Saturday 21 September
Out to Royal Oak, Gretton, the south end of Greet Tunnel on a three-fold mission today; first off to clear vegetation from Culverts 24A and 24B and the outlet ditch, secondly to catalogue the cess chambers on the run from the portal and the cutting crest. The third job (depending on who you were watching) was to catch the last of the summer sunshine, pick blackberries or estimate what materials are needed for the 24A down side rebuild.
This year the vegetation growth has been phenomenal, the good thing about Royal Oak is that the lineside clearance contractor has cleared large parts of the area. We "just" have to do the ditches and headwalls.

It's not all easy going though, despite the trees being removed earlier this year...

Culvert 24B up side headwall was rebuilt in November 2016, it now needs a bit of scour prevention below headwall apron.

The rebuild on the down side of 24A has been on the list for a fair while, it was partly dug out back in December 2015

You would have thought that we would have learnt by now not to poke around when we see something. We haven't, one of the sharp eyed operatives spotted a bit of wire sticking up in the grass near the truck at lunchtime. Being good corporate citizens, we decide to pick it up, only it turned out to be a bit of rebar still attached to a rather large lump of concrete. It looks like an over-engineered end post for a wire fence, it must have had that big foot around 4ft deep in the ground when it was set upright.
