OK, yes, that was a generalisation. Almost all canals on the used 
sections of recreational canal on the map I gave a link to have 
towpaths. The vast majority of canals have towpaths.

Every lock has more than one gate - at minimum, they have a top gate and 
a bottom gate, and some have two of each. A simple staircase lock has 
two chambers and three gates.
