[Germany]North-South Mainline near Rastatt blocked...

Postby Motorman » Sat Aug 12, 2017 4:42 pm

A mishap during tunneling works has blocked the Mainline south of Rastatt for an (until now) undefined duration.
Chaos is here. :(
Here are some pics: https://www.drehscheibe-online.de/foren ... sg-8269239
And here it is: https://www.google.de/maps/@48.8449773, ... a=!3m1!1e3
As some of the potential detours are closed for routine maintenance, it will be a nightmare to get trains running in schedule again.
Latest news say, it may take at least one week to solve the problem...

It looks like a sinkhole or a culvert collapsed.

They were boring a tunnel underneath. Due to heavy water flux there was a landslide inside the tunnel construction site, which collapsed the surface above.

The whole section where the tunnel crosses the existing line was under permanent surveillance using a laser grid for exactly that kind of thing, hence preventing any accidents.

Update:
Officials say, that the "tunnel" will be filled with concrete and the tunnel boring machine will be abandoned.
There were more slides in the last hours, so waiting for an "idea" is not an option.
When the conrete-plug is finished, the railroadbed will be renewed, temporary.
This sounds weird, but this is much cheaper than an undefined lockup.
The traffic is already in chaos, as there are no suitable detours possible.

Hehe, when we Germans make mistakes, they're perfect in any way. :-D :wink:

There were some rumours that they were using an experimental stabilization method for the construction, to be exact pumping cooling agents through pipes in the tunnel walls leading to the surrounding ground being iced solid.

Any truth to that?
