I don't know why, but sometimes I get this feeling that you don't like IETs▸ ?
No I do not. They represent a considerable backward step as regards passenger facilities and comfort, as discussed elsewhere in these forums.
And now this is compounded by a significant lack of availability whether due to cracks or other faults. Years ago I stated that a single 5 car unit was unsuited to busy trains to/from London. We were told that "all trains to/from London that need to be full length, will be" And what has happened ? 5 car units full and standing on busy services.
Supporters will still claim that they are not bad really and that train length is now less important. But by any common sense standards the project has been a failure.
Timely introduction ? FAIL delivered late.
Japanese reliability ? FAIL, not just the cracks but also overheating, coupling faults, and general poor build quality.
Seating comfort ? FAIL, no doubt some people like them but the general view is of a backward step.
Luggage space ? FAIL, surfboards banned, cycle spaces insufficient and badly designed, as discussed elsewhere.
Catering ? FAIL, none of the promises made about the trolley have been achieved, see the catering thread for details.
Train length ? FAIL, years after introduction short formations are frequent, and that with a reduced timetable.
Whilst they might eventually come right, for how many years are we to wait ? "jam tomorrow" has become "jam in a few years" maybe.
