does anyone think that these will ever get another referb or is that it for the hst's I think that this will be the last refurb the HSTs▸ will see relex109. They have however been done to a very high standard whether you like the seating or not as each carriage and power car was stripped to it's shell and virtually rebuilt so they will last until IEP▸ is fully launched and beyond. I believe its safety legislation that will stop them being used after IEP is introduced. Can someone explain further on this one? My advice is enjoy the HSTs over the next 6-7 years and hope Hitachi deliver something that is near to the quality of the HST.

British Rail achieved the current official world speed record for diesel traction of 148 mph using a 2+5 Valenta-engined HST▸ set, although Spain and Russia have claimed unofficial speed records much higher, with 168 mph in the latter case. I think I'm correct in saying that given the opportunity HSTs would quite happily rattle along regularly at 140 mph, given enough time and distance to accelerate.
As far as I know no-one's had a punt at the speed record using an MTU▸ -engined HST set. A possible PR▸ opportunity there methinks, if anyone from FGW▸ Towers is listening... I don't doubt for one moment that the HSTs still have it in them!

The MTU▸ engines are downrated (by as much as 20% I think) on their design power output so that they pretty much match the old Valenta engines in performance, but save fuel, engine wear and noise. If they were allowed to run at full spec then that record would be under serious threat - the H&S▸ red-tape that has to be cut through for any such record attempt is rather amazing though!

Interesting thoughts, I would think the H&S boys would cause a world shortage of red tape if anyone said we want to see if a MTU HST▸ could do 150+. It's very interesting to contrast the French attitude to rail speed records ever since WW2, of course they use specially prepared locos and TGV▸ sets and with less traffic and bettter track they can go for it as per the recent record on the new LGV▸ Est. They celebrate it as a national engineering triumph.

The story of 4468's world steam speed record (126 mph) on the LNER» in 1938 is pretty hair-raising. It doesn't sound like the operating department wanted the civil engineers to find out what was afoot: right up until the day the operation was dressed up as brake trials, and after Mallard had thundered down Stoke Bank at 126 it turned out that much of the track she had run over at that speed consisted of thirty-foot jointed rail, laid almmost 30 years previously

I don't think Sir Nigel Gresley wanted his directors to know what he was planning either Mallard cost ^8,500 to build a substantial amount of money in 1938. Gresley was quite particular picking Mallard for the run she had done a number of miles so was worn in but not overly worn; I had heard that Mallard had to be effectively rebuilt after the record run because of the mount of damage done to bearings etc.
I am sure the re-engined class 43 with a short rake of coaches could turn 150 MPH but what would it prove

The Wessex Electrics hold the third rail record. Has that been "unofficially" beaten?
Why did SWT▸ get rid of them? They're better than the unreliable Junipers, and would be nice for Portsmouth commuters.
At least Southern have got some running again...

They were too expensive to lease.

This was a very unpopular move with passengers on the Portsmouth-London line as SWT removed a number of their 'Intercity' style class 444s off this route to cover the 442s coming off lease between London-Bournemouth-Weymouth line replacing them with suburban 450s on the Portsmouth line which are not suited to long distance travel, bit like Voyagers when you think about it! I like 444s but they aren't as good as the 442s as they were Intercity standard because they were based on Mk3 coaching stock.

Took a trip on NXEA▸ the other week - HSTs▸ with the original seat arrangement and carriage furnishings! Fantastic. Didn't get to see what the engine was as the service was disrupted and the trains were running haphazardly with no CIS▸ information was available so I was wandering in a daze around Liverpool Street and ended up on a random train.

You must have been in quite a daze as NXEA dont have HSTs !!

NXEA▸ do have Mk 3s although I am surprised that plymouthian didn't find his ' HST▸ ' a little quiet. Just to muddy the water, I believe that as far back as 1931, a German, Zepplin built railcar with a petrol engine achieved 142 mph. This speed was surpassed by a (pre-production?) HST which clocked 143 mph in June 1973, still a world record.

A triumph for British/German engineering and one up on the French. But then again I don't think they'd want a diesel record, they are very happy with all their electric records.
