So, in a nutshell, WMR are in the process of polishing a turd? Think the horse has bolted already I'm afraid.
Seriously, both the purple / orange and green / yellow liveries rank up there as the worst I've ever seen. And I've now had the displeasure of seeing both "in the flesh" too, so unlike some here I can't pretend they were "alright" once I'd seen them off the drawing board and in service. They've broken the cardinal rule and regressed on the previous designs of London Midland. And, of course, Joe Public is just going to be confused by their attempts to shoehorn two brands into one franchise, let alone with them now tripping over themselves to rebrand said brands.
This is what happens when you let a bunch of design school graduates sit in a boardroom and pay them good money to do something "bold". Ask any passenger sat at a station where both "brands" run, and they'd assume they were two separate companies, with only a shared affinity for appalling livery design to link them to anybody except us anoraks.
The whole muddle is typical of modern franchise design - they've just ended up nullifying any hope of a cohesive brand and in the process melting passengers' eyes when their garish mess of a train turns up.
... can you tell I don't like their liveries?
