Path looks right, but keeps showing error

I am developing a scenario for the NEC. Having a problem I'm not sure how to correct.
I am bringing the player-driver engine out of Race Street yard, to a scenario marker reverse point, and then backing up to Philadelphia 30th Street LL track to hook up to cars.
The reverse marker is showing DIRECTLY in the path of the engine, and is not on a switch. When I add the stop point, I get the (!!!) error saying it can not route a path to the reverse point.
I never did a scenario before that had shunting in before, so I'm not sure what I may be doing wrong.
Thanks for your help
