Train network

Hey Captains, hoping someone can help me with my issue.

So I have 2 train stations, 1 loading rock and 1 unloading rock.

On the normal line system everything works, the train picks up the rock and unloads at the offload station.

But I want to add 1 more train, so I thought I would try and use the new network system, I watched some videos on YouTube, off I go but it's not working........

So I am trying to get train 1 to load the rock, while train 2 sits in a waiting bay, as soon as train 1 leaves, I want train 2 to go into the station and load the rock.

I've tried everything but it seems I can't get this to work, train 2 is just sitting in the waiting bay and is "waiting for a job" train 1 eventually comes into it's waiting bay and just sits and the same message for that train.

Any help would be appreciated I have a discord as well, currently at work so can't check anything right now but it have a few screenshots if needed
