Pauls Valley rebuild

As a temporary measure, Pauls Valley was originally laid out with old Peco code 80 track that I had salvaged from my previous GC&SF. Over the past few months I have completely rebuilt the town using Atlas code 55 track, and then installed push-rods to operate the turnouts.

Here's how the town looks:

At the same time, I also relocated the control panel and video monitor for the north-end staging yard's return loop, from the centre of the fascia, to the end.
