Many people picture only rectangles when they think of model railroad
layouts, which I guess is natural. The commercial model railroading press feeds the newcomer a steady diet of cramped HO 4X8 track plans plopped on a pristine sheet of plywood.
there are spaces with unusual obstructions or small overall dimensions that significantly limit the size of a rectangle that
will fit. Here's an example in an 8'X8' room where a 4X8 sheet wouldn’t even fit in the room, let alone
allow for the aisles.
If one thinks only of rectangle "Island-style"
layouts, then something like Atlas' 4X6 Morgan Valley RR is about the only option. (Plan HO-30 from Seven Step-by-Step Layouts.)
But if we free our thinking from that rectangular confinement, we see
that even this small space can yield an interesting layout in HO scale. Here we take advantage of three key concepts: -
Place the layout against the walls, with the people in the middle - Allow the benchwork to curve with the track -
Nest curves of track in the corner
By essentially folding the oval in the middle, we can place a much larger
and more interesting layout into the space than a rigid rectangle would allow. While I've drawn this track plan level
to optimize the passing sidings and space for industries, an up-and-over crossing would also work fine.
the 18" minimum radius, the back corners of the end loops are just out of easy reach (30 inches or less). So
I've added access areas for each. But all turnouts are easily reached from the main aisle, so there should be only a rare
need for the access hatches. These could be covered with lightweight scenery, if desired.

Since many model railroaders aren't nearly this constrained for
space, exploring these ideas and avoiding monolithic rectangles in the center of the room can offer a lot of interesting alternatives.
