Google translated from French. I guess TGV is supposed to mean 'Tubes a Grande Vitesse,' or 'Tubes of Great Velocity.'Do you know the bike train or TGV (High Speed Tubes)?
The bike is now a transport vehicle human powered rail.
It takes advantage of the recumbent bike ( we talk about it here ) and friction and reduced risk of rail transport.
There are already prototypes to reach 76 km / h average with four cyclists, it's TGV (high speed tubes). One could easily reach 100 Km / h with about thirty passengers.
Some use energy buffer systems for hilly areas (such as electric storage velomobiles??)
It consumes 1 to 1.5 Wh per km, against 5 to 10 Wh / km for a conventional train and 45 Wh / km for a TGV traveling at 300 km / h.
