The dig at Stanton

Saturday 18 May 

Another wet start, first off we brought the rest of the pallet of bricks down so they are ready for starting on the up side cess headwall.

Concrete footings have set 

That will teach Roger to have a day off 😉

Then the real work begins, only 3 of us here today, quite a difference from the 7 we had on Thursday. We concentrated on digging out the old salt glazed gully pipe, we're doing this early in the project to keep the track under the bridge drained. There's not much more to say about digging a pipe out, the pictures will tell the story.

The new twinwall pipe was dropped into the trench to check the length, we'll take some levels next week to make sure there is a fall on the pipe

Outlet end, a bend needs to go on here 

The spoil heap is always a good reminder of how much has actually been dug out. This will be used later to backfill the new pipe on the down side cess. 


Not bad for couple of days work 

On the way out we dropped the new lids onto Chamber 3 on the down side crest. It's a shame all Michael's brick laying so far has been hidden by lids.

Back at base there was a couple of surprises, first there was a bag of milepost number patterns, thanks to Eddie and the woodwork team. We now need to get some moulds made so that the numbers can be cast.  

What! no 6's 

James from the C&W metal work team has nearly finished the covers for the inlet end of the siphon at Culvert 7A. Next job is to take it up to Stanton for a trial fit and work out the best way to fix them onto the walls.

Thanks again to the Carriage and Wagon volunteers for all their efforts, it's a great demonstration of the skills we can call on and the interdepartmental co-operation that thrives on the railway.

  1. A lot of graft there gentlemen, can't make out as there is two drainage systems side by side.

    1. The gully drain top is below the high water level in the culvert channel, so of we tapped into the culvert then the water would run out onto the road making the flooding worse. The gully is to drain the roadway so it runs parallel until it can drain into the stream below the end of the culvert.

      If we lowered the culvert that would mean rebuilding the bridge abutment as we would probably be below the foundations.

      It's easier to see when you look at a cross section

  2. Could you not have gone through the half pipe wall from the drain, less possibility of the pipe being crushed by tractors?

  3. Hi
    Don't forget your iPhone has a level (or inclinometer) built in

    1. You need to download it for Android phones - We could do it with a spirit level but the laser level is best in this environment
