Re the x3: Sunderland - Newcastle services via Boldon have always failed.
There isn't the demand, no matter which number is in front of it.
Maybe if Boldon had a service to Newcastle which came from a different starting point or via a different route, it may have more joy.
Can't think off the top of my head at the moment, but will try and stick something in the suggestions thread.
