Hi Jon, great pictures, and looking good. Noted your comment about ballast lifting when cement applied. Give it time, and let the glue mixture seep in a bit, I then i use a small screwdriver, to re-distribute the ballast, sort of push it where i want it, yes, probably not the best method but once the balast is placed again, it stays there. I will get round to starting a thread soon, once i've finished altering (not for the first time but hopefully the last) the track layout of my TMD and get some pictures placed so you can have a look.
Keep going
Tim
