French term or phrase:chute de véhicule
Les informations fournies par les détecteurs de chute de véhicule sur la voie, les détecteurs de vent, les DBC ainsi que les détecteurs propres à la sécurité du tunnel (détecteurs de fumées, d'incendie -ponctuels et / ou linéaires -détecteurs de présence, etc
Explanation: This one I am sure of - I have actually seen these things, done TGV presentations with visiting delegations, etc.
Since on high speed lines there are no level crossings, there are lots of bridges and viaducts and lots of cuttings. Road bridges often cross the railway lines. SNCF realised that one potential problem was road accidents with vehicles plunging off the bridge on to the railway line. Think of that dreaful accident in the UK not so long ago when a driver wet to sleep and ended up causing a railway accident by driving off the bridge on to the track.
So they designed a system that originally consisted of a sort of metal meshing that is electrically connected and linked to a detector (it may have evolved since). If a vehicle or other heavy weight falls on this mesh it breaks an electrical contact and sets off an alarm, which will transmit an instruction to the onboard signalling system to halt all oncoming trains.
We usually called them "falling vehicle detectors" since there was no "official" UK word.
FYI: the wind detectors are because of potential problems of side wides that can cause excessive uplift in the problems with power supply; the DBC are déctecteurs de boîtes chaudes (hot box detectors) for the axle-boxes to ensure the axles/bogies do not overheat

excessive upfilt and problems - sorry - I am still half asleep

the points issue is irrelevant - I offer you this because you were barking up the wrong tree.
PS - you should wait before grading to see what else may turn up - I suspect you had already made up your mind and took the first answer that confirmed your thinking - a salutory lesson perhaps to remember always to keep an open mind??????
Not wishing to preach but - been there, done that!

I see that I wrote \"wides\" when I meant to write \"winds\" - brain working faster than fingers again
Actually a colleague working on a different part of the same translation had 'vehicle drop detector' which would fit with your take on it. I kind of disagreed, but now I'm having second thoughts. Shall I ask the moderator to ungrade?
Post-grading: IMO more likely to be about road vehicles falling off bridges onto railway lines (http://www.humanite.presse.fr/journal/1998-06-04/1998-06-04-417265).

chute de véhicule
train derailment, train jumping (off) the tracks, running off the tracks
Explanation: I think we can assume that if a train derails it falls (off the tracks) onto the bed, ballast, etc.
-------------------------------------------------- Note added at 28 mins (2006-02-10 00:52:32 GMT) --------------------------------------------------
The derailment detector recognizes when an axle has become derailed by registering and evaluating the impact of the wheels on the sleepers. The driver then receives a warning signal or the emergency brake is automatically applied, reducing consequential damage caused by the derailment
Forget that. I think the business about road vehicles falling onto the tracks is right (I assume the reference to tunnels is unrelated, directly).
To be honest, "véhicule" did bother me, but I assumed it was used to cover different types of "rail vehicle", and I envisaged this system in a tunnel as well ...
