In Britain there have been various types of boat lift. One type
involved small ("tub") boats fitted with wheels, which were hauled up
or down slopes on rails and then launched into the higher or lower
canal pound at the end of the lift.
Another approach ("compartment boats") was to have craft that could be
towed in trains, and then lifted individually on to specially-designed
rail vehicles to get to the individual mines.
Waterway transport generally uses less energy and labour per tonne-km
so (other things being equal) it can pay to transfer the load from
rail to water.
