and the [presumably!!] final one:

Monday 18h30

​The P way team and Signalling maintenance have been out all day and have laid the final rail. The Railway is whole again. There will be ballasting tomorrow morning but we will be operating full line again although a speed restriction will apply over the newly laid track.​
A speed limit of 5mph has been imposed for the Trimpley site

SVRLive update 18/2/15

Quote:
18/02/15. Final update. After frenzied activity by contractors to fill in the worksite, it was finally handed back around 3:00pm on Saturday 14th Feb. This put the track laying behind so a decision was made to delay re-opening until Tuesday 17th. Volunteers and full time staff assisted by contractors plant, completed the connection of the two halves late Monday afternoon. This was a huge effort which has thankfully resulted in trains running normally with the exception of a 5 mph speed limit over the hastily re-laid track. Further relaying and tamping will take place in the weeks following half term.

The Permanent Way Team and Signalling Maintenance have since the New Year, been working on both the Arley Points relay and the Elan Valley Project. In the last two weeks, the amount of effort thrown in to the latter project in particular has been exceptional.

I am pleased to announce that whilst fettling is needed the Railway is whole once again and everyone involved in the Elan Valley project or running the Railway during the interim is owed a debt of gratitude.

The Chairmen of both Companies Nick Paul CBE and David Williams representing all the Directors would like me to express their sincere thanks to all.

We've handed back the Severn Valley Railway

17th February 2015


Since the start of the year, we've taken over part of the Severn Valley Railway tracks at Bewdley. The work to replace huge water pipes is now complete and we've now handed back the tracks to allow the railway to run as usual.

Programme manager, Michael Lomas, explains: “We’re responsible for supplying water to our customers everyday, and for making sure it’s there in the future. For these reasons we constantly check on the condition of our infrastructure and we think now is the right time to invest in some of our biggest supply pipes. The Elan Valley Aqueduct (EVA) has been bringing water from Wales to Birmingham for over 100 years. While it's served our customers well, our regular checks are showing it needs some modernisation and refurbishment.

“Part of the aqueduct runs across the River Severn at Bewdley and on towards Birmingham, and it’s this part that needed replacing. This was a huge undertaking and a really tricky job because the aqueduct at this point is made up of four pipes, and just after they cross the river, they were encased in several feet of concrete.

“To get at the pipes, we used a specialist technique of hydro-demolition, where we used extremely high pressured water to break up the concrete. Once the concrete was removed, we then replaced sections of three of the pipes, meaning that water supplies are now much more secure.”

The pipes are in a part of Bewdley that’s really difficult to get to – access was via a narrow single track road. And so we came up with an unusual plan. As the work was happening on the tracks of the Severn Valley Railway (SVR), our engineers worked with the SVR to use the railway to move plant, equipment, and materials to and from site, with a temporary office based in the station grounds.

Michael added: “We’re really grateful to the SVR team, most of whom are volunteers. They worked fantastically hard and showed real interest in the project. This made the job much easier for us and allowed us to get the work done in a much more efficient way.

“The work is now all complete, and the tracks have been handed back to the SVR. Unfortunately, a number of difficulties meant that we were late completing the work and so the SVR planned timetable was disrupted for three days. We’d like to apologise to anyone affected by this and we agreed with SVR that affected passengers should be compensated. Going forward, we’ve agreed to become one of the SVR sponsors, so we’ll continue to support this fantastic part of our heritage.

Michael continues: “This work is part of wider plans we have to modernise and refurbish parts of the Elan Valley Aqueduct. To allow us to carry out work on certain parts of the aqueduct, we will need to shut it down for a short time. To allow us do this for any decent amount of time, we’ll need to have an alternative supply of water for Birmingham. So we plan to build an extra pipeline to take water from a new place on the River Severn. This will give us a back-up supply of water to Birmingham during the refurbishment work on the EVA, and in the future in case of emergency. We’re still in the planning stage at the moment, and we’re in the process of talking to anyone who could be affected by this work."

It seems quite fitting that a water company should sponsor a steam railway. Smile

The second phase of work on Wribbenhall Viaduct has now commenced. A road closure has been activated to allow contractors free access under the road arch. Stitching the areas of delamination is taking place using resin anchors and grout. Pointing work is also being undertaken using the correct lime mortar. Although the road is closed for three weeks, the contractor hopes to finish ahead of schedule which will be of great relief to Bewdley residents.

Winter works 2018

I am pleased to report that the efforts of the full time staff and volunteers during the shutdown were completed in time for the half term running week. A flurry of ballast trains using our recently acquired “Sea Cow” hoppers and a four day visit from the tamper ensured all was ready for the half term trains. The track at County Boundary has been returned to line speed and improved riding along the line in general has been reported. The plain line in Kidderminster Yard is now much improved.

In the non-running weeks after Half Term, we are carrying out further works to make use of the time available. Up in the cutting by Bewdley Tunnel, contractors assisted by volunteers are clearing the more difficult to reach vegetation that has grown up since last cleared a number of years ago. This will be supplemented by clearance by volunteers on top of the cutting in due course. At Bewdley North crossover, the central section of the assembly that includes the crossing blocks has been dismantled. This job was programmed for several years’ time but due to its rapidly worsening condition, the opportunity to tackle the job this year has been taken. Around 20 badly rotted timbers have been replaced and a some new ironwork inserted. The job is taking place over two weeks with the mainline being restored for the intervening weekend. This will mean the down main through platform 1 will be out of use but the Operations teams have ensured we can still cross trains using the island platform.

The Bridgnorth gang will also be using the time to bring in a mini digger to sort out some badly dipped joints just to the north of Country Park Halt. By excavating well down and filling the resultant hole with fresh ballast, this will provide a more solid foundation to pack the joints level and for them to stay that way.Six images added.

Winter Works 2018/19

December 5th 2018
It may be a surprise to some that one of this winter’s projects has already taken place, namely a 600ft (or ten 60ft panels) track relay north of Arley near Bank Farm Crossing. The work was required due to the high number of poor quality concrete sleepers that had started to fail on this section and was carried out during two weeks of November. The track that replaced the original was flat bottom rail on steel sleepers and has effectively extended the existing flat bottom track northwards. The reason for this early relay is down to the other projects planned for the Jan/Feb shutdown and the need to have sufficient Permanent Way resources to do these.

The first of these projects will be the first phase in renovating Borle Viaduct. This was subject to waterproofing works back in the 1970’s and is now showing signs of fresh water penetration so requires rectification. A contract is being let for the removal of the fill material down to the existing concrete “flaunching” where any degradation will be treated and some additional drainage discharge points provided. The whole area will then have a high specification sealer applied before layers of new imported fill material is laid. The track will then be replaced and the whole lot ballasted and tamped. Although originally there was no edge protection on the viaduct, in later years sets of post and rail fencing has been used. This will now be replaced with more appropriate steel tubing fencing as used elsewhere on the SVR.

The second major project will be the second phase of turnout replacement in Kidderminster yard. The yard was laid many years ago using recycled components and during this period has probably experienced more traffic movements than anywhere else on the railway. Consequently, it is now totally worn out and action required. During the summer the turnouts that serve Carriage Shed siding 1 – 3 were replaced with virtually new materials and the severe curve into siding 1 eased. Due to the implementation of the next phase causing the isolation of the whole yard, it was decided to carry this out in the shutdown when usage is reduced (although not completely). Another two turnouts are due to be lifted scrapped and replaced as previously carried out. Hopefully the timing of these projects will run seamlessly into each other but even with careful planning the weather can make or break things.

Further to Derby4’s observation today on https://forum.svr-online.org.uk/viewtopic.php?t=4221&postdays=0&postorder=asc&start=3

Winter Works 2018/19

January 16th 2019

One of the main winter projects for 2019 is remedial works on Borle Viaduct which was highlighted in the 5 yearly line report as suffering from water penetration from above. This leads to erosion of the structure from freeze thaw action which is not good for its long term health. It is known that some work was carried out in the 1970’s by the then SVR civils team including the application of concrete to the top of the arches and the installation of tie bars to arrest the outward movement of the spandrel walls. After some 40 years it has become time to investigate why water has been circumnavigating the concrete and causing significant wet areas on the underside. After a competitive tender process, Stepnell Group were awarded the 6 week contract to carry out the job.

The first job was for our PW team to remove the track as soon as the engineering possession was granted and this duly took place on the 8th of January. The first task by the contractor was to scrape off the ballast for re-use later. Stepnell’s staff then rapidly started the task of removing the large quantities of fill material for depositing on the site of the former Kinlet Colliery sidings to the south of the viaduct. This is made up on a motley collection of ash, dirt and clay-like material, the best of which will be re-used when the viaduct is backfilled. The remaining dirt is then blasted clear using an air hose so that close visual inspection can be made of the existing concrete.

To date it has been found that when the concrete was installed in the 1970’s the edge of the area filled was shuttered and a mortar capping applied to seal it. Over the years this has failed and the shuttering rotted away. This has allowed water to get below the concrete and caused the water penetration that has been noted - the plan is to seal this gap with a suitable modern compound.

Generally the concrete is in good condition but will require adding to in places to create sufficient fall to the new drainage points that have been core drilled to provide a means of escape for rainwater. Interestingly, the wellington boot marks of those early SVR pioneers are preserved like dinosaur footprints in the 1970’s concrete and perhaps those who took part in the exercise may remember the vast quantities shifted by hand?
Once the repairs and fettling have been completed, the backfilling will begin with the aim of handing back to the PW in plenty of time to relay the track back across before the February half term running.
