Most HSR systems are country-by-country and the ones currently operating in Europe are:
TGV - France. These run several types including the Reseau, Duplex, Atlantique, and ex-Eurostar.
- The Reseau (French for network), as its name implies, is designed to run on the entire TGV network and sometimes into other neighborhing countries like Belgium or Switzerland. BTW, these are undergoing refurbishment with the new interiors designed by Christian Lacroix - something completely different.
- The Duplex is simply a double-level TGV that runs primarily between Paris and Lyon and sometimes down to Marseille and AFAIK operates exclusively from the Gare du Lyon.
- Atlantique - predecessor to the Duplex
- ex-Eurostar - Old Eurostar trainsets that run exlusively in France on the same routes as the TGV Reseau, but primarily between Paris and Lille and its environs.
- New!! TGV-Est is a new trainset that should debut in 2007 when the line east (hence the name) to Metz and Strasbourg opens up.
The destinations are too many to name, but some of the major lines are between Paris and Calais via LIlle, Paris to Marseille, and Paris to Bordeaux. The line to Strasbourg should open up its first portion next year.
ICE-1, ICE-2, and ICE-3 - Germany has three models. As the names imply they are simply generational developments, though the ICE-3 are multi-voltage (meaning they can run on other countries networks like into Belgium) and the power car also has passenger seating plus a lounge where you can look out the front window!! The driver's seat is set low so passengers can see out! BTW - if you ride, bring your earphones since the music selection is always interesting and you can listen to the radio.
As with France, the destinations are too many to name, but the line between Frankfurt and Cologne is not be missed.
Spain - AVE - A talgo built model that runs to Seville and, if it isn't already, to Barcelona in the near future.
Sweden - X2000. Don't know much about this one, but I'm guessing it runs between Stockholm and Gothenburg and onto Copenhagen across the Oresund bridge.
Italy - Eurostar. Tilting trains, but there are dedicated high-speed tracks between Rome and Bologna, Firenze, and I'm not sure in the Milan line is open yet.
The two multi-national HSR are the:
Eurostar - lovely white trains with blue and gold trim that run between London and Paris or Brussels
Thalys - Red trains. As noted, two types. PBA - The original with two windows that can run only between Paris, Brussels, and Amsterdam, and the PBKA - with one window that can also go to Cologne.
There will also be in Jan 2007 the HST-Zuid between Amsterdam and Brussels that is a joint venture between KLM and the Dutch rail operator that will have its own livery and train sets. Also, in case you're curious, Thalys and Eurostar companies are both actually based in Brussels and are therefore Belgian companies.
Hope this helps.
Atlanta - within two and a half hours of . . . the edge of its suburbs
