The class 465/0 was the first every southeastern subclass it was built in 1993 and still runs today it would be good in the southeastern route in TSW 2 The 465/0 has no first class.
Don't think this is different enough from the /9 to be needed in game as it stands. Plenty of other 3rd rail units could be made ahead of it and the fact that there's very little railway in game that they run on would detract from it's usefulness for me. Add in the NKL, Sevenoaks or Orpington lines and maybe, but we do already have the /9
Essentially it's a whole new model, but with no obvious difference from the one in game unless you were to scour with the zoom set to max (because you'll know people will complain about using the MetCamm shell instead of the BREL one). Main difference is they've been refitted with Hitachi Traction packs so sound like the 395s.
If the class 465/0 was to ever come to tsw2, it would be much better for it to come with a route that it more regularly operates on such Charing Cross - Dartford or Victoria - Orpington for example.
