Convoy Wont Move

I'm on PS5 and I'm having trouble getting the class 66 convoy to move, service 0057 Peterborough to West yard

 

Release the parking brake in the last 3

 

On both ends of the ending or just the end facing forward? Do i need to start them up individually?

 

Thank you so much! I'm moving now.

 

All locos other than the driving loco

 

Maybe this is a stupid question, but I was playing this service and found it quite enjoyable.

But what would be a realistic set-up to drive the convoy? In Germany, for instance, only the first loco would have its engine running and the other ones would be towed.

If I try to recreate this in game, they are connected and will stop/start their engines together. Even if I uncouple the first and then stop the engines on the other ones, their engines will start again once I couple them again.

I have not yet tried using the traction output, maybe that would be an option?
