10th April
Always have a plan B, and a plan C. A
good mantra for any activity; though sometimes the formulation of the
alternative plans takes place ‘on the hoof’. Today was a good
example.
First of all, a job that we had
expected to undertake but we found another team had already
completed it. This was the replacement of some fencing alongside the
Wychavon footpath near bridge 2, Childswickham Road.
Secondly our plan to use both of the
Transit vehicles had to be changed. The white tipper Transit was out
of action requiring repairs to the tail lights. Jonathan in his
capacity as chief vehicle maintenance person spent the day sorting
that out.
Final item of replanning was the
rebuild of the down side syphon inlet chamber of cross drain 39B at
Two Hedges Road. To obtain level brick courses with even mortar
joints, we decided to remove a few more of the existing coping
bricks. Hence the plan is now an all brick chamber with concrete
lids, instead of GRP catch pit rings and a blue mesh lid.
Whilst the Toddington to Stanton
section of the B4632 road was closed for gas main replacement, a lot
of traffic diverted along Laverton Meadow Lane. This prevented us
from working under bridge 6 to clear the silt traps. Now the main
road is open again, we could safely attend to this. Hence, Dave, John
and Martin just managed to squeeze two wheelbarrows, traffic cones,
road work signs, shovels and rakes into the Ranger for this task.
Almost a month of dry weather made this task a bit easier than usual;
however the silt in the traps on the low mileage (Broadway) side of
the road had the consistency of thick soup. Then back to Winchcombe
to clear out the final Drainage items from the office in the old
wooden C&M workshop that is soon to be demolished.

Nigel, Stuart and Roger were deployed
on the rebuilding of the 39B inlet chamber at Two Hedges Road. Again
the effects of the dry spell was obvious, no water was flowing
through this. However, a work platform was required in the chamber to
keep the bricklayer feet above the sump. The removed coping bricks were taken back to Winchcombe to join our stock of spares.

Peter and Andrew also headed for Two
Hedges Road, but south of the bridge. They inserted some more sandbags
around the end of the length of 600mm diameter twinwall pipe in the
down side crest ditch which carries the stream that comes down from
Cleeve Hill alongside the former Bonsai World site. Next was some
careful measuring of the ditch further south. The plan here is to
pipe the stream for around 60m to avoid the sections where water is
seeping into the cutting side. We also noticed some damaged lids on
cess chambers where a non-railway drain pipe under the line. So these
were measured up for replacement lids and additional chamber rings to
raise their height.

After lunch all nine of the team
attended a presentation from Gareth Mead of Severn Trent Water.
Gareth explained the somewhat opaque division of responsibility for
drainage between water companies, Environment Agency, high ways
authorities and landowners. He also showed us a water testing kit
that Severn Trent use to determine levels and type of contamination
in water courses. The main item was revising the internal Severn
Trent maps of all the pipes and water courses which run alongside or
under (or over) our railway. This was very useful, as we now know
what some of the pipes are; and know of some more (such as one
running under the filled in bridge 41). [This included the pipe we inspected earlier between cross drain 40A and culvert 40B, this is a combined foul water and surface drain pipe, which does belong to Severn Trent.]
Wildlife
report:
The
team at Laverton Meadow Lane spotted Cardamine
pratensis,
the cuckoo flower, lady's smock, mayflower,
or milkmaids; plus
the expected primulas in flower. Whilst at Two Hedges Road, the
resident flock of gulls was noticeable fewer and quieter. On the
ground we
spotted a hairy-moth caterpillar taking advantage of a flowering
white dead nettle plant. Very early signs of blossom was seen on some
apple trees, whilst blackthorn and some other varieties of Prunus
(which includes ornamental cherries) are in full bloom. Also noted
was the first sighting of a cabbage white butterfly this year.
