I'm quite surprised that this hasn't happened. I was fully expecting Arriva to reduce the 19 to hourly and stick it onto the short 12s as the 12a so that they could discontinue the interworking with the 1/5/5a but keep the PVR the same. That way Darlington would have required 3 less Pulsars and could have gained 3 Optare Solo's from elsewhere in return.   

(For those interested if the 1/5/5a interworked the PVR would be 10 while the 12 and the 19's departing at :46 from Darlington would interwork with a PVR of 3 with the other 19 being 1 bus standalone with a 15 minute layover.)
