Executed track plan, SLCR

The first layout above, right about at, and surrounding ' j ' , I'd add the 3rd leg of a wye. Otherwise trains, freight cars, locos are unable to reverse direction other than backing up. Backing up is normal on certain types of runs/routes, commonly bucolic branchlines-shortlines, from early steam, to this day. But this track scheme seems more suited to a busy, daily-local, road switcher's line, with trains running both directions by using the passing siding between b and g. I do like the spurs at 1 and 4, the small yard above 3 and the main yard at 6...Several places to depict an interchange..This is saying allot from a die- hard 'point to point', only, guy... M
