more of a bus person than a train person but i do know the NL is a 30 minute frequency. however with that being said, the missus lives in moorside estate (northumberland park) and can see the train lines from her bedroom window

the other day were getting ready to go somewhere and noticed 2 trains, both newcastle bound, in the space of 10-15 minutes. would this be some form of late running or dead running out of service train.

just curious and a bit thrown off when i seen it.
