And to think when I lived as a child at Buckfastleigh, Buckfast Abbey was better known for its honey than its wine.While out looking for some new mines, we came across the two names that put Lanarkshire on the map:

that looks nice!
This photo - showing a short gap between two sections of tunnel - reminds me of the railway in Mexico that goes close to the Copper Canyon. It runs from Los Mochis to Chihuahua, is 656km long, contains 37 bridges, 86 tunnels and took 60 years to build. There is a spiral tunnel - to gain/lose height - and at one point it comes out, immediately crosses a deep gorge and immediately plunges back into tunnel again. Impressive, just as is this photo. There seems to be another short gap at the far end here.One of my favourite photos from this year. Haddon Tunnel at the opening halfway through.

Thanks! That railway sounds really interesting. This is the only gap in the tunnel, the light you see through the photo is an air shaft, there are a few behind where the photo was taken too.This photo - showing a short gap between two sections of tunnel - reminds me of the railway in Mexico that goes close to the Copper Canyon.

In that case, it is a very wide air shaft. Do you know if it is visible above ground, in the form of a round wall about ten feet high? Too high for anyone to see over, or easily climb. There are many railway tunnels with a series of such shafts in a line. Often they were used to speed the excavation on several faces at a time; then left for the smoke from steam locomotives to escape.Thanks! That railway sounds really interesting.

The smaller air shafts are circular and are visible above ground, I believe there are bars around them from above so people don't fall into them. Here's a pic of one of the air shafts from inside the tunnel:In that case, it is a very wide air shaft. Do you know if it is visible above ground, in the form of a round wall about ten feet high?

The small diameter of this shaft marks it out as probably only to allow smoke from steam locos to escape, rather than one used for the extraction of material during the tunnel's excavation.

brick-lined size of the shaft - not the bare-rock size it was when dug, which would have been somewhat greater and thus possibly used for removing material from intermediate rock faces.
Very interesting information!Yeah there is 3 grated shafts I believe & the one central opening
I've just found this on Wikipedia:Very interesting information!
