tree monkey Posted July 14, 2019 Report Share Posted July 14, 2019 This lock has caused some, errr discussion between myself and the lovely BSP. It's a water saving thing and not a staircase. Link to comment Share on other sites More sharing options...

Jen-in-Wellies Posted July 14, 2019 Report Share Posted July 14, 2019 (edited) Several locks on the S Yorkshire Navigation have this feature. An intermediate set of gates for 60', or so size Humber Keel boats and outer gates for longer ones. Only Bramwith lock have I seen them in regular use and this is the only one which isn't power operated. Caused me some confusion the first time as approaching from the low side I could see what looked like an empty lock, with the gates open, when in fact two boats were coming down the short lock section. Some pictures on the Pennine Wateways site. Jen Edited July 14, 2019 by Jen-in-Wellies 2 Link to comment Share on other sites More sharing options...

Not only does keeper date it, so does coal train and Ferrybridge! Can't remember if Bulholme still has the second set of gates. They may have gone as, being fed from the Aire, there isn't a need for water conservation Jen Link to comment Share on other sites More sharing options...
Dave123 Posted July 15, 2019 Report Share Posted July 15, 2019 Interesting lock! I think Cookham lock on the Thames has the same kind of duplicate gates but never seen them working... Link to comment Share on other sites More sharing options...
Scholar Gypsy Posted July 15, 2019 Report Share Posted July 15, 2019 Also Cromwell lock on the Trent, West India Dock, and the first lock on the river Wey (I think that one is to get deep draughted boats over the intermediate cill). Link to comment Share on other sites More sharing options...

It's a water saving thing and not a staircase. What is unusual is that this lock is very short and the gates are roughly half way - they can (and do) use either half as all visiting boats are less than 35 feet long It's also wide beam, although the Ashby (of which it is part) is regarded as a narrow canal these days - when we looked at the costings the costs of building everything to wide beam was not that much greater and the canal was originally proposed to be wide beam (and was built lock free!!!) All in all a contender for the most curios lock in the country Link to comment Share on other sites More sharing options...

This is me penning down through Bulholme about 18 months ago. Not 100 percent but don't think it still has the second set of gates. Read somewhere about this lock being surveyed with a view to increasing its dimensions. Link to comment Share on other sites More sharing options...
Pluto Posted July 15, 2019 Report Share Posted July 15, 2019 This drawing by a BW engineer circa 1950 shows the phases in the elongation of Bulholme Lock. There were similar phases for all the A&CN locks. Link to comment Share on other sites More sharing options...

Here's the inner end of it. Made all the more curious by it's gradual evolution - at one time it was just a sluice at the entrance from the Trent (and before that, two pairs of gates at Misterton Soss) Okay, the challenge is on for locks that are a bit different, out of the ordinary or downright odd - any more contenders? So Far Moira - (1) on a length of restored canal that didn't originally have locks (2) wide beam on a narrow canal (3) only 70 foot long with intermediate gates half way along (rather than the more usual two pairs of bottom gates) Stockwith (Idle) (1) 1000 feet long (2) Turf sided and not exactly straight (3) an unintended consequence of water control function.

I can lay my hands on a Tabur Yak II for you - but having seen what happens when they draw the paddles I'd suggest you go down rather than up!
