The dates are guesses, based on the construction of the Kowloon-Canton railway line.
The location is also a guess. We know there was a ropeway built here to ferry workers from their camp to the Beacon Hill tunnel, but I'm not sure of the location of the camp or the route of the ropeway. Suggestions welcome!
Here are the couple of mentions I've found:
- A further 850m-long cableway was also built about 1907 to transport foremen and miners, at that time constructing the Kowloon-Canton Railway Beacon Hill tunnel, to bungalows on a hill the other side of the valley from the north portal (most probably at Sha Tin Heights).

- On a doctor's advice, all the Italians working on the Beacon Hill tunnel were housed high up on the hillsides and a ropeway was built to slide them gently down to work each day.
