uhh… no, it is way closer… you have to fan the tracks out a bit to get clearance… how much you do is your design.
you can see this in the picture… it’s not much more than the gauge of the track… track to track spacing in a yard is your discretion… I use Kadees, so I can lift individual cars straight up, so you can space tracks pretty close, the closest would not allow you to get your fingers in to put the trucks on the track right, but remove a car.
my advice is if you are considering making a sector switch, and maybe going even more tracks, you mock up 3 tracks in parallel, put cars on them and see what minimum spacing you are comfortable with.
this will boil down to your priorities, i.e. if maximum capacity is the highest priority, squeeze them together so close there is only enough room for your fingers to grab the car/loco.
If your priority is to be able to “fiddle” on the tracks then the mockup can be used to determine the minimum spacing to be able to reach in and re-rail a loco/car.
