I'm not against interworking the 47 if you read between the lines. What I'm saying is that if the reliability of the 47 improves through interworking it with the 45 / 46, then bar 1x or 2x journeys which benefit from deckers (less crowded etc), then the 47 would only need single deckers. Therefore, if 4x extra Streetlites were ordered to the same specification as the others, then the 4x deckers could be put to good use at Chester Le Street and subsequently allow 3962 / 3965 to either go to another depot or allow 3866 / 3867 to be withdrawn at Percy Main.
