RE: Arriva North West - Birkenhead Depot
Unless of course the frequency was changed to 20 minutes giving extra running time and thus extra recovery time for delays - especially if there's a known spot in the bridge for creating a delay. The rest of your arguments stand though and would make such a change likely unsustainable. No need to jump on people for making suggestions though.

What Raawwwrrr! says is likely the case in the aforementioned situation L2SLT.
