Rear-engined bendy buses are a modern invention - there's some
ridiculously complicated hydraulics and computer control in the hinge
to stop them jacknifing constantly. It's a miracle they work at all,
and I can well imagine the system can't cope at all with icy roads
(or
more specifically, the centre axle losing grip and sliding sideways).

Check the list of icy European countries and the number of years
rear-engined bendy buses have operated in each ?

Front-engined bendy buses have no such concerns, as they're no
different from an ordinary single decker with a trailer.

Or Artics, which which were required to add anti-jacknifing hydraulics
twenty years back.

Mr Thant gurgled happily,
sounding much like they were saying:

I must have imagined catching them in Sheffield in the very early '80s,
then.

Definitely rear-engined.

Actually you couldn't be further from the truth. The articulated joint
(manufactured by Hubner) is very simple comprising of a large centre
rotating bearing and two self contained hydraulic rams to passively
counteract the jacknife effect.

The same unit is fitted to both the Scania and Volvo bendies.
The computer control is to let the front half know where the back half
is going so the engine and ABS systems can apply power and brake in the
right proportion.

yes but happens if the bus gets into a bit of a slide or cannot get
traction going round corners, something some of the drivers don't seem
to have mastered in dry weather ?

I've never experienced that, and I was writing on the basis that they'd be
using appropriately trained drivers.
(silly old me, huh?)

I can't remember if it was a bendy bus, but I missed a train in Geneva
one winter because the bus I was on had hit a parked car.
