The Mission: Impossible Eurostar scene was always gripping until I realised it was lacking overhead lines!
You beat me by ONE MINUTE! I was scrolling through the posts thinking that nobody had mentioned it...
Surely the most error-strewn railway scene from any movie? If anyone has a scene with more mistakes, here's your challenge. Let's start with the obvious and work down...
1 - It was a TGV Atlantique (not a Eurostar as it should be) running on a track with NO overhead lines. FAIL. Even if it had been a 373 - there was no 3rd rail and it was going way to fast for 3rd rail anyway.
2 - It wasn't the line to the channel tunnel - it was actually "filmed" (i.e., the background without the TGV) in Ayrshire and the TGV was CGI'd in later.
3 - The "channel tunnel" wasn't the channel tunnel - it had no Dollands Moor yard, no le Shuttle terminal and no redcution of speed on entry, but it was supposed to be the Channel Tunnel as described in the script and the news report at the end of the movie.
4 - The little helicopter used in the movie can't fly at 300km/h so wouldn't be able to keep up with a TGV flat out.
5 - The train is running on the RH track...
6 - In the tunnel another train passes right next to the one Tom Cruise is on... the Channel Tunnel has separate bores... And the horn tone was all wrong.
7 - The helicopter would be of course utterly detroyed when it's rotor clipped the tunnel wall.
8 - When Tom Cruise climbs on to the roof of the power car (holding on to the pantograph that's not being used), he got there through a small hatch door. Now, TGV and Eurostar power cars do indeed have a small hatch beneath the pantograph well, but it's usuall locked out of use when not in depot for obvious safety reasons. The real clanger here is that he was in a baggage compartment when he opened it from the inside... in reality, he'd be between 2 motor-block control units.
9 - It seems that the TGV braked to a standstill from 300kmh in a time that would suggest a VERY effective emergency stop, yet the helicopter doesn't run into the back of it except of course at the last second when the battered blade stops about 1" from Cruise's neck.
I actually love the movie, but every time I see that scene, it makes me cringe.
