I would have thought as you are on London clay that you would have laid your ballast on terrain matting to keep it free from clay and mud rising through the ballast?
Luckily we don’t have too much problem with that as the surrounding land drains pretty well although for this renewal project we did cut out some clay in certain sections to make a deeper foundation and put some type 1 stone in so the bottom ballast sits on that. In other places we scrape some of the old ballast that we can re-use and compact the rest to form a new base before new ballast on top which seems to work well for us.
Great work everyone! See you all soon ! From Andy and Tristan 😊
I can remember laying the first track to, and through, Eleanor's back in 1986!

Shame the old turntable well was filled in.
