So I live in Switzerland and there is lots of funiculars in my country. Most of those were built between 1890 and 1930, and for most of those the line is on the ground most of the time, there is bridges only where necessary, just like a regular train line.
The Moléson - Plan-Francey funicular is very particular in that not only it was built much more recently (in the late 1990s), but also the line is basically a huge bridge, the funicular never stands on the ground.
I think this is very weird and should have made the line much more expensive to build for no reason at all. Why is this line built on a giant bridge rather than on the ground with bridges only where necessary? Bridges would have made sense in order to make the line straighter (and thus shorter/faster), but the line is not even straigt anywhere !
