That will be interesting to watch--I hope they set up some webcams like they did for the Landwasser work. All that rock has to go somewhere! :)

The Hotel Grischuna said they expect a 24/7 spoil working service, it is possible that the Ge4/4I's will be used on this project.

I got the impression last visit that some work had already been done on the north portal area at Preda. The sidings there have also had a makeover.

Don't know if I'd want a room in the hotel if the trains are going by 24/7....

:)) Yes there are times when one can experience too many trains!

I'm curious where they will take all the rock from the tunnel excavation for processing. I'm guessing that Preda is at the low side so it would come out from there to a large property nearby or maybe near Berguen where they would set up the crushing plant and cement plant. It will sure be an interesting project to watch! :)

Maybe by the time they get started on the project our Cdn dollar will gain a little back compared to the Swiss Franc...right now it's cost prohibitive. :(

"Too many trains" only applies if one is stuck at a level crossing. Everything else is WOW!

I think I read somewhere that they may use it to fill in that gap called the...what is it now :-? ... oh, yes, the Landwasser..something :-? ...yeah, the maintenance on that viaduct is crazy! ;)

I wonder if they'll use the same yellow cars they did for the Vereina tunnel.

Nachhaltige Bauweise
Die Erschliessung der abgelegenen Baustelle erfolgt zu einem Grossteil per Bahn, wofür auf beiden Seiten des Tunnels je ein Baubahnhof erstellt wird. In den Portalbereichen werden in der Bauphase vorübergehend grössere Flächen belegt. Das anfallende Ausbruchmaterial dient als Rohstoff für die Beton- und Schotterproduktion und wird in Preda aufbereitet. Für Material ungenügender Qualität wurde im Gebiet «Las Piazzettas» bei Preda eine geeignete Geländekammer zur Ablagerung von bis zu 250 000 m³ Ausbruchmaterial gefunden.

From the RhB website - I think it reads that the spoil will be processed at or around Preda

^suitable stuff will be converted for use as gravel or in a concrete mix at Preda, other (up to 250,000 cubic metres) stuff will be dumped at Las Piazzettas near Preda travelling from the tunnel workings by conveyor belt..
This is located north of Preda, as you leave the station heading for Chur it is on the right about where the sledge run starts.

Neat--thanks Paul. Looks like they are re-routing some electrical duct banks. This is going to be an interesting time watching that construction--lots of good modelling opportunities coming up! :)

Does anybody know what kind of rock the cliffs at the Landwasser viaduct are, and the geology of that region? Is it Dolomitic limestone? (that's what the actual viaduct is made of...)
Thanks.

They quarried the stone more or less on location and built a "very narrow gauge" track (500m ??) to transport the lime stone material to the building site.

Thanks. That helps.
