There has been lots posted on here about the Queensway tunnel and the ventilation shafts, but there's no harm in resurrecting old threads. The Woodside shaft is most impressive if you get up close. Although I can't now remember the details, I know it was built using one single brick of unusual dimensions (something like 10" x 3" x 2 1/2"), set in different orientations. I think Rowse did a great job on all aspects of the tunnel design.
This, of course, has nothing to do with the rail tunnel ventilation shaft mentioned in the market thread, which is about 40 years earlier.
The search function is not good on this site and I could not find a specific thread regarding the shaft so no harm in creating a new thread.
Regarding the market thread you are correct. The similar design threw me off with the one on Taylor st
I get a bit excited at times
Can't see these images. Pity. I'm sure they are interesting.
Excoriator, if you click on the link I posted and scroll down the page both pictures are there
The inside workings are fascinating and the design is something else
I often wonder why they are different than the liverpool side shafts
