The layout in HO scale, fully sized is not that long, about 34ft in total. But the maximum width of 10.3ft makes baseboards a little tricky.
Even with most of the yard being about 5ft in width, this shows making a layout to scale has implications. I think we will be compressing the width as much as possible, with little need to compress the length.
Standard Gauge train lengths can be 11ft long, whereas the BG cement siding is about 10ft. This is important as it can set the size of our trains. Up to now when drawing rough plans I have tried to include lengthy train capacity. With the scale dimensions this should assist.
