This much better. Is there a fiddle yard at the side of the brewery ?

If you pretend there is a loop there,  you can imaginary let a loco run around.

Maybe you can add a small signal box where the track goes to the siding.

Yes, I think it flows better too. There would be a 'fiddle stick'/cassette, and I agree, would be tempted to lose the trees (or move them to the other side of the river) to accomodate a signal box as well.

Is your track to Cuckmere Haven long enough to hold the loco of your passenger trains?

Or have you planned here also a fiddle stick cassette.

Another fiddle stick here too, Job - so that trains to/from the shingle loading can run straight through, as well as allowing the passenger loco to run around.
