The first step was to get the line in for the Wood Chip Mill which is now independent of the yard ladder and track work. This is the first curve for the yard and it sets the minimum radius, the radius for this track is 28"R and is the minimum.
I use a Ribbon Rail - Alignment Gauge to set the first curve. The remaining yard tracks are set from the first and are spaced at 2" (50mm) centre to centre. Once the first is set its a matter of measuring from the first track.
Next stage was to check if the yard ladder, and escape track had enough room as per the plan. I placed the yard ladder, runaround track and measured the end escape spur before anymore track is permanently installed.
Next stage is to place down the cork sub-roadbed and install the yard tracks...
