Finally after almost forty years a question has been answered!
Why are buses fitted with Voith DIWA Transmissions so fucking noisy?
Screaming and humming:
Aha! This is probably why… only encountered these as a driver a couple of times:
I prefer the Semi- Automatic Leyland Pneumocyclic or Hydracyclic family- Wilson types related to WW1 Tanks…
Or the ZF Ecolife.

Oh dear Pt 1:
Oh dear Pt 2:
I know this route very well. Used to drive it. fucking tight especially when encountering a Tourist Coach or Delivery Lorry…

Bloke needs to have a wash 
Reminds me I’ve still got to try the day out on Britain’s rarest bus service. The 112 from Tavistock to Dawlish and back. Miss the September one & you’ll wait 6 months for the next.
I need to drive one of these B43 Tigers before fucking off.
The interior is absolutely amazing; a posh coach for it’s time.
I think I’ve got a Buses Magazine wit a feature on this when it was new!
Apart from the non- matching “Dinner Plate” front wheel trims- round type original design on the N\S\F and later square edged ‘diamond cut’ type on the O\S\F…
It’s bang on.
The suspension design on these is amazing. Not too soft and it is relatively simple- Air over Steel using the Steel Leaf Springs to locate the Axles in the usual way.
No ‘Panhard Rods’…
I’ll grab a picture to show this…
The leaf spring is clearly visible. So to is the ‘H Frame’ that carries the wide based* air suspension bellows and vertical dampers.
The front suspension is similar; the 'bellows sit somewhat inboard- they’re mounted to the inner part of the Chassis Frame. Not the Outriggers seen here.
*No costly ARB needed on the rear axle!
No leaf springs there.All I see is a cast inverted vee used to to mount the axle to and to reduce the ride height.
Minibus road trip
One for @MonitorGold10 - my personal-archaeology nostalgia rabbithole chucked-up this image just now:
If you really know your stuff you’ll know there’s only one area the photo could have been taken, and it’s definitely not anywhere near the route board of the single decker…
The date is 1966 (yeah, baby!) and it hadn’t previously occurred to me that the whole transport nostalgia market was in full swing nearly 60 years ago, but of course it was.
Anyway, very much in your specialist field this one, and still extant of course.
It looks like a Bournemouth Trolley’ to me. Distinctive yellow livery woth maroon stripes. I don’t know anything about Trolleys…
I would be interesting to learn more about it!
The diesel single decker is a Leyland Tiger which I think is owned by London Transport Museum and is based in Acton Museum Depot.
I wonder what it was doing on the South Coast!
Yep - Bournemouth Corporation used a variety of makes, think that one’s a 3-axle Sunbeam. Definitely the 
that’s out of place - seems it was on a heritage tour way back in '66. Given Hants & Dorset were still using double deckers of similar vintage, it’s all the more incongruous!
Rode on many a trolleybus when I was a kid - smelled much better than the diesels of the day. They had a couple of Sunbeams with open tops - interesting being up there hearing it fizz and crackle, and occasionally getting showered by sparks at junctions!
What an incredible looking thing. Boy have we lost our way
