Thanks Kato , very interesting. Seems to me the way to increase capacity in the future is to use technology to reduce train spacing/ increase the number of slots per hour.
I'm thinking electronic brake control , and a positive train control system that measures down to the metre or so .

As a note on this older post btw:

Both the Gotthard Base Tunnel and Lötschberg Base Tunnel are a contractual obligation Switzerland agreed to mandated by the 1992 Agreement between the European Economic Community and the Swiss Confederation on the Carriage of Goods by Road and Rail.
That treaty basically established the reciprocal basis of mutual transport access between Switzerland and the European Union, as a step towards allowing Switzerland access to the European Economic Area, and as the price for that established certain investments that Switzerland had to make - mostly those two tunnels and a certain guaranteed amount of trains and goods ("consignments" transited even before that starting in 1994.

To be fair this treaty was rushed through negotiations and signed only two weeks (!) after the Swiss in a referendum rejected joining the European Union - the Swiss government was kinda in a hurry after that to at least get economic access. It is rather ... favourable to the EU, altogether, especially since where it mandates similar future infrastructure investments on the EU side those are far more vague in language ("shall increase capacity on route..." and similar).

Competing projects such as the Brenner Base Tunnel or the TELT Turin - Lyon tunnel which only run on EU territory are 40% cofinanced by the EU.

The minimum train spacing already is 3 minutes distance between trains in rolling blocks using ETCS Level 2.

The problem is the overlapping of speed vectors, the last concept apparently assigned alternating 200 km/h and 160 km/h passenger trains at 30-minute frequency with one package of three 100 km/h freight trains and one package of three 120 km/h freight trains between them.

There are some (mostly pro-freight, as well as anti-Gotthard) counterproposals by lobby groups that either:
a) want to banish passenger trains into a single hourly window (of two trains following each other) that by their calculation would allow spacing for up to eight 100 km/h freight trains between them or
b) further propose going to all-identical-low-speed minimal-spacing freight train spacing (with no higher-speed passenger trains) at an estimated up to 17 trains per hour.
