Late March: Streetlites arrive for the X66, a few older vehicles withdrawn from service. Namely a few older B10BLEs in the fleet, while the youngest B10BLEs at Riverside take their place at their respective depots.
Mid April: 15 Streetlites arrive for the Lime, 4853/4/5 (by now possibly withdrawn with the younger B10BLEs taking their place at CLS following arrival of X66 Streetlites) definitely withdrawn by this point. 4896 withdrawn too, whilst the 3 in the former X7 batch (4906/8/9) are displaced elsewhere (with the 7 PVR of Chester-le-Street's Lime runs being filled by the new Streetlites and no need for a spare B10BLE, with the spare Streetlite confirmed). 6 B10BLEs at Stanley either directly withdrawn (probably 4897-4902, technically oldest after 4853-55 and 96) or relocated to other depots where gaps need to be filled.
Mid May: 10 Streetlites arrive for Red Kite. 9 branded and 1 spare. 9 Red Kite-branded OmniCities (5234 - 5243) taken away from Stanley and 8 allocated to Toon Link (or whatever it was we were discussing haha) and 1 to Percy Main as a spare. 8 B10BLEs from the Toon Link services directly withdrawn as a result.
My prediction.
