I was going to do it next year but i have decided to do some ballasting, mostly under the new bridge. It will be difficult to ballast when the bridge is completed so i decided to ballast it now. I've extended the ballast to cover the approach roads to the station and MPD. It all looks reasonably good... so far.
The bridge will be a railway bridge by the way. I will get some HO scale stock for it one day but for the moment a couple of carriages from my stored OO scale fleet are being used!
