Geothermal heat, more likely, or did I miss something?
Geothermal heat is due to radioactive decay in the earth's core, so you're technically both correct.

Ahead of schedule based on an adjusted schedule during construction. They are slightly behind the originally planned schedule (a couple years). Obviously this is still a very well executed project overall.
Well obviously it's part of the Requirement Engineering process to adjust the schedule when the requirements change.
"Nine workers died during the work." Although on-time or early and within budget, it is still a dangerous job to do. That is 0.346% of the total workforce (2600).
And important as well: likely more friendly to the environment. It's not all about economics.
I was very surprised to read how little Swiss labor (14%) was used in its construction. Most of the labor was Italian (29%): http://www.bloomberg.com/news/articles/2016-05-30/swiss-made...
There's a great 360° video on Youtube that shows both the tunnel as well as the Gotthard massif through which the tunnel leads. It's in German, but the visuals are impressive on their own. https://www.youtube.com/watch?v=qDSCtXvL51o

Radioactive decay is a component of geothermal heat, but it is not all of it, quite a large chunk of it is simply residual heat from time of the formation of the planet.
1. Ok most :)
"... longest and deepest rail tunnel ..." and "... delivered on time and within budget ..." Only in Switzerland, I guess. :) I wish there were better write ups of how the planning for this came together and what differs from other somewhat similar huge projects.

It cuts the Zürich-Milan journey time for passenger trains by about an hour (from 173 to 111 minutes) accelerating train trips from Germany/Switzerland to Italy significantly.
I don't get this. Zurich is in Switzerland. I don't think even with this tunnel opening we will be getting from Zurich to Milan in under 2 hours... Are your numbers wrong? Edit: we will be looking at journey times of about 170 minutes from Zurich to Milan AFTER the tunnel opens.

OMG I just understood what you meant with 360! You can swipe to the direction you want, like in Quicktime VR, but animated! I didn't know Youtube made it possible! The video was just showing the rails, I thought it was boring until I understood the concept.
BTW Make sure to open the video in Chrome or Opera, the 360 thing does not work in Firefox
