Monday 14 October
Change of scene today, still following the theme of clearing vegetation and preparing for the upcoming structural examinations. There were 5 of us today and with poor weather forecast, we quickly headed off to Bishops Cleeve to open up Bridge 41. This is the phantom bridge, we're not talking McDonnell Douglas F4 here, it's just an occupation bridge that is no longer used. It had the ends filled in some while back to prevent it becoming a congregating point for vandals. After doing the bridge and clearing 3 culverts, a start was made on recording the chambers along the drain run past Kayte Lane and Southam Lane to the racecourse.

By lunchtime the rain had started to come in...

Unusually for Monday there was a train running, Class 50 50035 Ark Royal was out on a charter as a thank you to the Class 50 Alliance who allowed the loco to visit for the summer.

In the afternoon we went round to Southam Lane clearing the cess chambers on the way. If left they tend to get lost and then the robot flail knocks the lids off.

The cess drains run along each side from the end of the Cleeve straight to the racecourse, then they discharge into open ditches to run out to Culvert 42A.

Some of the chambers are easy to spot, luckily they are usually opposite each other as some are a bit more clandestine.

On the way past we cleared the double siphon at Kayte Lane (Culvert 41C). The stream runs in 2 pipes under the track to emerge on the up side.

As the siphon runs down under the track, it fouls the line of the cess drain. To get round this the cess is diverted to pass under the culvert outlet; this required 2 extra chambers to be added on the corners of the diversion.

This cess drain is one of the longer runs, with 34 catchpits on the up side and 32 on the down.

By this time the rain had become persistent, so we decided to head for home.

On the way out we put some hazard fencing on Bridge 41 until such time as we can get back to cover the opening.

A not so quick stop off on the way back to look at Culvert 28A, it involved a detour to avoid the roadworks at Gretton 😞. The temporary fix we did a couple of weeks back, by adding rings and opening the hole where water was running out seems to have worked.

Back at Winchcombe the down side stream is going well...

All the way to the Isbourne brook!

Did you decide why there was so little water in the 40 & 41 drains?

Hi Powli, it's not running off the fields yet, it needs to be flood conditions for some of them.
DeleteI see, thanks for the clarification, These are most interesting blogs about an otherwise completely unseen aspect of the GWsR (and all railways) and with a 14 mile line along the edge of the escarpment absolutely vital but never ending work for your team.
DeletePowli (I use this name because there are several "Paul's" reading these blogs i have noticed).
Good work guys.
