Very good, you get 4 out of 4. Oops, I just realized that I forgot to put in one other question, and that was: What is the maximum grade on this viaduct ?
Have you been to Brusio ? I tried to find a good video of this place but none of them really satisfied me. But is it neat to hear the screeching of the wheel flanges as they rub on the rails in the turns. Attached is a pretty nice photo of the viaduct. I also wonder how active those rock slides we see are.

Maximum grade is 7 degrees (according to Wiki).
I’ve been through Brusio and enjoyed the spirals when I travelled on the Bernina Express a few years back.
If I was an engineer I’d might say those rock screes are fairly stable, but as I’ve never gained such qualification I just made that up.

Yup, 7 degrees is the answer.
The reason I mentioned that rock is that if they had not kept the track as elevated as they did before getting to the spiral, it might have been more vulnerable to damage from a rockslide. That said, I am not an engineer either, although it would be fun to ride with a train engineer along some Swiss rails.

Bigger is better, 😉

Standard gauge, of course. Meter gauge can take smaller radius curves.

I said “1. Brusio Spiral Viaduct (for other names see en.wikipedia.org/wiki/Brusio_spiral_viaduct).” in my first response to this thread. Slowpoke mis-credited it to you. Clear?
