Hot

Thursday 28th May

Whilst this was the hottest working day for the Drainage team so far this year, thankfully the day time maximum for Winchcombe (30C) was reached mid afternoon, whilst we were enjoying a cup of tea in the shade back at Winchcombe station. Also, thankfully, it was not quite as hot as over the Bank Holiday Gala weekend (maximum 33C on Monday afternoon).

Ten of the team attending – with breaks compulsory, not voluntarily, and consumption of water rather than coffee.

Jonathan and Dave first headed to Honeybourne to collect some more bags of postcrete from Fairview Building supplies. This took a little longer than intended due to road closures near Willersey.

The other eight, Stuart, Martin (S), Martin (J), Nigel, Polly, Roger, Peter and Andrew, headed to the now repaired slip site between Gotherington and Bishops Cleeve.

Polly and Nigel worked on more bricking to raise the height of the final outlet chamber of cross drain 37D. Peter and Martin (S) inserted bolts to secure the grill on the inlet headwall of the exit bore of 37D – a job that has been on our to do for a long time. Stuart excavated a hole for the foundation base of the extended headwall which will take the exit of the new pipe in the slip infill area into the outlet ditch of 37D. Roger headed a little further south to de-rust and then paint with black MIO the bridge rail uprights of mile posts 16½ and 16¾. Andrew and Martin (J) started on the clearance of the down (Cotswold) side toe ditch back from the foot crossing to cross drain 37C.

After the first break for drinks, and to admire loco 78022 on the first southbound train, a bit of a swap around. Peter and Martin (S) joined the toe ditch clearing, whilst Nigel and Stuart mixed and laid the concrete for the extended headwall base. Polly finished the bricking of 37D exit and then cut the blue mesh GRP lid to fit snugly.

When Jonathan and Dave arrived, the set too to install another replacement section of fence alongside the footpath on the up (Malvern) side of the foot crossing. This was to make the section alongside the now cleared exit ditch of 37C a lot safer.

After the lunch break we tacked a few more odd jobs. These included a trim around the exit chamber of 37C and the installation of posts for badger monitoring on the up side near milepost 16½. The Gotherington badgers seem to have taken up residence there.

Wildlife report: There is an abundance of wild flowers along the embankment and in the boundary hedges are in full flower. Most noticeable are the daisies; we also spotted poppies and wild roses. Plenty of bird life today: blackbirds, robins, chiffchaffs, skylarks, pheasants, gulls, kestrels and red kytes. Whilst in the cooler and slight damper conditions in the toe ditches we spotted several centipedes, or perhaps they were millipedes. We were not able to correctly count the number of legs.

Wild (or dog) roses in the boundary hedge. We had to trim this bush to remove the dead wood that was obstructing the toe ditch beneath. Dead rose wood is tough!

Not so famous five

Thursday 21^st May

Just five of the team attending today – Polly, Martin (S), Martin (J), Jonathan and Andrew. All were working at the now repaired slip site between Gotherington and Bishops Cleeve.

Despite the small size of the team, we accomplished quite a number of tasks.

Polly worked on raising the final exit chamber of cross drain 37D. This involved a change of plan. We were originally going to use concrete blocks. However, those we earmarked had disappeared from Winchcombe Yard over the last week. So instead we used some reclaimed imperial bricks. The chamber needs raising here as the slip repair has raised the level of the ground. Also on the bricking tasks was the repair to the coping of the headwalls at either end of the 37D outlet ditch. We installed some marker posts by the inlet headwall of the exit bore – no excuse for hitting this with robot flails or other machinery now.

Martin (J) and Martin (S) completed the clearing of the down (Cotswold) side toe ditch which runs back from the 37D inlet to the foot crossing. This enables us to closely monitor any build up of water here; and to check the inlet to the pipe that runs under the foot path to the crossing.

Martin (S) racking out the down side toe ditch.

In the other direction Martin (J) doing the same, before getting the hedge trimmer to complete the clearance up to the foot crossing.

On the other side (up or Malvern), Jonathan and Andrew completed clearing the outlet ditch of cross drain 37C. This is outside the railway boundary, this work was undertaken with the land owner’s permission. Some high spots in the ditch were removed; so we should not now get any pooling water in the wetter months. Also we now can fully examine the discharge end of the 37C outlet pipe.

Jonathan works on the 37C outlet ditch.

An interesting discovery was a small brick structure; just two bricks wide mostly buried in the railway side bank of the ditch. Further digging and demolition revealed this was a small headwall on the end of a length of small diameter SGP pipe. There was a metal clip embedded in the end of the pipe. The depth, location and orientation of the pipe does not suggest an embankment toe drain. So this is a bit of a puzzle. As we removed a telegraph pole stay from the ditch, it may have some connection with that.

... and after, revealing the end of the SGP pipe with a metal clip.

Finally we installed another replacement fence post on the up side of the footpath by the crossing.

Wildlife report: We had a continuous serenade from Chiffchaffs in the hedges – not the most melodic birdsong. On our way back near Manor Lane we spotted some yellow hammers. The adjacent field on the down side was aglow with buttercups, whilst along the top of the embankment there are lots of tall white daisies. By the footpath we noted Ocimum basilicum, which has many common names – Common basil, Great Basil, Sweet basil, Saint-joseph's-wort. Green shots are appearing in the top soil covered areas of the slip repair, but nothing as yet in the compacted stone sections.

Basil!

Thursday 14^th May

A decidedly chilly day, the temperature being more like March than May. Luckily we managed to avoid all the heavy showers.

The ten team members in attendance split into two groups.

Roger, Stuart and Martin (J) first headed to the filled in bridge 41 between Two Hedges Road and Kayte Lane. The task was to put a second coat of paint on the safety marker railings, the ones made from old steam loco boiler tubes.

On the way back to the access at Pecked Lane, then check on the infamous ‘Bonsai World’ down side crest inlet. The stream was not running – so if it stays that way we might be able to undertake a good internal inspection of the circular manhole next week.

Where we suspect the manhole is leaking is around the exit pipe. [Photo by Martin (J)]

Then it was on to Manor Lane, to fit the new head for milepost 16. Finally back to Winchcombe to progress the manufacture of new milepost heads; they completed that for 15¾ and commenced on another destined for the Laverton to Broadway section.

Meanwhile, the group of seven, Jonathan, Dave, Polly, Martin (S), Peter, Ian and Andrew, made their way to the site of the now repaired slip by the foot crossing between Gotherington and Bishops Cleeve. (See the Gotherington Slip Repairs - Week 4 post on the Civil Engineering blog). The tasks here were to repair the fence by the footpath on the up (Malvern) side of the line. Dave and Ian cleared the brambles from around the old fence. Jonathan operated the auger this week to drill out four new post holes. Only one stone and a few roots were encountered, so the auger behaved much better than last week. Polly took charge of the woodwork repair and the installation of the new posts.

Repaired fence - apart from one missing new post. That is on the list for next week.

Peter and Martin (S) used the drain rods to ensure that the bore of cross drain 37D was clear – this tends to get obstructed with straw and other animal bedding it does not carry a great deal of water in the summer. Dave and Ian brush cut the ditch leading to the outlet chamber. All four then combined to clear out the outlet chamber and the short bore leading to it. An attempt to rod the pipe which runs under the boundary fence meat with solid resistance after a foot or so. Taking a photo with a phone revealed why. There is a small grill here where the exit pipe abuts a smaller diameter field drain in the adjoining land. We will have to ensure that this is regularly checked for obstructions.

As part of the slip repair, our contractors have installed two new 150mm perforated twin wall pipes which drain the embankment into the outlet ditch of 37D. We are going to install a small new headwall to protect the downstream end of these, so Andrew measured up the dimensions. Also measured was the exit chamber of 37D, as this now requires raising by two block courses. The repair has altered the profile of the up side embankment, so our plan to install a piped toe ditch now looks to be unnecessary,. So aided by Martin (S) and Peter, Andrew also investigated the possibility of installing French drains or transverse pipes instead.

After lunch, Jonathan and Polly undertook some clearance of the ditch that takes the outflow of cross drain 37C. This is outside of our boundary, so the work was with permission of the landowner. This removed quite a sizeable obstruction, we have often noted pooling water here during the wetter months. The others turned their attention to the low mileage down (Cotswold) side toe ditch that leads to cross drain 37D. As this was last fully cleared a few years ago, this was a significant task. With the exception of a tree that will require chain sawing, they managed to clear about three quarters of the length back to the foot crossing.

The tree that will need removing. Peter and Dave busy clearing beyond it.

Wildlife report: Plenty of bird life at Gotherington. Today we noted, robins, black birds, gulls, chiffchaffs, great tits, long tail tits, magpies and pheasants. Also heard, were skylarks. At lunchtime a kestrel hovered low over our work site, seeking out any rodents. On our way back we spotted a couple of squirrels. From a vegetation point of view, it is going to be interesting to observe how quickly nature covers over the slip repair site.

There she blows!

Thursday 7th May

Today, six of the team reported for duty on a warm, sunny day.

A big treat at lunchtime was the sight of Stanway Fountain being powered up - such a fine sight!  We all met up at the new drainage system at the top of the embankment at the Stowe Road. over-bridge at Toddington, hence the view of Stanway.  Fencing in the system was the aim of the day and this meant nine upright posts and four (GWR style) horizontal bars screwed to the posts.  Polly was our expert alignment operative, with his extensive building experience and his insistence upon all things being in line and square.

Jonathan and Dave were dispatched to collect the Postcrete from our supplier at Honeybourne (and enjoying a JT-inspired café stop on the way back).  The rest of us followed Polly’s lead and set out the post positions.  Ian was PIC, (Person in Charge) and therefore takes the blame for any cock-ups discovered later.  One-armed Martin was protecting his still-poorly wrist and was keen that Ian should not go the way of his injury while he manfully operated the new petrol-powered augur.  His cries of “Ouch!” And “This thing is violent!” were met by team member Peter with suggestions of him being glad that he was not on the “driving” end!   It was clear that a pilot hole dug by hand made life easier for the “augurist”, so Martin, Peter and Dave set to.  This improved life for the muppet operating the augur, with extra hands occasionally applied.

Holes dug, post were set in and checked for alignment so then water and Postcrete could be thrown in the hole, Polly’s magic spirit level satisfied us that posts were upright and within a very short time were securely in place.  While Ian and Martin worked to measure and cut the horizontals, the rest of the team secured them to the posts and thereby enclosed the new pair of chambers within railway property.  Both chambers were completed and covered, so now we await a real downpour to see if the solution we have implemented really does handle the flooding for which this location is renowned.  We hope that the neighbours in the railway cottages opposite would benefit from our work, but this remains to be seen.  Talking of neighbours, having Jonathan on the team regularly ensures that our relationship with them is eased and working at this entrance of a farmer’s field was no exception.  We were observed, but not interrupted or prevented from using the entrance for parking and material storage.

The resulting enclosed space now looks like GWR fencing, with a neat removable set of bars to allow the egress of the robot flail and the parking of its delivery vehicle safely off the main road.  The passengers will, as usual, be unaware that the new drainage system is even there,  Merely the absence of a flood up top and the sight of water draining into our downside cess would show success and something only the observant would appreciate.  Much of our work falls into this category of absolutely necessary, but rarely seen.  It is unlikely that the television cameras due to film our line in a couple of weeks will show any more than an inspection chamber cover.  However, we know and the permanent way above, below and alongside our culverts will be more permanent for our efforts.  Our workplace is a free gymnasium for all the team and indeed a temple for some.  Not bad value at all.

Wildlife report: Do sheep count?  Plenty were observed in the field and a deer was seen cantering across the field of verdant grass/. The team encouraged it not to clear the face and cross the road.  Much birdsong surrounded us, with wrens, blackbirds and robins all having their say.  The passing of Betton Grange and the Bubble car showed plenty of wildlife at table.

Off with their heads!

Thursday 30^th April

Another working day when we had multiple groups working at multiple locations.

First group out of Winchcombe yard were Dave, Phil, Peter, Polly and Jonathan. Their destination was Stow Road Bridge at Toddington. Today’s task was to complete the backfilling of the entry gully chamber; and then to add two rows blue engineering bricks as copings. With the backfilling complete, Jonathan returned to Winchcombe Yard to locate the materials for the replacement boundary fence, and to check out that the powered auger was working.

Found at Stowe Road, a tall narrow Bovril bottle with a long neck. This is likely to date from around 1900 to 1913, so may have been dropped by one of the navvies building the railway. [Photo by Dave]

 

Next to depart were Dee, Martin (J), Stuart and John Their first task was replacing a broken cess chamber lid at Didbrook. An easy task – once the offending chamber was located. Next they proceeded to Stanton Fields to undertake rodding out of the down side inlet bore of syphon cross drain 6C. This proved to be a tricky operation; the bore was almost bone dry and the obstruction was mainly soil. So each push of the drain rods only brought out a small quantity of material.

Final departure from the yard consisted of Ian, Roger, Martin (S) and Andrew. They headed to Manor Lane, Gotherington. Andrew went down to the slip site to inspect progress. The contractors have installed some additional perforated twinwall pipes in the reconstructed embankment. So the position of these were noted. Once the embankment reinstatement is complete, we are going to install new toe drains alongside the boundary hedge. These are going to run to the outlet of cross drain 37D. As the new twinwall pipe also drain into this, we will improve the exit chamber of this at our boundary. The outlet of 37C would be more suitable, however to use that we would need to make water run up hill.

Unloading of the infill delivered in Dogfish wagons from Cheltenham requires a shute and two excavators. When the material is slightly damp, it requires more encouragement to exit the Dogfish hoppers.

Meanwhile, the other three of this group attended to mileposts 16 and 15 & three quarters; either side of Manor Lane Bridge. Whilst both of these have bridge rail posts, their heads were the yellow BR style – made from fibre glass. These heads were removed (executed?); the bridge rail wire brushed down and then painted with black MIO.

Milepost 16 decapitated.

Same treatment for 15 & three quarters.

Next site for this group was Working Lane. Ian and Martin (S) performed some clearance around milepost 13 – mainly sycamore and willow saplings. Andrew and Roger met with Peter Brown, the Chief Civil Engineer, to discuss work to improve the drainage between the up side embankment toe and the Working Lane to Royal Oak haul road. This is the site of a historic slip, probably back in BR days. There is a french drain which terminates in a head wall that is now leaning at an angle. Also, the construction of the haul road after the Greet tunnel slip around 10 years ago has lead to some spots where water pools during wet weather. Our plan is to add some more pipes under the haul road and to dig out some ditches between the embankment and the haul road. Potentially we will tackle this in two stages, starting with a rebuild of the leaning headwall.

All three groups met up back at Winchcombe for lunch. After lunch some of the team sorted out and measured the fencing material for Stowe Road. The rest of the team continued with milepost construction. One length of bridge rail was wire brushed down, the new head for 16 was completed and one of the recovered hollow heads from Laverton was taken apart. This has not weathered at all well, the only reuseable component being the architrave at the bottom.

Wildlife report: Suddenly chestnut trees, both horse and sweet, are in full boom. Also in full bloom are the blue flowers of borage, lots of this at the foot of the Working Lane haul road. The cuttings and embankments which were cut back last autumn and winter are rapidly regrowing. And on those cut two years ago a lot of sycamore and ash saplings are pushing up. No unusual bird or mammal sightings today, apart from a skull found at Stanton Fields. This looks to us like it was once a fox.
