In 1957, the partners came up with the idea for a lift — customers had been asking for one for years — and hired Oakland’s Dwan Elevator Co. to install the red inclined “hillavator” that could carry six guests at a time 118 feet to the entrance.

So, yep, definitely an elevator. But even elevators use a counterweight, which in a Funicular is another car, and it's along an incline.

Hmm, so is there really a difference?
