The only aspect in which I disagree with you is the use of the word "managed", as though there were some element of planning, forethought and deliberation to the decline. In my view MTR and First Group and the individuals in executive management running SWR have completely overreached themselves in terms of ambition and stated objectives, and the race to the bottom has come about due to total managerial incompetence rather than conscious decisions. The franchise bid promised much, but every substantive promise has been executed abysmally. We had strikes within weeks of SWR taking over (for the first time in 20 years, I believe), the 442 debacle, the 458 debacle, the chimera of the promised new timetable, the premature 456 retirement and 701 debacle/farce. SWT management did communicate with passengers - regular "meet the manager"s, and magazines in the Desiros. SWR have bunkered down and hoped no-one will notice.
I watched the interview with the Engineering Director on the subject of the WoE line rolling stock and electrification with interest. The plan sounds compelling, until you consider SWR's dismal record of total failure of any project they have attempted, and the fact this individual presumably must shoulder substantial amounts of the responsibility for these failures. Dubai was built on the maxim of "build it, and they will come", whereas SWR has operated under the principle of "destroy it, and they will carry on working from home".
It would be nice to have more than two fast trains to Surbiton from 5pm-6pm; six were promised in the fabled "new timetable". The New Line would like their fast services in morning and evening restored. Hampton Court and THD punters would like the 19:23 fast restored. I would like it not to be the case that the worst service from THD is not in the 07:30-09:00 period. I understand the current constraints (although it's entirely of SWR's making imo) - some view of the prospects for the future and recognition/responsibility for the pain SWR has inflicted on its customer base would be nice.
