Time flies when you're (not) having fun.
Finally managed to get Trowland onto the dining room table to fix the tiebar and the dead section that appeared at a rail joint (and temporarily bridged) when I last had a play (back in August!).
Fortunately Trevor provided a wiring diagram, the dead section shown with the green arrow.
I had power from the "Barry Slip" but nothing towards the goods shed and no seperate feed to that piece of rail. There is a wire to the crossover microswitch from the dead rail (blue arrow) so it was a simple matter of linking that across to the feed from the Barry microswitch (red arrow, red wire).
All of which would have been a right pain in the proverbial if Trevor hadn't had the foresight to make the platform removable.
The tie bar just needed a tickle with the iron and the timbering glueing back. A spot of paint will complete eventually.
Now the printer is back up and running i have a pile of small scenic bits to print and fit, barrels, crates, sacks etc
Only 3 months to Taunton.
