Should be the 0750 (M-F only), 1205 and 1615 Alnwick to Berwick, and the approx 10am and 2pm departures back from Berwick. Sat/Sun timings vary by 10 mins or so.

They have been running audio-visual buses on the majority of the above services, but with the vehicle issues recently it probably isn't wise to be promoting something they can only deliver half the time.
