I think carriage of freight by water is a romantic idea for the enthusiasts, but as has already been mentioned, you can't get beyond the original reason for the demise of canal freight and that is better efficiency on road or secondly rail. Rail cannot expand much more, without major investment in infrastructure, and in any case, passenger movements have the priority. In my view, it is more likely that we will see a reduction in goods transport. Currently, everything is being blamed on climate change, whether it is wet weather or the need for more taxation or higher energy or water bills. I believe that we are heading for extreme penalty taxation to reduce goods movement around the globe. Yes it will be done in the name of climate change, but is more likely to involve some national protectionism. Current political thinking will see more localised production.
