Was there ever such a plan in place?

Breakthrough is scheduled for 10am local time in the west tube of the Ceneri Base Tunnel.

The stub tunnel in Göschenen is around 300/400 m long, and was built in the 1950s/1960s because at that time some tracks were added to Göschenen station to create the space and loading ramps for the car/truck shuttle. However, as there wasn't enough space to merge these tracks before the old tunnel portal, they entered in a second tunnel that was built and then linked to the main tunnel.

However, as you can see in my post above (#1067), the stub tunnel doesn't merge in the main one, but ends abruptly in the mountain. This was likely a future-proof choice, as it is in these years that a Gotthard motorway started to be imagined. As at the time a 15+ km road tunnel seemed a difficult or impossible project, so one idea was to build a second rail tunnel, so as to have two double track rail tunnels, one for regular trains, and one for trains carrying road vehicles.

This second tunnel would not have been exactly parallel to the existing one. It would have crossed under or above the existing one, because the loading ramp in Göschenen is east of the main tracks, but the ramp in Airolo is on the west. Without switching the side in the mountains, the second tunnel would have arrived on the wrong (east) side of Airolo, with two equally problematic solutions: either new loading ramps on the wast of the station (where there isn't much space), or shuttle trains crossing on a flat junction mainiline trains tor each the ramps on the west side of the station.

Speaking of which, when will the project to convert Goeschenen - Andermatt into a shuttle be completed?

What project? What shuttle? The Göschenen-Andermatt will remain as it is, with through trains going beyond Andermatt (like Göschenen-Andermatt-Brig-Visp). It might just receive new rolling stock, as the existing one is nearing the end of its life.

Then it might loose passengers if the direct Göschenen-Oberalp cable car will be built in the next years. However, it will be for skiers and tourists only, the upper station will be high in the mountains, not near Andermatt nor near any railway station.What project? What shuttle? The Göschenen-Andermatt

Long time ago I read something about Göschenen-Andermatt link having a grade too steep, so they'd be stop running through trains and using a shuttle for that short section instead offering instant connections in Andermatt for trains going on both directions. This could prevent the need of extra-powerful rolling stock in the rest of MGB network

Well, not that the rest of MGB lines is requiring much less power...

Looking at Google Maps, I see what looks like car loading ramps at Goschenen, but not at Airolo. Were they taken away when the highway tunnel was put in?

They are still in place and have been used in 2001 when the road tunnel was closed for 2 months because of a fire.

They are here: https://map.geo.admin.ch/?topic=ech&...787.50&zoom=12 (just south of the southernmost track).

Even the ticket barrier is still in place: https://map.geo.admin.ch/?topic=ech&...599.80&zoom=13 (but this is unused since the opening of the road tunnel in 1980).

Yes it was evaluated. I thought you were thinking about some sort of technically indipendent system, like an atomatic people mover or similar.

This line has a maximum gradient around 180 per mil, the others around 110, so it has some limitations. For instance, in train length, and their type. Only some classes of MGB stock can run on it, either some EMUs or conventional stock with special coupligns: all MGB conventional stock has a central buffer and side chains, while on Göschenen-Andermatt vehicles must have an automatic coupler between them. Some locomotives and driving trailers have an automatic coupling on one side and buffer+chains on the others, so they can have extra coaches attached beyond Andermatt.

I think they will continue as now, but with new stock, as otherwise there would be too many transhipment which would make the train totally unattractive (a Goms valley ==> Zürich passenger would have to change in Andermatt, Göschenen, Erstfeld, and maybe Arth Goldau...).

Have temperatures of the tunnel walls stabilized already? I read it can take up to 3 years for the interior temperature of long tunnels to stabilize.

Planning contract awarded for Lötschberg Base Tunnel track doubling
Monday, February 01, 2016



SWITZERLAND's largest private railway BLS has awarded IG Valbt, a consortium of Swiss engineering companies led by SRP Ingenieur, a contract to plan to the extension of double-track in the Lötschberg Base Tunnel

The 34.6km tunnel was opened in 2007 but in order to bring increasing costs under control only a single track was installed on the 21km stretch between the northern portal near Frutigen and the southern crossover between the running tunnels at Ferden

A special tourist service ("Gottardino", literally "little St. Gotthard") has been unveiled for railfans. Everyday except Monday from 2 August to 27 November two trips will be offered throught the base tunnel, with a stop and a visit of Sedrun safety station. Tickets on sale from 1 April, reservation required and number of seats limited.

The price will be high: 119 CHF (the same in USD, 109 EUR, 176 NZD) for a single one-way trip in the tunnel and a return ticket on the old line with regular timetabled trains. Some reductions for halbtax card or general abo holders.

Times will be:
Flüelen 12.20 - Biasca 14.30
Biasca 16.30 - Flüelen 18.40
These times include the visit to Sedrun. They might well be the only trains calling there for a long time, or might not. Porta Alpina project has been abandoned, but it involved a regular stop, served by regular trains. I think special tour trains like the Gottardino might be offered even after the full opening.

Regular service will start on 11 December, not before. But there might be other public trains in the GBT before that date (but after 1 June), for example delayed InterCity might use the GBT to recover the delay. As until 31 May the responsible is ATG (AlpTransit Gotthard, the building company), until that date no commercial train (including freight) can use the GBT.

Just realized the connection between Gottardino and the old TEE train Gottardo.

Gottardo is just the Italian version of the German name "Gotthard", the name of a medieval bishop which also gave the name to Szentgotthárd.

Yes it is, but will be made public only on 30th May on http://www.progetto-orario.ch/.

Just a little bit more patience and you will be able to discover it

As of today, it's only ten weeks until opening. After many decades of debate, planning and 16+ years of construction the end is so close.
