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.

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.

Going beyond your remit of J. 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.
