Hi Rockoyster -
Let us suppose that they run the funicular up the hill 10 times per hour, which would be unusually frequent service.
Further, let us say that they have a very generous capacity per car....how about 100 people? That is also very generous.
If they run it 18 hours per day at that rate all day long, they would have 18,000 people. They would need about 36 boat trips per day, at 500 people per boat. Once per hour is the most likely ' High" number, and not all day long.
The roads up to Bürgenstock are not exactly superhighways, and, as presently configured, parking capacity is no more than a couple of hundred cars... considering both access routes. One trip per car per day could add 800 people. Lets go for 4 trips. Total 3200 people. Similar orders of magnitude for residents, but they would not be "visitors" and would have their own parking places.
Of course, they could build parking garages.........
Bus service currently goes to near Trogen; the map shows it is supposed to run all the way to the western parking lot, where it could easily find room to turn around. During construction, that access has not been available, but I assume it will be in use.
Two buses per hour with 50 people per bus would add 1200 to 1800 people per day.
Total with these generous assumptions- 20,600.
I'm betting with Lucas. Someone slipped a decimal point. Probably the number is 10,000, and that figure comes from biased sources.
And, some portion of that is not from the "super rich" class....it is people going to Hammetschwand for a sausage.
Just my opinion. ;-)
