Any errors? A red ! showing? This will prevent the route from totally showing up.
Are you looking in sessions and not the route list? The route won't be driveable until you place a consist somewhere on the route.
To remove the missing dependencies, open the route in Surveyor and choose remove missing dependencies on the file menu. This will bring up a prompt, and confirm whether you want to do this. Usually removing them is no big deal because they're usually textures or something like that, which can be easily replaced.
