  1. It falls outside the time period I suggested but in every other respect yes. I knew this lock well as a teenager, and I didn't know until recently why the old chamber was present.
  2. Bradshaw 1904 has the maximum beam as 14 feet 3 inches - I doubt the locks have got any wider!
  3. I've been through that but knew nothing of the history other than it was obviously substantially rebuilt, I'd agree it is a (very good) pastiche of the original locks on this length. I must have a closer look sometime
  4. Apologies for taking the thread off topic. It was certainly pre-1984 when they opened. Mum grew up in Appley Bridge, and her parents and her sister continued to live there after mum left and married dad. As a young child the locks were derelict and I would play in the dry pound between them. The top lock was full IIRC correctly. once I was a teenager (I turned 13 in 1979) we would take our boat out, launch it at Parbold and cruise up to Appley Bridge, after a while we would leave mum with her sister and her mother (my grandma) and dad and I would take the boat back, retrieve it and drive back to Appley Bridge to get mum. On one occasion to our delight we found the shallow locks in working order and went through them, we subsequently did this a few times, usually returning down the deep lock. I don't know why we stopped, things change, perhaps grandma was less well and it wasn't appropriate for Dad and I to gallivant, perhaps mum started visiting alone - I can't remember. I know it was pre-1984 because on the first trip (and possibly all of them) (a) I couldn't drive a car and ( b) I wasn't at university - both these changes happened in 1984.
  5. I don't know the answer but, as one of the few people to have used them, they were only half heartedly restored - no ground paddles for example. I think new gates were fitted, the canal dredged and then they stayed open until lack of maintenance closed them again.
  6. Easy, my original stance was that neither was on the list, and now neither is!
  7. That's Winston Churchill and his hippopotamus definition! Limehouse is used as part of an inland journey, by boats going west on the Thames from it or having come from the west. Tidal rivers are inland navigations within reason - my reasoning is ill defined but certainly includes inland from the connection with a non-tidal waterway, but also for want of a better description where they are cruising grounds in their own right - thus for example the Fal is an inland waterway. Some rivers with barrages were cruising grounds already, some have become such once non-tidal. I'm probably okay counting locks that mark the end of inland waterways (hence some of the river barrages) - so Brunswick might count on two grounds - it's the seaward end of the Liverpool Link and you can nip across the Mersey to the Manchester Ship Canal - that's a rather different crossing to the tidal Trent or the tidal Thames though. I really don't buy the Thames downstream of Lea Mouth as an inland waterway in it's own right, not do I buy Royal Albert Dock as an inland waterway - so that's out!
  8. I think both those are stretching the definition of Inland waterway, Royal Albert Dock is downstream of Lea Mouth and isn't an inland waterway in it's own right - Brunswick lock is more plausible although the Mersey-Eastham passage isn't as free and easy as the Limehouse-Teddington one
  9. Indeed, and I think autonomous barges have been trialled somewhere on the continent recently - I'll have to leaf through recent back issues of IWI to see if I can find it.
  10. I think Enigmatic has nailed it with their first two paragraphs. Automation is pointless - ours is primarily a leisure pursuit, we do it for fun.
  11. I fancy a pair of autonomous walking boots, they could walk up Snowdon and save me the trouble...
  12. It's arguable either way - none of the old structure survived but as you say the lock didn't move at all, on most rebuilds part of the old structure survives, often the invert - so it's a bit of a one-off. It's not really what I was looking for but it was a new structure. To describe what I was looking for is difficult, but roughly "locks built in the modern era to a traditional design using modern materials and techniques" - the main emphasis is "modern era", at least in part to compare with any locks that might be built in the near future - "here's one we did earlier" kind of thing Thurlwood steel lock is such a one off that you can't really categorise it. Edited - having re-read my original definition you're right.
  13. Hmmm - yes it should be in the list shouldn't it - it was, after all completely new!
  14. no error on your part, just on mine - now edited to add
  15. Here we go, latest revised list - I haven't included modified Locks or locks at coastal marinas Canal Restoration · Droitwich Juntion - 4 new locks as part of realignment for restoration (2011) · Ribble Link - 8 new locks on an entirely new navigation (2001) · Rochdale - Tuel Lane, one lock replacing two (2001?) · K&A - Bath Deep, two locks merged into one new one (1974 but unused until the 1980s) · Graham Palmer lock – Montgomery, (canal bed settlement) · Locks 2E, 3E (Twice) & 21E on the Huddersfield Narrow, all relocated in the restoration. lock 6W in Stalybridge also relocated. · Staveley Town Lock on The Chesterfield (vertical realignment of canal) · Dixons – Chesterfield – moved about 200 yards downstream on restoration · Boundary Lock on The Chesterfield (settlement/subsidence) · Loxwood Lock on the Wey and Arun, which replaced most of the fall at Brewhurst Lock (road crossing lowered) · Prince's Dock Lock and Mann Island Lock No 6 on the Liverpool Link · Moira on the Ashby Canal (Subsidence) · Locks 1, 2, 2a, 3, 5 and 11 on the Forth and Clyde.

  16. Now that would be quite a restoration project! Do we know to what extent these were navigated? Given the low lying land I guess quite a lot
  17. A lot of good stuff - in the next day or two I shall revise the list with most of the extras On reflection, tidal barrages that create an inland non-tidal navigation count (at first I took the view they didn't), so Tees Barrage, Swansea, Cardiff etc - locks on tidal marinas don't, because these aren't an inland navigation, and also because I suspect there are a lot, probably not related in any way to inland navigation. Tidal river barrage locks are therefore an interesting subset. I think the Nene locks that have simply lost their guillotine gates were partly rebuilt rather than entirely new locks,but I do acknowledge that others were relocated. Hulme Lock was simply extra wall, rather like Anthony on the Rochdale, albeit with rather more extra wall! I had several reasons for not going back before WW2 - one of which was the large number built in the 1930s - these are worth a seperate section all to themselves. I'm primarily a historian, so time periods interest me, and I'm interested in this case in locks of the second half of the 20th Century and early 21st as that's a relatively homogeneous time period in waterway history. Thanks I I think Ireland needs a category all to itself - they do things different over there! Some of my Irish friends have noted this is the first new manual lock on the island of Ireland for many decades, other new ones have been mechanised, I haven't checked yet whether this is true, but it sounds plausible. List for post war British Mainland to follow when I get round to it!
  18. Thread Locked - this has gone beyond debate, discussion or even argument and descended into a slanging match We do not have rules over how to enter into debate other than basic civil behaviour - some of you are not displaying that. The original poster made a valid point about entering a lock that had wildfowl in it, this could have been debated and some people tried, for others a red mist descended. Red mists get threads locked and may get warning points. Be aware we do not identify on the forum any action we take against specific individuals, so when you ask "why did they get away with it" they may not have done. If foul or abusive language is pointed out to us we act.
  19. Lutine's bulkheads could easily have dropped like that as they only reached the cabin floor not the base plate - through bilge. In Lutine's case the cabin moving significantly would certainly have caused it - GRP cabin on a steel hull.
  20. Indeed - sloppy English on my part, a deeper lock was built alongside and then the old one closed.
  21. No - just within it! Go down, get under the bridge, go up again. Early designs for this type of lock had a short pound under the bridge - in effect back to back locks. The intervening pound didn't survive the design process - not safe and not necessary.
  22. Not convinced they're new - I think they are built on the original structure. It gets messy deciding what is new - Bath deep is in the same location as the original lock 9, but is twice the fall as lock 8 below it was removed. On the other hand the lock on the Rochdale that @David Mack identified has simply had it's walls raised - Bath deep is new, I'm not sure the Rochdale one is. Tuel Lane and the one in Tinsley are not on original lock locations. Tinsley has moved sideways and Tuel Lane, curiously, is between the two locks it replaces
  23. Kegworth Deep was deepened and all the lock down to Redhill replaced, Redhill had it's cill lowered, but I've no idea how many intervening locks there are Edited to add - well spotted that I missed it off, I hadn't intended to Another good one for the list - thank you
