They seem to be working ok each time i have been on them, but in the case of teh class 166's as has been reported before teh air con does need work.
Chilterns class 165's are lovely to travel on, certainly wouldnt mind if they ordered some more class 172's perhaps for the London Marylebone - Oxford services and displaces some class 168's for the Alyesbury route so that we could have a few of them down in Bristol (providing they fit of course.)
Mind you, i doubt they would fit at the platforms at Bristol TM‡ which are under the large roof.
Chiltern plan more loco push-pull working for Birmingham services to release 168s for Oxford, not more dmus.
The 168s have a different body profile to the 165/166s, as the 168 is basically a class 170 configured to couple to 165/166 type-stock, so the body is five inches narrower.
And the extra width in the 165/166 body is at waist height, not at solebar level, so unlikely to be any reason why they would not fit on the platforms in the Temple Meads train shed, given that
HST▸ /Voyager vehicles are allowed, unless something below the floor fouls the platform walls.
I don't know which platforms they used but there was an Oxford-Bristol TM through service operated by 165/66s for a while.
Was normally worked only by two-car 165s. If Oxford was short of a two-car set for other duties the Bristols were liable to get cancelled. See

I've said it before, so I'll say it again. For all the people that say what a good thing it would be, the actual numbers using those trains when they existed were low, often pitifully so. Such a service would only make sense if there were intermediate stations, unlikely to be served by high-speed services, such as Milton Park, Wantage Road, Wootton Bassett and Corsham. Current connections at Didcot certainly leave a lot to be desired much of the time but there has never been a groundswell of opinion demanding the return of direct trains, nor was their loss much mourned.
