<<"Details on both options can be found on the link above - both avoid the mountain tunnels of course. :)">>
I'm sure that you know that one of the fun parts of the old route is that there are some tunnels that are dug as spirals inside the mountains, and used to gain or lose altitude.
The most famous example is at Wassen, where you can see the church 4 times from the train, as it gains altitude in and out of short tunnels.
