the Volk's electric railway runs between the Aquarium and Black rock via Halfway station with 6 cars in use in the present day 2 single trains 2 double trains
Interesting as the oldest operating electric railway in the world but there's not a lot to it. It's barely a mile long IIRC, slow with no variation at all. If it could be presented in its 1890's form and tied in with Volk's other enterprise the Brighton to Rottingdean "Daddy's-Long-Legs" you might be on to something.
I don't know if you have been on the line - it is just over 1 mile long. What do you do after your 1 mile trip?
