Oh yeah indeed about the plug sockets.
I don’t mean fully make them like 385s. But have them as a similar standard, such as new moquette and maybe fabric carpet.
Why anyone thinks carpets on the floors of suburban commuter units is a good idea is beyond me! You only have to see the state of the sets after a weekend to see why it's not a good idea - spilled drink, vomit, urine etc all make short work of ruining even the hardest wearing Industrial carpet! The vinyl in the 380s makes things so much easier and practical for the train presentation teams.
