Stagecoach MCSL - Chester & Wirral Depots

[Turbostar]

RE: Stagecoach Chester & Wirral
When travelling to work this morning on route 2, I noted that a few of the vehicles that were previously on routes 1 & 2 are being used on 41/42 services. I'm wondering if this is part of the plan to put larger (albeit older) vehicles on routes 41/42 on at least some diagrams, pending some newer buses being acquired in the future?
