It would be extremely easy to go onto a TGV (with a ticket), put a suitcase in the luggage compartment with a bomb in it, and not board the train. There would be zero risk for the terrorist. There are no baggage check, and no one makes sure the owners of each luggage are on board. In theory each suitcase should have a label with the owner's name and address, but that too is not checked (and even if it was it would be the easiest thing to fake). I just don't understand why it doesn't happen. I think the main reason is because there are very few actual terrorists, contrary to what everyone wants us to believe.
