Going Through the Lock System

I know I keep talking about going through the locks, however these are important as they control the flooding of the rivers and also allow boats to go uphill! All the ones so far had us going down with the water, but now we are in the Danube Canal connecting the two rivers, part of those locks have the water coming in and we are rising 20-30 metres (thats a lot for the uninitiated!) It was late one night (10.30pm - the lovely oldies had to stay up past their bed time) and we encountered our first one of these. We were allowed outside (a no-no when going through locks cause the walls are about 10centimetres away each side!)up on the top and took photos! it was a wonderful experience because you started out with these towering walls up each side of you, and then suddenly start rising up quickly! the big discussion was the gate, did it go up?, sideways? split open in two? swing back on one side? big debates by all these amateur engineers - i said swing back, dave said slide sideways .... well ..... guess what! it went down! under the water! It needed a few metres clearance underneath for the boat to go over the top! all operated by two men at the computer back in Nuremberg or somewhere hundreds of miles away. I hope you can see cause it is at night!
