4/16/23/71/72/72A/87/X63:
"Minor changes to journeys during am and pm peak to provide greater reliability." (or words to that effect).

"0657 journey from Gilley Law to Sunderland retimed to depart Gilley Law 0652 and to operate 5 minutes earlier throughout."
20:
"Service rerouted inbound via the A1231 & Burdon Road rather than City Hall to assist reliability. Minor changes to am and pm peak journeys to improve reliability." (20 has already been doing that route since the end of October so they're just making it permanent)
E1/2/6:
"Minor changes to journeys during pm peak and also between the 1800-1930hrs period to provide additional reliability."
