I suspect this was more of a publicity stunt and intended to be something of an amusement park ride for the 2.8-mile stretch between Brighton and Rottingdean.

It should not have been overly difficult to build an overland route up the "steep climb that would be hard work for the little tram cars" (1:18) by running two trams at a time in opposite directions, one acting as a counterweight for the other, like the cablecars in San Francisco.
