A little progress...
I managed to glue all the foam down using cornice adhesive and I started to lift the old track that gave issues. These were the extending tracks - PITA they are! They cause a lot more derailing than anything else. Gotta go. Managed to remove 2 so long with 3 more to go.
Have a lot more track to lift as I have 4 points that created a DCC reverse loop and I am not going to wire it up on the left side like that - I might move it over to the right side, but I have not made my mind up completely.
I also went in search of my Peco track - I have them stashed all over the place and then made a decision to use concrete sleeper track. I was going to use code 55 but I don't think I have enough to do all 4 tracks across the bridge, but I do have enough code 80. So be it then...
This then led to me searching for my fishplates. Oh boy... this drove me insane as I spent days looking for it. Seems at some point I took them out of the container I had them in for 24+ years and repacked them into a tray, which I found at last. Man, that made me very angry...but I can continue again!
Will post back pictures once I have some visual progress.
