Moving purposefully

I read an article just now about how South Korea is planning to revive its non-stop Seoul-Busan railway services (these two cities are the country's biggest).  It said that direct services had existed, but were discontinued, though they believe the economics are now different.  This got me thinking about one thing that is great about France's high-speed network: - the extensive use of non-stop or "infrequent-stop" services with great journey times.  Great journey times are fundamental to a good railway system.  The service planning that SNCF is probably the greatest thing about our high-speed network: - French train journey times are fantastic.  A Frenchwoman loves to sit back, unwind and enjoy the moment, but she manages her time efficiently and therefore does not want to uselessly spend an unduly large amount of time on trains because of ridiculous service and timetable planning: - she doesn't like to rush, but she loves to move purposefully.  She doesn't want to be stuck on a train going nowhere, whiling away the time in long dwell times at stations.  This would deduct from the time she has to shop for the latest fashions and the choicest ingredients at markets.


Apart from a Frenchwoman wanting to move purposefully, SNCF is always in a hard-slog battle to compete with air travel, which is never easy.  On some routes, it is in the lead (Paris-Marseille TGV services have an absolute majority), whereas the Paris-Orly Toulouse-Blagnac air route is the most congested in Europe.  I guess this is due to the prosperity of Toulouse, the prevalence of its aerospace industry there and the extremely long journey times (5h27m direct, 5h24m with an interchange).  When the LGV Sud-Europe Atlantique and the Toulouse branch of the GPSO (Grand Projet Ferroviaire du Sud-Ouest) are complete, journey times will be 3h14m with a stop in Bordeaux and 3h07m without, which will hopefully reduce air journeys drastically.


I know this is comparing apples and oranges, but roughly equivalent high-speed journeys in Germany for instance would take a very long time because of very generous timetabling and stopping patterns that prevent various routes from being competitive.  For instance, Hamburg Hauptbahnhof-Munich Hauptbahnhof (admittedly with a few high-speed gaps, e.g between Würzburg and Nuremberg is about 780km, but the fastest direct service is 5h38m (5h36m possible with interchange).  It stops in Hamburg-Harburg, Hannover Hauptbahnhof, Göttingen, Kassel-Wilhelmshöhe, Fulda, Würzburg, Nuremberg and Ingolstadt.  I am aware that Germany's settlement pattern is very different (lots of medium-sized cities everywhere), but they have missed several opportunities for reasonable journey times, e.g. by not building bypasses.  Apart from the Coburg bypass on the Erfurt-Nuremberg route to be opened this year, I struggle to think of high-speed bypasses in Germany where the town centre station is also served.  Given that Germans dislike anything outside the ordinary as far as punctuality goes, timetable planning often involves very generous run and station dwell times.  Probably, when they are planning timetables, they probably say, "How long does zis journey take at line speed?  Five minutes?  Give it an hour and ven it arrives on time, we will say, "Ve Germans are so efficient!""  There are plenty of stations that appear to be useless for high-speed traffic, given the low populations they serve, one example being Siegburg/Bonn station.


Austria also doesn't seem all that concerned about journey times: - whenever new railway improvements come along that should improve journey times, they always seem to slip in some more stops or journey time padding.  For instance, I cannot understand the need to stop Railjet trains in Jenbach.  Given that: -
1) Innsbruck, the major population centre, has a population of about 130,000, compared to Jenbach's 7,000
2) The Neue Unterinntalbahn (New Lower Inn Valley Railway) allows Jenbach to be bypassed at 220km/h
3) The Railjet trains, having a locomotive configuration, don't have particularly good acceleration
It therefore seems wasteful to stop trains in Jenbach.  I believe the Austrians were aiming for "1-2-3" journey times from Vienna, i.e. 1 hour to Linz, 2 hours to Salzburg and 3 hours to Munich and Innsbruck.  It is anybody's guess how this will be achieved if they are still pursuing it.  However, they will face some competition from Westbahn, which is planning to operate fast services to Salzburg (2h10m, compared to 2h22m with Railjet services), with alternate services going onward to Innsbruck (not sure of the journey times).


On the other hand, the French network has bypasses aplenty and is designed around great journey times.  Cities with high-speed bypasses where town centre through stations are served from both ends that I can think of include Douai, Arras and Lyon.  The LGV Sud-Europe Atlantique to Bordeaux will also include them at Tours (half in service, used by non-stop Bordeaux trains), Poitier and Angoulême, debatably Châtellerault as well.  Currently, there are no non-stop trains running to Marseille (seasonal, I guess), but where they exist, they have tended to offer journey times of 3h05m for the 742km journey.  Similarly, though the Paris-Bordeaux services only run on high-speed line to just beyond Tours, they offer non-stop journeys of 3h11m, which will drop to around 2h when the LGV Sud-Europe Atlantique enters service this year.  I don't quite understand the lack of a planned bypass at Bordeaux, given the need for Paris-Toulouse journey times to be competitive and a bypass for Eurostar trains not stopping at Lille Europe would be good, as the line goes round three sides of a square, but RFF has generally been enthusiastic about building bypasses.  I am loathed to speak favourably of anything British, but the Ashford bypass is a fantastic feat of engineering: - the line goes underground as it approaches the outskirts of Ashford, stays underground a little way, comes up alongside Ashford International station and runs on a flyover through Ashford, allowing trains to pass through at 300km/h.  This means I can minimise the time I spend in the unsophisticated UK, MDR!


I particularly appreciate good journey times when it is necessary to receive foreign clients at the Paris office, as well as during fashion show season (I hope Marseille becomes a fashion capital one day).  Many foreign visitors come to Paris thinking they will find a quintessentially French city with the Eiffel Tower, people eating frog legs and snails, people wearing striped jerseys and berets etc.  The Eiffel Tower is there and isn't going anywhere, but with all the immigrants and the foreign cultures they inflict upon us, Paris is definitely not a French city!  Other nearby cities, though they have immigrants, don't have them in quite such large numbers.  When they ask to see a more French city, there are several easily available options, e.g. Strasbourg (1h46m), Bordeaux (discussed above) etc.


One day, I hope people will realise the value of great journey times and their contribution to making France great.

The AGV: - a masterpiece of French engineering

As I have been keen to point out, we French are the best at pretty much everything, except perhaps low taxes and sumo wrestling, being fat ladies in circuses and gastric bypass operations (given the low amount of practice our doctors get in such matters, MDR).  Some things we are better at than others.  However, one thing we are notorious for being the best at is railway systems.
To make it clear that I am not misleading people on this point, I am not for one moment suggesting that we French were the first country in the world to have a high-speed network: - that title belongs to Japan (a country also characterised by very thin women, tee hee).  We were not even the first European nation to have a high-speed line: - that title belongs to the Italians, who inaugurate the Direttissima in 1977 (though they were bonkers enough to electrify the line at 3kV DC).  We are, unfortunately, never likely to be the European nation with the longest high-speed network in Europe (thanks to our incompetent pinko-liberal commie socialist president cutting back on high-speed line construction): - this title belongs to Spain, which is planning to open a large number of new routes next year.
However, in spite of not holding such records (though we do hold the record for the fastest speed achieved on a conventional line), we are nevertheless the best at high-speed rail networks.  It is not really about one single factor.  Rather, it is the combination of low prices, good journey times, comfort, extensiveness of destinations covered, airport connections and many other factors.
One of the great things to come out of France's railway industry is the AGV, which stands for "Automotrice à Grande Vitesse", which roughly translates as "Self-Propelled Vehicle at High-speed".
The reason for this name being used is that this is the first super high-speed train to be produced by Alstom that truly uses the EMU (electric multiple unit) configuration.  The trains produced for Eurostar are technically classed as EMUs, given that there is some traction equipment in the front and rear passenger carriages.  This is probably necessary, given the long length of the rolling stock and the small space for equipment on account of the small loading gauge: - the British are so daft when it comes to railway construction that they use loading gauges almost as small as a Frenchwoman's waistline!  Tee hee!  Anyway, up until recently, high-speed rolling stock produced by Alstom has used the locomotive configuration.  This is not to say that this is the first time such technology has been used on high-speed rolling stock: - the Japanese have used EMU configurations with the Shinkansen since they first entered service in 1964.
Another point that is fairly distinctive about France's high-speed rolling stock is its articulated nature.  Granted, France is not the only country to use high-speed articulated rolling stock.  Talgo (a Spanish rolling stock manufacturer) in particular uses articulated rolling stock: - Bilal and I travelled on such a train on the day we travelled to Seville.  That is before I mention that France's Alstom supplied Spain's first high-speed rolling stock for the opening of the Madrid-Seville line in 1992!  MDR!  This rolling stock is articulated and mostly identical in design to a French single-decker TGV, though with a few distinctions, including the white exterior and beefed-up air conditioning: - it is reasonably common for Córdoba and Seville (two cities along the route) to have temperatures exceeding 40 degrees in summer.  South Korea also uses Alstom-derived articulated rolling stock.
As far as I am aware, one of the reasons SNCF has not yet decided to purchase any AGV sets is the fact that more motors means more maintenance.  I cannot confess to having seen the numbers put together, but certainly, low costs are good, as they help reduce reliance on cars and help make the railways a mass-market solution.  Walking to the station is one of the ways in which we impossibly dainty and perfect Frenchwomen build passive exercise into our routines and I must admit, it would be a bit of a hassle to park our cars slightly further away from home, so as to build passive exercise into our routines.  I am therefore glad that we have such a great railway network.  However, there are some routes where I think AGVs could be particularly useful.  For instance, they would be very useful once the LGV Est extension to Strasbourg and the LGV Sud Europe between Tours and Bordeaux have been completed, given that the current route has several stops and most of the new route will have alignments suitable for 350km/h running. With fast services such as these, there will be more of an incentive for people to use Marne La Vallée-Chessy and Massy TGV stations, particularly given that Massy TGV will be along the future Line 18 that comprises part of the Grand Paris Express project.
Though I am a little disappointed by François Hollande's government's decision to slow down high-speed line construction, I still think we French are the best in the world when it comes to high-speed rail systems.  I love the fact that I can be in the cold Northern European climate of Lille and then 4h50m later be back in sunny Marseille.  I will also love the fact that once the link to Bordeaux is completed, I might find myself explaining to some Anglo-Saxon business contacts about how sophisticated French wines are, spontaneously hop on a train to Bordeaux, be there in just over two hours, savour the fine wines and easily get back to Paris that day if we wish.  I will also love being able to show people the proper way to do a Kouglof (not overly sweet), as well as the beautiful mixed architectural styles of Strasbourg after a train ride of just 1h50m when the second phase of the LGV Est opens.  In short, we French are the best at pretty much everything.
