For a livery that is supposed to be a new design and not an adapted version of Intercity Swallow, it doesn’t half look like Intercity Swallow!
I think it looks good. Intercity Swallow has always suited the 91s and Mark 4s, and the Azuma inspired brown actually looks alright in this case. When I first heard “Azuma inspired” I was worried they’d try copying the Angry Birds style red cab ends, which as good as they look on the 80xs would have been utterly hideous on the 91s and DVTs because the shape of them simply wouldn’t suit such a design.
Peel them off? Or else restick them? Who knows.
Ironically peeling the vinyls off the the TFW Mark 4s would leave them pretty much in standard TFW livery, as underneath the vinyls remains East Coast grey, but as mentioned above the black window bands are painted. TFW’s standard livery is of course… Grey with black window bands!
