Modellers block for a couple of days, pretty sure the Metcalfe brewery will go in the middle of the shelf.
There are some nice combinations creating a long platform servicing all the buildings, so this would suit the long straight track at the back.
At the left hand end I'm thinking of combining a couple of warehouse kits to make a large structure as a contrast to the smaller buildings at the right hand side. I think the crane in the same are would be a bit too much, so this could be moved to cover two or three tracks at the front yard standing. By adding a small building here, it should give some focus.
Opposite end to previous entries.

This platforms a bit chunky, maybe when it's painted it will look better.

Crane over 1 track at the moment, could be extended over all 3 with some work.

Brewery will go along the backscene in the centre of the board.
Alternatively I move the crane left of the bridge and simply put another factory along the front. Had half a mind to build something like the peco goods platform as well.

Remember, it's a hobby, not a headache.

Thanks for looking.
