With the Stagecoach Fleetbook due to arrive with people imminently, I can now reveal this year's North East Order:

Stockton depot are due another 17 ADL E300s - this time for services 52/58/35 (allowing the 7 64-reg examples presently used on the 52/35 to be used elsewhere) and services 59/61. At present, it is understand they will NOT be WiFi fitted.
South Shields depot are due to take 19 Euro5 ADL E200s. These will be WiFi enabled (same as 37143/4)

Stockton's 17 should therefore see the withdrawal of the remaining 12 non-DDA MANs in active service at the depot as well as releasing 5 of the DDA MANs into a reserve capacity to replace the non-DDA MANs in that role.
