The river itself was a little bit of a problem, as I had very little space between the top level and the hidden lower level that carried the return (runaround) track. I had to use a piece of sheetmetal for the riverbed. After the river was painted a muddy grey and two layers of Woodland Scenics water were applied and some fallen trees and debris added, I was quite happy with the result. I will probably add more vegetation along the banks.
The actual backdrop behind the bridges is really quite wooded, but I left it as I had painted it, with distant hills, as it gives the scene more depth.
The track from the bridge around towards Cathkin consists of a rather tight curve and gives me trouble once in a while, so this is something I may have to look at again in the future. The same thing applies to the curve in the opposite corner, leading from the Cheviot Tunnel into Molesworth.
It is time now to bravely move forward to Cathkin...
