Saturday's travels

Saturday 11 January 

The team got split up this morning, Roger, Dave and Michael went to Stanton to peg out at Culvert 11B before going down to Southam Lane with gabion stone. On the way they checked Bridge 6 at Laverton and Bridge 16 at Didbrook to make sure that there was no flooding following the heavy rain on Thursday. Stuart had a look at Winchcombe cutting and then headed off to Hunting Butts to talk about fencing via a check on the slip at Gotherington. After lunch there was a quick recce out to Dixton Cutting to check on the boundary around Culvert 32A. 

First batch of photo's are from Dave at Stanton.

Working out where the end is 

The Culvert 11B drain work is to take away the wet area on the down side around the culvert. The water runs in off the field and catches in the embankment toe

It looks like there is a deer path across the track just north of the culvert, we've spotted a couple of roe deer around here a few occasions, they must be crossing the track on regular basis. 

Deer tracks, have they been PTS trained?

The gabion stone had to be hand loaded today, no digger handy on Saturdays ๐Ÿ˜’

Picking out the best stones, no dross on this load 

The wiggly tin roof from the container was removed in the week, the sheeting has been taken back to Winchcombe for re-use by another department

Roger went down to look at Stanway Viaduct, the south end pits are being backfilled with hard limestone. Plastic sheeting has been laid over the original GWR waterproofing to add an extra level of protection.

Both Laverton and Didbrook bridges were clear of water, Didbrook gully drains were cleaned, the last of the leaf drop was still lingering on the tops.

The gabion unload at Southam Lane (Bridge 42) was another bit of keep fit ๐Ÿ˜‰

Thursday evening saw some more heavy rain, looking at the flood data for the River Isbourne it shows it was a bit of deluge. This meant a check of the landslips was required to see if there had been any more movement. 

River Isbourne level data 


Winchcombe up side slip is still holding steady, but there is evidence that the water from the adjacent land had over-topped the crest on the down side and run across the track.

Gotherington slip near Bridge 37 is on the move still, the chamber at the toe has almost disappeared, there was 8" of lid showing last Monday. There are signs on the slip face that it has dropped by about 6".

Back at Winchcombe work has started on the down side of the River Isbourne. There's a considerable amount of spoil to move to get the river back on its original course.

The Dixton excursion was to check if there is any evidence that the railway land extended beyond the current fence on the up side and to see if there is any obstructions in the brook that are impeding the flow.

  1. That Gotherington slip is really on the move!
    Any info on when and how it will be dealt with? (I assume contractors will be doing the actual work.)
    These slips are really trying; hopefully there won't be too many more! They've got to be causing money to be diverted from other things the GWSR wants to do.

  2. Hi Noel, the consulting engineers are looking at the data from the core samples they took. They will determine how best to stabilise the embankment, it's going to be quite a big repair job.
