Harecastle Tunnel

After a final walk around the lake with Dudley we set off just after 9am for our short trip to the tunnel. When we arrived the tunnel keeper said it would be about an hour wait as there were still a few boats going through our way and once they were through we had to wait for the ones coming from the other end. It was perfect for us as we were able to fill up with water whilst we waited. Sandra on Golden Boyz wasn't far behind.

We had quite a wait for the boats coming through, there were eight of them and the tunnel keeper closed the doors two or three times between them as they were about ten minutes apart. Finally it was our turn, Sandra preferred to go first then we followed on with another behind us. When we got to the other end we could see Sandra had stopped and wasn't exiting the tunnel, the keeper at that end hadn't lifted the barrier and she had nearly crashed into it. The people waiting at the other end apparently were shouting across to him that the boats were waiting to come out. He had been having a quick lunch break in his van.

Dudley can make it to the front without the roof boxes on

Then it was down through a few locks before stopping at Church Lawton. I walked back up and helped Sandra down the last couple.

Info on Harecastle Tunnel taken from Wikipedia
Harecastle Tunnel is on the Trent and Mersey Canal at Kidsgrove in Staffordshire. It is made up of two separate, parallel, tunnels describe as Brindley (2,880 yards or 2,633 metres) and the later Telford (2,926 yards or 2,675 metres) after the engineers that constructed them. Today only the Telford Tunnel is navigable. The tunnel is only wide enough to carry traffic in one direction at a time and boats are sent through in groups, alternating northbound and southbound. Ventilation is handled by a large fan at the south portal. 

Brindley Tunnel
The Brindley tunnel was constructed by James Brindley between 1770 and 1777. Brindley died during its construction. At the time of its construction it was one of the two longest canal tunnels in Britain, together with Norwood tunnel its twin Brindley bore on the Chesterfield Canal.

The tunnel had no towpath, so boatmen had to leg their way through, lying on the roof of their boat and pushing on the sides of the tunnel with their feet. It could take up to three hours to get through the tunnel. The boat horses were led over Harecastle Hill via Boathorse Road. A lodge (Bourne Cottage) was built by the side of the squire's drive at the point that the boat children crossed it to prevent them straying up towards Clough Hall. To construct the canal, the line of the tunnel was ranged over the hill and then fifteen vertical shafts were sunk into the ground. It was from these that heads were driven on the canal line. A major problem was the change in the rock type which ranged from soft earth to Millstone Grit. The construction site was also subject to flooding regularly, a problem which was overcome by the contruction of steam engines to operate the pumps. Stoves were installed at the bottom of the upcast pipes to overcome the problem of ventilation.

The tunnel was twelve feet tall at its tallest point and was nine feet wide at its widest, which proved to be too small in later years. The tunnel suffered subsidence in the early 20th Century and was closed after a partial collapse in 1914. Inspections of the disused tunnel continued until the 1960's but since that time there has been no attempt to investigate the interior of the tunnel at any significant distance from the portals.

The gated portals can still be seen from the canal, although it is no longer possible to approach the mouth of the tunnel in a boat.

In recent times water entering the canal from the Brindley tunnel has been blamed for much of the prominent iron ore (responsible for the rusty colour of the water) in the canal, and there are proposals to install filtering (possibly using reed beds) at the northern portal.

Telford Tunnel
Due to the amount of the traffic and the slow process of legging the Harecastle Tunnel was becoming a major bottleneck on the canal. It was decided to commission a second tunnel to be built by Thomas Telford. Due to the advances in engineering it took just three years to build and was completed in 1827. It had a towpath so that horses could pull the boats through. After its construction it was used in conjunction with the Brindley tunnel, with each tunnel taking traffic in opposite directions.

Between 1914 and 1954 an electric tug was used to pull boats through the tunnel. In 1954 a large fan was constructed at the south portal. While all the boats are within the tunnel an airtight door is shut and all the air is pulled through by the fan. This allows diesel boats to use the tunnel without suffocating the boaters. Today the journey takes about 30-40 minutres.

In the late 20th Century the Telford tunnel also began to suffer subsidence and was closed between 1973 and 1977. The towpath, long disused, was removed allowing boats to take advantage of the greater air draft in the centre.

A series of small canal tunnels are joined to the Telford tunnel. These tunnels connected to coal mines at Golden Hill and allowed both the drainage of the mines and the export of coal directly fro the mines to the canal tunnel without the necessity of first hauling it to the surface. Small boats of ten tons' capacity were used in this endeavour.

Kidsgrove to Stone

Sunday saw us leaving our Kidsgrove mooring crossing the aqueduct over the Trent and Mersey Canal, which apparently is one of only three such aqueducts in Britain. I'm guessing the other two must be the ones on the BCN, we passed over and under the one on the Birmingham Level Mainline and the Wolverhampton Level Mainline, and the other on the Engine Arm going over the the Birmingham Level Mainline.  

Macclesfield Canal over the Trent and Mersey

We turned a sharp left bend and ran parallel to the Trent and Mersey for about 600 yards, as that rose through two locks two meet the Macclesfield level, where we had another left hand bend, under the bridge and at the junction we turned right heading for 'the' tunnel. Just before the railway bridge was the queue where the tunnel keeper was and he informed us we were boat number eight, which was lucky as they only allow eight boats through at once, three other boats arrived after us to join the queue. It wasn't long before the five boats coming the other way passed by and we were on our way last in the convoy, the tunnel keeper had told us this was the best position heading south as the extractors were at the other end drawing all the fumes away so we should have a clear passage.

And out again in the sunshine, looking back

It took us just over 50 minutes to get through and at a couple of places it was really low. Once out, squinting in the bright sun, it was just as busy the other side with about 12 boats waiting to go through, some of them were going to have a wait of about two hours.

There are three tunnels through Harecastle Hill with only one remaining in use. The first was completed in 1777 and took 11 years, it was 9ft wide and one and three quarter miles long, there was no towpath and boats had to be legged through, as it was slow going it become a major bottle neck with huge queues and long waiting times, and in those days 'time was money', so a second tunnel was constructed in 1827 and took three years to complete, this time there was a towpath, but due to subsidence resulting in it being more than a foot under water in places, it was removed. Each tunnel become one way until 1918 when the original tunnel bore had sunk too much from mining subsidence. The third tunnel was a railway tunnel and runs 40ft above the canal tunnels, this was closed in 1960 and the railway now goes round the hill and through a much shorter tunnel.

We continued on to Etruria, where we moored near Festival Park for Morrisons which was a walk through the lovely wooded park to a massive retail park. We got the solar panels back on the roof which kept the batteries happy in the nice sunshine.

6 miles

Moored near Festival Park

Tuesday we set off through through the Stoke lock flight, which is made up of five locks and a drop of 50ft. At the top lock we met a hire boat just entering the lock, there are anti-vandal locks here, unfortunately they dropped their key into the water, I worked the lock for them as they attempted to get it back with a large magnet borrowed from the CRT maintenance yard next to the lock. We got LJ through the lock and left the hire crew still fishing for their key, hope they were successful.

I spotted this building along the road look over from the second lock

We carried on through Stoke-on-Trent and past the Stoke City football ground, which we could just see through the trees, then through Trentham lock with a drop of 11'11", past the Wedgwood factory and moored in a nice open stretch near Barlaston.

5.25 miles and 6 locks

Moored at Barlaston

Yesterday we set off just after lunch, after all the rain had passed by and were soon at Meaford Locks, where there are four locks with a total drop of 32'5". It was good going through these locks, with one in front and one behind us and passing a hire boat from Mercia Marina with a lovely couple and their daughter along with two dogs, which were in disgrace as they had rolled in something nasty.

We carried on for a little while longer and moored up a couple of hundred yards from Lime Kiln Lock, just before Stone.

3.75 miles and 4 locks

Moored near Stone

We had a wander into Stone to suss out where the train station was so we knew where to go to meet our visitor on Wednesday. We found the great chippy and as time was getting on treated ourselves, would definitely recommend it, on our stroll back to LJ we passed by a Pub Boat and then found a shortcut to the station!
