SE metro fleet composition is a total joke. It should be simplified by proper total replacement.
But this being unloved SE-land we will stay as dumping ground of things nobody else wants for years to come...
It’s a real shame that the Networker fleet has been allowed to deteriorate to such an extent because there has been a “will they, won’t they” question mark over replacement for so long.
The 465-9 interiors are pretty decent, and the older SWR 455s show what can be achieved, even with very long in the tooth fleets. If similar had been done to the Networkers a few years ago they would be far more pleasant to use now.
