the T stands for TRAIN - I insist (not for très). Have a look at different TGV-web-pages (it is always and only TRAIN!).
"The TGV (Train à Grande Vitesse) is the French high speed train. Of course, there is no such thing as the TGV; there are many significant differences among the 350-odd trainsets in service today, and the name TGV refers to much more than just the trains. Indeed, the TGV is a system which comprises train, track, and signalling technologies that when combined make high speeds (typically 300 km/h, or 186 mph) possible. The TGV system is owned and operated by SNCF, the French national railways, and is an integral part of French rail travel."
