Precisely. I personally see a clear bias. Everyone wants to complain about the 80x reliability because they don’t like the Fainsa Sophia seats and they don’t like the fact they replaced HSTs, or whatever - everyone seems to think the sun shines out of the FLIRTS gasboxes re. interior and level boarding etc, and thus ignores the fact the 755s were terrible bedding in (thankfully way more of them ordered than diagrams need), the 745 availability is poor, and here in Cardiff the 231s are being taken out of service and swiftly swapped with other ones daily. Almost all Rhymneys are being delayed with Ruth citing it as “more trains than usual requiring repair”. (As 150s do not work on the route anymore, this is nothing to do with 175s, btw)
Would have been very interesting to see how reliable the formerly planned 755 worked Lowestoft Londons were.
