I tend to repeat certain track plans or layout designs. I get fixated on a particular arrangement or a line. Above is what I’ve been drawing and redrawing over the last few weeks.
It’s based on three turnouts.
Cars enter from “interchange” to “loop” and from there are delivered to “customer” (most of the time) or “team track” (every so often).
The scenario is based on those industries you already know I favour where our focus is feeding cars in a conveyor fashion like at a grain elevator, salt unloader, or maybe a new propane dealer.
The plan is a thin, linear design as I always favour. It’s size is determined by these simple geometric principles: the turnouts are equal in length to the lead on the far right (so, in HO this might be around 11”). Multiple that length by three and subtract that from the available shelf length. Then divide that by three.
