Basically, yes!!
About the track switch also, The area above the track switch is a brake zone. So there a lot of things going on there. The ride computer has to check and see if the area is clear to rotate the track switch and the train is in proper position before it rotates it, and then after to make sure the track switch is locked and in proper position. Then it has to make sure the brake zone ahead is clear, before it will let the train go. So if they are slow loading or unloading, you could be up there for a while.
