Some of the Cornish underlie shafts were low angle just because the lodes they sunk on were very low dip - eg on the Great Flat Lode & underlie shafts on the flat lodes around St Agnes. These would have used skips rather than normal tram waggons because the top parts usually went vertical, the only difference being the way the discharged & the design of guides. At Tywarnhayle (at one time managed by John Taylor & Sons) one underlie shaft still recently contained a double skip road really consisting of double tramroad tracks - difficult to say what ran on these. I am sure photos must exist of this (I possibly took one). The former RSM chap on site assured us on a visit that these were 19thC in date, but I am not sure about this & suspect they date from the early 20th C reopening. The Betsy & Friendship MRO sets definitely both included plans as well as sections. ________________________________ From: Robert Waterhouse <[log in to unmask]> To: [log in to unmask] Sent: Tue, 23 August, 2011 10:15:50 Subject: Re: Underground Inclines Dear Ali, I mean an angled shaft designed to take a railway, rather than a skip road as found on vertical or near-vertical shafts. One should be able to walk up and down without using ropes, though of course some are pretty steep even so. I went down the Wheal Crebor one with a rope at Rick Stewart's insistence, but didn't really need it, while Cononley is an easy scramble. I'm perfectly well aware that there are exceptions - one of the ones at Friendship shown on the long section is clearly sunk on a cross-course or slide as its only about 15-20 degrees off vertical, but it seems to be an exception rather than a rule. In reply to your previous email, I found the Friendship long section, looking north on the line of the principal lode, but have never seen a vertical plan of the workings. I have not seen either plans or sections of Betsy.

Taylor & Sons there were of course numerous examples, Botallack, sub inclines at Geevor & S. Crofty, Parc Mine, etc etc. Also I think you need to define what you mean by an incline - the vast majority of shafts in UK metal mines pre 20th-c were inclined rather than vertical, ie sunk at least in part following the dip of a lode.
