This week will mark a turning point in the repair-works at
Gotherington.
A turning point that signifies that we will be able start
relaying the mainline!
However the site is not yet ready to decamp and fully hand back,
there is a lot of work yet to be undertaken to complete the repair
in full and allow us to run the special opening service and public
trains across
The last area to be fully excavated Area 6 (We should have
started the numbering at 45…..!!!!) is in the process of being
completed and the requirement to fully excavate this isolated slip
has proved a wise move indeed. It was one of the older slips,
didn't have any temporary repairs from BR days such as a gabion
etc., and on the face of it appeared small. However the bore
holes suggested that something quite major had happened deep in the
core at the same time as Area 2 and it has proved true.
When you look at the photograph you will see that the edges of
the excavation show what would normally be expected, a clear
defined area of clay embankment with an overlay of soil and
ash. Within the area excavated the embankment was remade up
of several meters of soft ash fill that had been dumped onto a
slump and hole. The bottom of the embankment at around 6m had
slipped out, the polished soil found when excavated where it
slipped was a clear indication. However a second slip was
discovered deeper below the first slip area that had cut into the
ridge and furrow. This has all been broken up and out and new
material rolled and compacted in so the at the repair in addition
with the reinforced soil berm support, will stand us in good stead
for generations to come.
Walsh's the contractor undertaking the main works and GIP ltd
who are looking after the geotechnical side of things now vacated
the top trackbed section and retreated sufficiently to the lower
section of the embankment to allow our P-Way team to start safely
relaying the main line. The loop section will follow BUT,
before the inevitable question, ………this doesn't at the moment mean
that we will be bringing the date forward for re-opening to
Cheltenham.
In fact whilst originally running slightly behind program due to
the snow, Walsh's have made up time and we are back on target for
22nd April, as whilst the track laying may only take a few days,
there remains the re-ballasting, tamping and alignment, along with
reinstating the signalling and cabling that ran across and along
the formation.
With completion soon of the main works at Laverton, the timing
will be just right to then run the P-Way train up towards
Cheltenham and a number of maintenance jobs that are required to
re-fettle our mainline back to good health after a long period of
hibernation.
Whilst that is going on there are a number of final works that
are awaiting funding to complete the repair in full before the
contractors can pull out and for which your continued contributions
are so critical.
We have some additional drainage to put in on the Malvern side
along with lining of the culverts which couldn't be undertaken
whilst all the heavy plant was in place programmed after the main
works, after the worst of the winter (in hope and
anticipation!). We await sufficient funding to complete these
works before we start assessment at Chicken Curve. As
promised we will try and undertake a full Q&A on Chicken Curve
in a subsequent update.
One final thing that it is worth adding as a summary at
Gotherington is the complexity of what we have dealt with.
Its not just one repair. Its been a combination of several
problems that combined with the terrible weather broke the back of
one section of track. Not a complete list but we have dealt
with 7 different slip defects, four culverts, three different
drainage problems including a new pipe and outflow that hasn't been
active for decades, and we have also started to address drainage
issues at Far Stanley just between Gotherington and Greet.
Great progress has been made, solely down to your contributions
big and small. More work to complete………watch this space for
the next update.
Funds permitting…the process will start afresh on Chicken
Curve.
