Recent issues of Invicta have made reference to a darker shade of blue being used for repaints, which from the next issue forwards we're intending on referring to as "2026 Arriva", differentiating from "2017". The "Journey Mark" (or Journeymark, or JourneyMark) designation appears to refer to the original plan for a large Stagecoach-style 'A' on the rear of buses, which was never actually fitted, although the name stuck.
It's a gentle change, designed to be easier to source and expected to be less prone to fading than the original shade. Although it is relatively easy to spot with the eye, it's incredibly difficult to photograph! Low light conditions actually seem to be better at reflecting the difference.
So, although this looks like it would be more suited to a "Mundane in Medway" thread, you'll just have to believe me that 4264 is indeed in the new shade of blue, when seen here in the unmistakable surroundings of Chatham Bus Station shortly after re-entering service on 21st May. The picture also shows off some of the changes to the bus station layout, with the previous two way road here now firmly one way, as denoted by the "no entry" marking under the bus.
