Hi Peter,
I've just been browsing this thread and was struck by your plea for comments. Overall, this is a very impressive model, and I particularly like the flowing trackwork and the operational potential, but I've a few queries of comments.
First, I think you need to lose the lighthouse. Lighthouses are located on headlands and at the mouth of harbours. Your quay is presumably located in a bay or estuary, with shelter provided by the surrounding land, so the lighthouse would be on the headland, possibly several kilometres away. The mouth of a navigable river would be marked with buoys, red to port and green to starboard, but your river is not navigable because of the non-opening railway and road bridges across it. You might have some kind of marker light on the small headland between the quay and the river to assist shipping heading for the quay, but I think that is as much as might be there. (Trust me on this, I'm a sea kayaker. )
Second, the road bridge should end behind the warehouse building, not in front of it, because the road has to continue on in front of the building. Indeed, with the bridge and warehouse so close, I'm wondering how you get off the road and into the warehouse. Could you build a warehouse so close to a road on an embankment? Could you build a road right there if the warehouse was built first? (Don't necessarily trust me on this, I'm not an engineer.)
Third, I'm a bit surprised at seeing a cattle dock at the end of the main line into the branch platform. Wouldn't the presence of wagons in the dock block the entire road and prevent any train arriving? Surely the home signal could not be 'off' while there are wagons in the dock? I know Leighton Buzzard has something similar, but it's effectively a siding off the release line, and all movements are signalled into the platform road. (Don't trust me at all on this: you may have some prototype in mind where this happened, and anyway, I'm neither a beast nor a stationmaster.)
Quibbles aside, it's a lovely layout and I hope some day I can manage something half as good.
Best wishes.
Alan
PS - I meant to add: post bigger pictures so that we can really admire the quality of your modelling. (Please.)
