There was a Cablecar here that run from 1932-1972 with Watertanks as a balast. If the "cabin" was too haevy, a pair of wheels would touch the ground and drain some of the water to reduce its speed when approaching the station.<br><br>Sometimes I wonder about the "simplicity" in modern designs, as back then, they couldn't do "complicated".  It's almost a lost Art.
