County Boundary back to line speed

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’ (rather than switch and crossing) 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 with 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.

County Boundary re-ballast

At County Boundary, the last part of the work is being carried out so that the line can be returned to line speed at that location.

This involves the removal of 70 meters of track and the excavation of the ground below the normal ballast level.

This is composed mostly of ash and the resultant spoil is being shifted to location at the former Kinlet Colliery sidings.

The lower part of the excavation has a plastic “geomesh” laid and imported fresh stone material deposited to a depth of 300mm.

This is overlaid with another layer of geomesh followed by ballast to a depth of 450mm.

The track is then re-laid, ballasted and finally tamped. This work (recommended by the SVR’s consulting engineer) will ensure that we do not suffer future settlement problems as a result of the slip and subsequent remedial works. It has of course resulted in diversion of resources from some of our other planned relaying work but will hopefully negate further visits to the site to repack. (pics by Leigh King, PW Dept staff)

winter works, smaller projects

We’re in the middle of the engineering-works six-week closure when projects can be tackled that require no trains to be running.

Infrastructure Manager Chris Bond reports that this winter sees several smaller projects taking place at various locations rather than the large track relay we saw in 2017 at Waterworks.

 A 500m section of bullhead track from Bewdley Tunnel to the Stourport Road bridge is being cleaned of badly contaminated ballast using a special shaped excavator bucket. The spoil is being removed to an area of the former sugar beet sidings for disposal. The length of track will then be re-ballasted and tamped. It is also intended to weld together the rails to create a length of bullhead CWR which will require the insertion of a pair of breather or expansion switches at the Stourport Road bridge end. At some point in early 2018 we hope to get a Colas rail grinding train to re-profile the railhead to remove the corrugations that cause poor riding.

On the Bewdley side of the tunnel, contractors are using a mini-digger to remove the ballast shoulders using a riddle bucket to remove contamination. The clean ballast is then being placed in between the rails in preparation for fresh ballast to be dropped and the track tamped. The shoulders will then be reformed. This work will provide fresh ballast for the tamper to improve the ride and help to remove wet spots that have forming on that section.

A project funded by the Friends of Eardington Station is also underway during the shutdown involving the partial rebuilding of the platform face. Although the station does not currently feature in our daily operations, a dedicated team lead looks after and maintains this wayside gem. The rebuilding of the platform will improve greatly the appearance of the station and allow consideration to its possible use on gala events at some point in the future. Some 8000 engineering bricks recovered from the London – Bristol mainline and donated by Kier Construction will be used. These have been cleaned up by the team over a period of time and will provide a genuine connection to the GWR. The rebuild is being undertaken by JSR Construction who are based less than a mile away from the station thus keeping the work local.

At Kidderminster, preparations are underway for the lining of the loco water tank similar to that carried out at both Bridgnorth and Bewdley. This work will require the draining down and drying of the tank interior followed by shot blasting. This provides a strong key to the GRP lining system that is then applied to the bottom and sides of the tank interior finishing off with a gel coat. This work is proactive maintenance of the tank and will greatly extend its life for a relatively modest cost. It is being carried out by Project Linings Ltd who have done the other tanks on the SVR to a very high standard.

The Kidderminster water column adjacent platform 1 runround is being swapped out from a fixed column to a standard GWR swing arm type similar to that on platform two side. This project has been a long time in the making having being on the cards since the 1980s. Although the current fixed column is an original Kidderminster GWR item (having been cast at Wolverhampton) the swing arm replacement will be better suited to the variety of engines the SVR sees. The replacement has been restored and new components fabricated and the original fixed column will for now be retired to the custody of Kidderminster Railway Museum for possible display.

WWCC Tues 17 Nov

Today, even under the threat of gales associated with Atlantic Storm Barney, we managed a crew of seven to tackle the day’s operations. Chalky and Geoff set about excavating the ballast to let in the new troughing run under both sets of rails. The remainder of the crew set about some serious block and bricklaying.

wwcc17nov2

In places from the position where the new ramp will start, we have now got seven courses of brickwork in place towards the south. This section is backed up with blocks to the same height. To give Colin a little break, other crew members have been involved with both brick and block laying. The next stage is to start the corbelling over the next four courses to the level where the platform edging slabs are ready to be installed.
