FGW's past plan to use 'Half HST's'
I was thinking about this today, how exactly did they think it was
going to work? I remember reading that before the class 180's were
ordered, FGW planned to use HST's to Bristol and split some of them
into two portions with one going to Weston Super Mare, and the other
down to the West Country.
Of course a very nice idea with some drawbacks...exactly how were they
going to 'split' the train? The other portion would've been facing the
wrong direction to start with, and one portion would've been made up of
one standard class coach, a buffet and two and a half first class!
Exactly how fast are HST's allowed to go without the second power car?
The line speed beyond Bristol is 110mph if i am not mistaken.

Although not *quite* HSTs, the original plan for the XPTs (HST-clone
power cars, Budd coaches) in Australia was that they'd run with two
power cars into/out of Sydney and split/join to serve less popular
destinations, sticking a DVT on the 'other end'.

Presumably power car + 4 or 5 + DVT.

Could somethink like an SR EMU half-cab not have been constructed at the
end of a Mk3 coach, posibly a half-buffet vehicle, allowing a set to
split where the two inner cabs faced each other?
If the train was reformed as two halves :
PC - TSO - TSO - TSO - FO - RMBTSOC
then there'd be no need for shunting bar the actual split/couple.
Back in the 1960s Swindon Class 126 DMUs were built this way, full cab
at one end, half cab at the other, so a 6 car train could run with full
through gangway, but the two 3-car halves could split and run
independently.

The 'Central West' to Dubbo has run from Sydney with one power car and a
reduced formation. They used their depot Shunter to drag the half set into
Sydney Terminal station, it did the usual run to Dubbo where another
shunter dragged the set around a nearby triangle, turning the entire set
around so the power car faced Sydney and then it ran back, to be meet at
Sydney by the XPT depot shunter again to be dragged back to the depot. Use
was made of a triangle near the XPT depot to turn the half set back again
ready for the next trip.
It comes down to 'power to weight' in the end. The sets are also not
designed to be split 'in the field'.

GNER have sent out a set from Neville Hill with a single power car on at
least one occasional. Worked the 0750 Leeds - Aberdeen with the rear
power car getting fitted at Edinburgh Waverley.

It was not uncommon on the ECML in the early days of HST. If turned out from
Bounds Green the set often had a barrier-vehicle BG attached to the rear.

I take it that the sets were dragged into Kings Cross?

I may be wrong but I always thought Bristol - Exeter had some 115mph
and even 120mph stretches.
In IC days, during one of the economic downturns, some West Country
services were diverted away from the Westbury route to serve Bristol.
Much was made, at the time, of the faster speeds possible by this route
such that journey times from the West country would hardly be affected.

I can only presume the same, Ewan, as I only ever saw them at speed further
north, never actually in the Cross.

Something similar was looked at for the North of London Eurostar
services, but designing an acceptable cab and front end was the
stumbling block.
The plan was to have regional half-sets joining/splitting at (I think)
Rugby and Peterborough. There was also a plan involving
splitting/joining Nightstar sleeper services, though this was purely a
loco(s) and hauled stock exercise.

My guess is not. The line to Bridgewater is presumably similar to
that on the other side of the Severn, where ground conditions
prevent high speed running despite ideal alignment most of the way.
I imagine it would cost too much money to raise the line speed.

I think the faster speeds were from Reading to Bath. Presumably
going from Chippenham to Westbury would not save any/much time and
also mean not serving Bristol.

In the old days this would be allowed. HSE now says that a leading car
is to go above 110mph that the front third has to be un-occupied by
passengers to allow suitable crumple zones and ballast to be added.
Hence the design of the Pendolinos and the Voyagers.

Not any longer ITYF. Hence the design of the Alstom Coradia sets (the FGW
'Adelante').

Hmm, Trouble Over Bridgwater methinks?
Could an HST be extended using the outer two coaches of a 442 Wessex
electric in the mddle, which could then be split and driven using the
Wessie cabs? First stumbling block is re-jigging the 442 electrics to
suit the HST 3-phase ac...
