フランスのTGV：ヨーロッパ高速鉄道のパイオニア

革命の誕生

1981年9月27日に, フランス大統領フランソワ・ミッテラン 最初の TGVサービス パリ・リヨン駅から リヨン・パルデュー駅へ and わずか2時間後に到着 — 以前は4時間かかっていた旅 従来の急行列車で. The 高速列車 (TGV), meaning "high-speed train," が到来した, and ヨーロッパの鉄道旅行は決して同じではなくなった.

フランスの決定 専用高速ネットワークを開発する 既存の線路をアップグレードするのではなく 先見の明があった. The フランス国営鉄道事業者 SNCF および車両メーカー アルストム 1970年代を費やした 技術を開発する 国家の指導下で, 多額の投資 他の国が削減している時に on rail. その賭けは劇的に成功した: 開業から1年以内に, パリ・リヨン間のTGV 既に利益を上げていた and 航空・鉄道旅行市場の60%を占めていた その路線で.

工学的成果 その時代としては並外れていた. TGV南東部 まったく新しいアプローチを使用した 列車設計への: 軽量アルミニウム車体, 車両間に取り付けられたボギー 各車両の下ではなく (the "Jacobs bogie" arrangement スイスの慣行から借用), and 集中電力システム 専用電気機関車電力車を備えた 列車の両端に. このアーキテクチャにより可能になった TGVがより軽く、空気力学的になった 以前の急行列車より — 本質的な特性 達成と維持のための 時速260キロ, 元々の営業速度.

今日のTGVネットワーク

40年後, フランスが運営する 最も広範な高速鉄道ネットワーク 西ヨーロッパで 路線キロ数で, with over 2,800 km 専用高速線 (大速度線（高速線）) 線路. ネットワークは外側に広がる パリから 国全体に そして隣国へ:

• LGV Sud-Est (1981): Paris–Lyon, the original line, 427 km
• LGV Atlantique (1990): Paris–Tours/Le Mans branches to Bordeaux and Nantes
• LGV Nord (1993): Paris–Lille and onward to the Channel Tunnel
• LGV Méditerranée (2001): Lyon–Marseille/Montpellier
• LGV Est (2007, extended 2016): Paris–Strasbourg, 2h10
• LGV Rhin-Rhône (2011): Dijon–Mulhouse bypass
• LGV Sud-Europe Atlantique (2017): Tours–Bordeaux, cutting Paris-Bordeaux to 2h04
• LGV Bretagne-Pays de la Loire (2017): Le Mans–Rennes, Paris-Rennes in 1h26

The success of the original Paris–Lyon route transformed SNCF's finances and proved the concept beyond reasonable doubt. Ridership on the corridor grew from 7 million passengers per year by conventional train to over 25 million by TGV within a decade. Air France withdrew its Paris–Lyon shuttle within three years of the TGV opening — a model for HSR beating aviation on short-to-medium corridors that has since been replicated ヨーロッパ中 and Asia.

How Fast Does the TGV Go?

Commercial TGVサービスs operate at a maximum of 320 km/h (199 mph), making them among the fastest wheeled trains in regular passenger service worldwide. しかし, the TGV holds a far more dramatic record: on 3 April 2007, a specially modified TGV V150 set reached 574.8 km/h (357 mph) on the LGV Est — a world speed record for conventional wheeled trains that still stands today.

The secret to TGV speed lies not just in powerful motors but in the design of dedicated 線路. LGV lines are built to demanding geometric standards with gentle curves, allowing sustained high speeds. The trains also use a tilting pantograph system and run on 25 kV AC overhead electrification throughout France.

Key Routes and Journey Times

TGV の中でOui vs Ouigo: Choosing Your Product

Since 2017 SNCF has operated two distinct TGV brands on the same infrastructure, targeting different market segments:

TGV の中でOui

TGV の中でOui is the full-service flagship product. Trains depart from central stations in Paris (Gare de Lyon, Gare Montparnasse, Gare de l'Est, Gare du Nord), offer First and Second Class with seat reservations, an on-board café bar, power sockets at every seat, Wi-Fi, and generous luggage allowances. Prices start around €15–20 in Second Class booked well in advance and can rise above €150 at peak times without advance purchase.

Ouigo

Ouigo is SNCF's low-cost TGV product, launched in 2013 to compete with budget airlines and the growing coach market. Trains run from suburban or secondary stations (Paris Marne-la-Vallée, Paris-Massy, Paris-CDG airport) to keep platform fees low. The trade-off: no food service, no Wi-Fi, very strict luggage limits (one bag in the cabin, extra luggage paid separately), and a no-frills environment. Prices start from €10, making Ouigo genuinely competitive with buses for budget travellers willing to accept the constraints. Ouigo has since expanded internationally to Spain (OUIGO España) and within France on more routes.

Cross-Border TGV Services

The TGV does not stop at France's borders. A suite of international services uses TGV technology:

• Eurostar: London–Paris in 2h16 via the Channel Tunnel (now operated as a separate company, formerly using Eurostar e320 trains)
• Thalys/Eurostar: Paris–Brussels in 1h22, Paris–Amsterdam in 3h19, Paris–Cologne in 3h15 (rebranded under Eurostar from 2023)
• TGV Lyria: Paris to Geneva (3h09), Zurich (3h59), Lausanne (3h39) — joint SNCF/SBB venture
• TGV INOUI to Barcelona: Paris–Barcelona in 6h30 via high-speed lines on both sides of the Pyrenees

Booking TGV Tickets: Tips for Getting the Best Deals

TGV tickets operate on a yield-management system similar to airlines. Prices are lowest when booked early and on off-peak journeys, rising as the train fills. Key booking tips:

1. Book up to 4 months in advance: SNCF opens bookings exactly 90 days ahead for most services. The cheapest fares sell out within hours of opening.
2. Use SNCF Connect (app or website) for domestic journeys. Rail.ninja, Trainline, or Omio offer multi-country booking.
3. Consider the Carte Avantage: a subscription card (€49/year) offering 30% off for under-27s, families, or seniors — worthwhile if you take more than 2–3 TGV trips per year.
4. Travel mid-week: Friday evening and Sunday afternoon trains are consistently the most expensive. Tuesday and Wednesday mornings are cheapest.
5. の中でterrail/Eurail pass holders still need to pay a reservation fee (€10–15) on TGVサービスs; this cannot be avoided.

The TGV Experience: What to Expect On Board

Riding a TGV の中でOui is a comfortable, efficient, and distinctly French experience. Trains board from dedicated high-speed platforms at major Paris termini — most famously the vast glass-and-steel shed of Gare de Lyon. Boarding takes place 30 minutes before departure; arrive at least 20 minutes ahead to pass through the ticket barrier and locate your coach, which is marked by a letter on the reservation ticket matching a marker at the platform edge.

First Class (Première) seats are arranged in a 2+1 configuration with wider seats, more legroom, and an at-seat catering trolley service. Second Class (Seconde) is 2+2 seating — more spacious than equivalent airline seats, with adequate legroom for most journeys. Both classes have fold-down tables, power sockets (standard European two-pin), and overhead luggage racks. The on-board Bar Voyageur sells hot drinks, sandwiches, snacks, and a limited range of hot meals; quality and pricing are roughly equivalent to an airport café.

Wi-Fi is available on TGV の中でOui trains at no extra charge, though speed varies considerably に応じて 線路 section and congestion — it is suitable for email and light browsing but not reliable for video streaming. Mobile network coverage on French LGV lines is generally excellent.

The Future: TGV M and New Lines

The next generation of TGV, the TGV M (also called Avelia Horizon), is being delivered from 2024 onwards. Built by アルストム, the TGV M trains carry up to 740 passengers — 20% more than current TGV Duplex sets — while consuming 20% less energy per seat. The trains feature improved accessibility, enhanced Wi-Fi, redesigned interiors, and a modular design allowing configuration between First and Second Class to meet demand patterns. The new design also incorporates enhanced acoustic insulation, making the interior noticeably quieter even at maximum speed.

On the infrastructure side, several new LGV projects are under development, though France's ambitious 1990s-era master plan has slowed due to funding constraints and political debate. Key projects include the LNPN (Paris–Normandie, linking Rouen and Le Havre to the HSR network), the LGV Grand Sud-Ouest (Bordeaux–Toulouse and Bordeaux–Spain), and extensions to Nice and Perpignan. The Bordeaux–Toulouse section is expected to open by 2032, cutting the Paris–Toulouse journey from 4h20 to 3h10 and stimulating significant regeneration in the Garonne corridor.

Despite competition from low-cost carriers and a burgeoning Flixbus network, the TGV remains France's backbone of intercity travel. Its legacy extends far beyond French borders: TGV technology, licensed or derived, underlies the South Korean KTX, Spain's original AVE rolling stock, the Eurostar, and numerous export-market アルストム trainsets. The train that Mitterrand boarded in 1981 sparked a global revolution in surface transport.
