Check out this AN layout in 1984 the Kanunda & Emu Flat Railway ( K&EFR ), Ken has put a lot of thought into operations. Looks like it fits into one half of a garage, and has dedicated enough room on the layout to give Penstone Quarry a bit of dominance.
Shunting Penstone Quarry:
The design concept is solid, he has managed to squeeze in three mainline stations, a branch station and the quarry, and ample room in the fiddle yard. I like the controller holders located around the layout. He has also ticked the ease of operation box, as the layout is a total walk in design.
Importantly it seems to satisfy his requirements quite nicely, congratulation with your slice of 1984 AN.
