Many years ago I was on holiday in the Moselle valley, western Germany, and I remember that snaking around the vineyards that covered the steep valley walls, were a network of small monorails. Clearly they are for industrial purposes only, but I wondered if anyone knew anything more about them, had any stories, or interesting pictures or videos? And are there others elsewhere? I haven't been able to find too much, but there is this video of a tourist guide(?) talking about them to tourists ( German mono rack wine cart train and tracks on steep Moselle River bank ), a high-speed video on Facebook, and a few pictures below that I've taken from here, and here, and there is a short bit of footage showing someone loading one here (so credit to those websites/photographers).
