The eBay purchases arrived, one of which, although advertised as spares or repair, does actually run. Haven't spent much time on these yet, still looking at the best way to convert the 0-6-0s to three rail running. Not sure if it's easier to use Marklin skates or Dublo ones.
Meanwhile I've now laid 2 running loops and down one side of the layout these run into four, with an additional fifth centre line which I will leave for further expansion at a later date. I also added more sidings and started building my terminus, firstly checking that the locos could enter an exit without stalling or derailing. So far, the Deltic, Diesel Shunter, 0-6-2 tanks, 2-6-4 tanks, 8f and even the Bachmann EPB have all managed to exit the terminus, run round the outer loop and back into the terminus again without fault so I'm happy!
There are no diagrams of the proposed layout, although I consider myself to be reasonably pc literate I find it easier to just loose-lay the tracks on the boards. I decided to use a mixture of manual and electric points, the ones near by will be easier to leave manual - less wiring, less modifying, less hassle!
Still plenty of work to do but with the weather chilling off and Xmas fast approaching I don't envisage much more progress in coming weeks...
