Funiculars and stations you can place on slopes.
Funiculars are missing entirely. One is like a tram, the other is like a ski lift.
Blimps or dirigibles.
aquatic attractions, like: coral reefs, blue holes, capsized ships, grounded ships.
large equipment factories, like: airplane assembly plant, shipyard, construction and excavation machinery assembly plants.
They would consume goods like an auto factory, but not actually give you anything you can transport. At least, not unless there was another good added.
Oversized goods and specialized vehicles to carry them. things like small ships, airplane wings and fuselage, electricity transformers, gas tanks, cranes, or heavy construction equipment.
specialized vehicles can be like: schnabel car for rail and road or airbus beluga.
motorbikes and scooters. low capacity and low maintenance, but not unusual to see them used for deliveries or as a taxi when sidecar is added.
