I think it makes me more sad than anything, purely because I know just what a slick and user-friendly service SWR Metro could have been had these entered use in the way they were supposed to.
Every few minute frequencies, everything consistently ten carriages (save a few single /5 on weekends) with toilets, air conditioning, charging points, entirely walk-through, little tables for the morning coffee, Wi-Fi, rapid acceleration, a modern PIS, WARM in the winter (big bugbear about the 455s and 458s) and lots of space.
I suppose we'll still get this eventually, but it'll be at least 2025.
