Am I missing something? 50 > 18

Channel Tunnel is rail only; 'road and rail' probably used here to mean both means of transport.

yeah - iirc the concern was that car drivers would be too unpredictable / bored driving 21 miles in a tunnel - so you just drive your car onto a train

And said train is a tunnel too, you can just drive though it. Even has two levels in the car segment (not the truck one obviously). It's really cool.

yeah - I recommend having an overheight car (eg roof box) - then you get to ride in the high ceilinged carriage used by large passenger vehicles such as busses ... no extra cost, very roomy sense of space and smooth motion

btw trucks (as opposed to passanger carrying busses and coaches) are unhitched and take different trains with the drivers all in a dedicated people carriage next to the loco - guess they must have known about truck fires and separation of people from goods

Also, it could cause messy accidents that are hard to reach. I think it was a good choice, if you see what happened in other long road tunnels: https://www.theguardian.com/world/2001/oct/26/jonhenley1

The Chunnel had a train fire once but it was not as bad.

I've been through the Austrian Arlberg Road Tunnel a couple of times, which is just 13km and I was super tired from the hyper focus, as I was leaving it. Can't really imagine doing it for 50km.

I suppose they're being pedantic in that the Channel Tunnel only carries rail traffic.

The Chunnel is rail only.
