn't yet up to phone calls, though he is a regular visitor to http://www.urbandictionary.com for practice) and they were similarly delighted, as they have heard all about La Savine with its rappers from Bilal and can't wait to visit.  He has kept in regular touch with them, sending them occasional gifts, which resulted in them sending him gluten-free products from a local store, plus a cap with "Sorry I'm hip-hop and you're not" written on it, both of which he was delighted to receive.  I wasn't so pleased that they had sent him cake mixes for sickly sweet-looking cakes, but hey, he does not have any flab on account of the enormous amount of exercise he does, so I suppose I shouldn't worry too much about this.
I don't know if they will use the older or the newer rolling stock, but we shall see: - given that the whole route from London to the outskirts of Marseille (bypasses where applicable) uses the TVM (Transmission Voie-Machine) in-cab signalling system, there is no need to use the new rolling stock from a signalling point of view (from what I heard, the lack of space for ERTMS equipment was the main reason they were procured).  There is also no speed advantage, given that the existing rolling stock allows for 300km/h, the maximum speed already allowable on that route (the new rolling stock can do 320km/h).
I am hopeful that the new services will cause ignorant Britons to be cognizant of Marseille's value as a tourist destination.  Obviously, too many tourists is not a good situation: - we certainly don't want drunken British tourists who will just gulp down large quantities of pastis without appreciating the craftsmanship that has gone into the drink and barf up all over the streets.  However, there is a perception that Marseille is a run-down and dangerous city, i.e. that La Savine is a microcosm thereof.  I would welcome the idea of more adventurous and discerning tourists visiting the city to see how wonderfully sophisticated it is and how much it has been regenerated over the years.
Some of the less sophisticated tourists who like hip-hop culture could obviously head for the quarter (or "tchéquar", as Bilal would say, given his tendency to use verlan) of La Savine, where Bilal lives: - though he loves hip-hop fashion, being a sophisticated haute couture person is not one of his strengths.  He and other people in the area would be able to give such people tours to show them the other side of the city, perhaps introducing them to the aspiring rappers, as well as show them where the members of Psy 4 De La Rime and Puissance Nord and Soosol grew up.  Some people have contacted me to ask me why Bilal is my boyfriend, given these things I say about him.  I respond by saying that everyone has their own strengths and weaknesses and Bilal's strengths more than make up for his weaknesses, e.g  what I said in the last post about how he is so attractive that I will give him my full cooperation in whatever attempts he makes to create a large family.  That is before I go into his credentials as a believer.  But that is beside the point.  Even though I don't have any taste for hip-hop culture, I have no doubt that Bilal will be delighted by the influx of tourists who he will be able to introduce to the Marseille hip-hop scene.
The tourists who love great scenery will love Marseille as well.  I have never been to La Savine, though Bilal tells me there are great views of the area from there.  The city is surrounded by mountains and though the Basilica of Notre-Dame de la Garde has no spiritual beauty to speak of (it is part of the Church of Rome), there are great views from the hill it sits upon, both of the city and the Mediterranean Sea.  It doesn't take too long to walk from the Gare de Marseille-St. Charles (or "réga", as Bilal calls it) to the top of the hill: - naturally, a dainty Frenchwoman such as myself would not consider taking the metro (or the "trom", as Bilal calls it).
All in all, Marseille has something for everyone.  It has a huge hip-hop scene for the less discerning tourists and immense sophistication in things such as Pastis de Marseille, Bouillabaise and Frenchwomen saying "la moitié, s'il vous plaît" for the more discerning tourists.  If anyone reading this wants to know more details, or even if they want me to give them a tour of Marseille (I am very happy to do this), they should contact me at mariannegaboriault@gmail.com .
