OK much better w/o switchbacks! But put the run arounds next to yard ladders & get rid of Xovers in the yards. That will give you two more spurs in each yard for more car storage. Also add a R.I.P. track by engine service for car repairs. It'll add some more switch work getting BO cars to that track! Heck even 0-5-0 them there remind yourself they need YOUR fixing. >)
