It looks like bikes on my phone No, just water pumps to suck up the lock gate leakage. Interestingly they’ve cleared the gunge out of that bit so it’s a sort of well, then the bed rises up about 2 feet back to its crap-filled normal level!

Not sure if its the same on narrow locks but Grand Union locks have a "sump 'ole" just below the bottom gates before the stop plank groove irons so you can drain a lock and completely dry out everything by putting a pump in the sump. Thats once you had cleared the sump 'ole of all the crap and old windlasses and hazardous waste which had accumulated in there. I wouldn't be surprised if this sort of thing was a bit old fashioned these days of elfin safety.
Its a good design though.

The 1930's Nene locks have exactly the same setup, about a 1 1/2' x 1 1/2' x 1 1/2' sump at the tail of the lock just in front of the guillotine gate. A Genny has been running 24/7 keeping a submersible pump running abd draining away the small amount of water that is getting by the coffer dam they built to allow removal of the Vee Gates.

Which lock is that ? I went down the Nene en route to St Ives in the early 00s and some of the locks had mains power if I remember right. Lots were wound with a fixed handle for the guillotines and one I remember had been fitted with solar panels and a big battery bank but someone had stolen some of the solar and all of the batteries so it was back to hand wind. Seems a bit over the top to run a generator to power a pump to remove such small amounts of water but I suppose if a battery setup was fitted then someone would nick the batteries...

That's our lock at Titchmarsh, We are pretty isolated so it was easy pickings. It was only the solar array that went. The batteries and charging gear are housed in a big strong enclosure. The DC battery bank is charged via our generator, once bitten twice shy! Its a shame as there are several other sites were power is a non starter, solar would be the answer but a few are even more remote than us. The EA pay a very small contribution to our fuel bill. It is a huge waste of fuel for the contractors to leave their genny running to power a fairly small 110v sub pump. I'll try and follow Nick's example and get some pictures on Wednesday.

As I remember it the solar panels were up on top of the guillotine structure and whoever took them was unable to get them all. I thought the batteries had been taken as well from a green GRP cabinet by the lock. That might have been somewhere else.

I fear one of the additional problems with contractors rather than C&RT staff completing such work, is that the former will just fulfil the contract, whilst the latter may have done 'what was necessary' whilst the work was ongoing.

No, we are the only DC powered lock on the River, it took them years to remove the redundant angle frame from the top. The guillotines were easy enough to climb, we used to climb them to jump in! They have bolted loads of mesh panels to them now meaning you can't climb up the raised gate to get on top of the steelwork. This means kids now tombstone (and die) off disused railway bridges ATM it's handraulic again, chiefly while they fart about with the lock. The DC motor shit itself in the summer meaning a horrid stainless wheel was bolted in place while they scoured the land for a replacement.

I think the picture with what appears to be a brick road way on the canal bed is worthy of discussion by knowledgeable historians. I know nothing. Not quite sure what you mean. In the second photo, the bricks are bank side where you move the lock gates. In the third picture, the “road “ is planks of wood put there temporarily to allow plant to trundle along the canal bed without sinking into feet of slime! Riveting stuff, Nick.

nice photos, as others have said, if they do the same as other places they won't be removing anything. I hope someone will take the bikes out from below the lock in the first picture ! They may need the help from someone with a strong magnet to do that Peter.

Looks like bricks for some reason If it's any consolation it also looks like bricks on my crappy gen 1 MotoG phone - hence my block paving comment.

I've just been to Wigan and had time to have a quick look at the work on the top lock of the flight. Pound below... Fruit machine... New gates... New gear...

No dice with photos of a drained down Titchmarsh Lock I'm afraid, the buggers have refilled it and are getting close to finishing the programme of works.

He was making a funny based on the presence of the bracing bars whilst the gates are fitted.
Lovely looking bits of timber aren't they.
