At one time, avocados from high up the steep fruited slope of Mt. Ararat were brought down to trucks via this rail car, which ran on a single track.
In our shed there is an old motor, and around the grove there are several old bins that would have been placed on this car.
The second photo shows the line from farther up, above LF HQ, the house, and the valley so low (note the banana grove, before the freeze, just above HQ). Alas, the line is not functional. I have always fancied the idea of making it work and planting the highest part of the slope and using this line to get me and materials up the hill. However, it would be costly–and probably not very safe.
I have had a few people come by the finca who have been associated with the avocado business for many years and they usually say they have heard of these devices being used in the area, but are not aware of any other tracks still in place, let alone working systems.
Of course, in some other parts of the world, one can find working systems similar to this–for instance in some Italian vineyards.
