As the layout is pretty low, it's comfortably within my reach. Only this corner and the two 'peninsula' branches are this wide.
There are sections of the loop that are 1 foot wide (mainly at the top and bottom of the loop)
The trade off tho, is that in this yard, I have 6 storage sidings, 2 per way sidings, a 3 road shed and a fueling siding all running parallel to the double track mainline.
it's a little crowded, but then the idea is to get a busy yard feel...
