The 12 Days Of Viking Christmas: Going Through Locks, Will They Be Frozen?

A big part of the river cruise experience is locks.  Last summer, on our Portraits of Southern France itinerary with ,  we went through a bunch of them. Raising or lowering just one or several boats at a time, the , canals and waterways that make up the Danube’s navigation system.

The distinguishing feature of a lock is a fixed chamber in which the water level can be varied. We have been through a variety of different locks on our voyage as seen in this photo album.

Last year, a strike by the operators of the lock system brought disruption not only to river cruises but to the transport of freight as well. In Germany lock keepers conducted rolling strikes, which extended beyond the initial timeframe and resulted in some locks being temporarily closed.

The Altenwörth Lock in Austria was operating with one of two chambers open, which had the potential to cause a minor delay in sailing time depending on river traffic at the time a ship is passing through. For that reason, river cruises may arrive early or late at destinations.

A few Viking ships had their sailing schedules altered by the closure of locks during the strike as they did during times of high (or low) water levels.

In February 2012, that was indeed a concern as a “Russian winter” climate pattern kept Europe frozen as a strong Siberian anticyclone hovered over northern Russia and triggered intense cold and snow.

That is not happening right now so we should be good to go.

Two years ago, the Danube did freeze and its  freezing was just one of many severe winter events at the time.  Heavy snowfall blocked roads and stranded towns in central Italy. A train in Montenegro was stranded on the tracks for three days due to heavy snow. Even Venice’s famous canals froze, a rare feat.

But  2012’s cold streak was the worst in decades, said Jim Andrews, senior meteorologist at AccuWeather.com in a Scientific American report.
