I guess lights are on because the tunnel is a construction site. It is also an indirect way to test the reliability of the tunnel's emergency lighting system.

There is no point leaving a tunnel well-lit when in use. Bright interior of trains + dark tunnel = less claustrophobic impression on passengers.

Thanks for that. In all the railway tunnels I've been through in New Zealand, none have had any kind of lighting. The few road tunnels we have (if they're modern and lined) have usually had some lighting going 24/7.

No, lights are not on normally in a tunnel during operation. There are a few indicator lights, so that the driver can have an idea of his progress.

Sure. Road vehicle drivers need a clear vision of the track they are driving over as there are no passive guidance system (like rails are for trains) for road vehicles - yet.

A modern road tunnel has to have much more stringent and sophisticated lighting, signaling and fire extinguishing capabilities than a rail tunnel because the potential for incidents is greater. 1999-2002 have shown us that with the Mt. Blanc (1999), St. Gotthard (2001) and Fréjus (2002) tunnel fires with many deaths (particularly the first incident).

A few photos taken yesterday, 28 May 2011, during the first public trip by standard gauge train into the GBT. These trains entered the tunnel for about 2 km, while the track continues for about 13 km in the west tube until a point just before Faido station. The east tube is still used to supply the other parts of the construction site, and hosts narrow gauge tracks for the service trains.

I didn't notice that one of the two cameras I used was set with the wrong time, thank you

I have two cameras, one of which (the Sony DSC-WX1) has accumulated dust on the lenses which becomes very visible using the zoom...even if I had not used it in dusty places before. That's why I use it only in these occasions: it's too late to worry about dust now...

Yes, every year there are one or two open days. Visits are also possible on other days if there are enough people.

Status of Work on the Gotthard and Ceneri
04.06.2011
On May 19, 2011, at 3:03 pm in Cross Gallery 91 in the Faido section, the final blast in the Gotthard Base Tunnel took place. After 18 years, this marks the completion of driving in the Gotthard Base Tunnel.

Lining work in the Erstfeld, Sedrun and Faido sections is progressing according to plan. Of the total of 114.6 km of lining work, 114.6 km (100%) of the invert and 100.86 km (88%) of the vault have now been concreted. At Bodio West, installation of the railway infrastructure for the test section is in progress.

Of the total of 39.78 km of the Ceneri Base Tunnel, at the end of May 2011, 13.14 km, or 33%, had been excavated. Concreting work continues in both tunnels.
