HST's are units!

The only reason the Power Cars (Driving Motors) are now class 43 is because they where numbered in the coaching stock series.

40xxx - Catering Vehicles
41xxx - First Class Vehicles
42xxx - Standard Class Vehicles
43xxx - Driving Motors (ie Power Cars)

Added later but in the same series...

44xxx - Trailer Guard Standards

Does anyone know if there were and major differences between Class 253/254?

The only 2 I can think of are the 254's being 2+9 and the coaches having stronger windows. (to stop the glass being sucked out when 2 units passed each other at speed in some tunnels)

Haha. So you claim to be able to confirm HSTs are units but don't know if there's a difference between 253s and 254s.

Back to the creche.

HST's are, more or less, glorified DMU's.
--- old post above --- --- new post below ---
And, he is right:
When built, from 1976, the InterCity 125 rolling stock was considered to be diesel-electric multiple units, with semi-fixed formations of power cars and intermediate passenger-carrying trailer cars. They were all numbered in the 4xxxx carriage series set aside for HST and Advanced Passenger Train vehicles. Numbers followed those allocated to the prototype Class 252 unit, so power cars were numbered from 43002 upwards. Class 253 were Western Region 2+7 (two power cars and seven coaches) sets operating out of London Paddington, Class 254 Eastern Region 2+8 sets (with a second buffet car) operating out of London King's Cross.[1][2]
However, because two power cars carried the same 'set number', problems arose when for servicing reasons different units were used on a train, which would then display a different number at each end. For this reason, British Rail abolished the initial numbering system and all individual power cars became identified as such, using the format 43 xxx - this number was previously carried in small digits in the bodysides, prefixed by a 'W', 'E' or 'Sc' to identify the region, thus the power cars were reclassified as Class 43 diesel locomotives and the trailer cars as hauled Mark 3 carriages, collectively known as an InterCity 125. Despite this change in designation, no power car or carriage was renumbered.

Erm, NOPE. He is incorrect.

No such thing as "coaching stock series". Locos/MU vehicles/coaches all have numbers below 99999.
And 254s were 2+8 and 253s were 2+7.
I think there was an issue with window glass, but nothing to do with length of set, more that it wasn't a problem on GW as there is a greater distance between tracks (legacy of Brunel's broad gauge) than on ECML.
So only became apparent when they were introduced on ECML.

That is just being picky. Getting close to clutching at straws. It is perfectly obvious what he meant, even if the correct terminology was not used.

You dug up an old thread just to state something that everyone will argue over for days and days?

What that he was one coach out? :roll: I think my above answer still applies.

I evidently see it as that, I wouldn't have posted it otherwise.
Then why did you say he was incorrect if you actually knew what he meant?

Ralphchadkirk is correct.

43034 The Black Horse your comments about the GW track intervals and the glass are incorrect.

Common to popular belief, the track intervals on the GW are tight in comparison to the standard intervals. Certainly tighter in some cases than the GN main line.


I notice that Wikipedia have used some of my previous posts as the basis for the article.

Like 37401 already stated, what is the point exactly in digging up this old thread, only just to start arguments again, as usual! :roll:

Now that we (or you) have dug up an old thread to flog and there's already a flame war on :), let me stoke some more:

Is there any credence to the claim that the different HST train sets would have been also named as "twins" (253xxx with "Cameron" and "Clegg" power cars) as opposed to the normal loco naming that was eventually adopted?

Just to stir it a little more, class 92's.....
Cant couple to mk2's (if this still applies?). I think its somethong to do with the coridor conections and/or the lamp irons. Also they have to have mods on the ETH supply before they can provide for standard coaching stock, does this stop them being loco's?

Le shuttle loco's. are they locos? Never worked with anything apart from the shuttle sets. Are they locos?

Number series, each Vechicle has a TOPS id that is 5 figuers this is an Ident number for the computer system only. DMU vehicles in the 572xx series dont show up as locos due to them having a different ID number than say a 576xx. My personal thought is 43xxx vehicles are a loco with a desiganted train.

Definition of locomotive....
•The power unit of a train which does not carry passengers or freight itself, but pulls the coaches or rail cars or wagons; A traction engine;

Oh, FFS...!!!!!!

Mod, please can you lock this. It ran to 9 pages the last time around and I fear it's going to go at least as far again. All the salient points on both sides of the arguments are already included so I really see no need for this topic to continue.

The same could be said of a number !

Come on old chap, lighten up. Nothing like being told all about a train you were trained on and worked with, by an adolescent whose (very) fixed opinion is based on what they believe to be the case. :)

There actually was an incident involving the windows very early on just after the HSTs were introduced on the WR. I can remember seeing the press reports at the time.

If I recall correctly, a vandal dropped a stone off a bridge just as two HSTs were passing each other and the stone hit one in such a way that it bounced between the two trains and smashed, I think, a total of 19 windows.

Until the vandalism was ( very quickly ) identified, it was feared that there might have been a design fault on the trains.

Fair enough.

Well, everything I wanted to say on this topic has already been said. If anyone is interested in my opinion, go back through this thread and read it all there because I'm not going to repeat it (again).

Carry on.

in the 90's everyone would avoid bashing hsts and complained when they replaced engine and stock, but when all engine and stock have dissapeared hsts are the bees knees and are new engines and stock,get in the real world the privatised railway is full of units, and the hsts were the first high speed multiple units around (demus) like it or not its the truth :D

Argh, who cares if they're units or not?

Everyone who wanted to venture an opinion has already done so many times. It's all been discussed/argued over for years. Bringing it back up helps no-one!

I like to think of them as a HSDMUL, High Speed Diesel Multipule Unit Locomotive Train, Pleases most people then as its a Loco unit and an independent type of train all in one

Good Lord, no, not at all.

I think you made a very relevant post.

The only only observation I would make is that you appear to have been slightly misinformed on the comment about the windows.

The windows were actually double-glazed with separate panes, inner and outer.

As I remember without checking my old books, the single glazed set was restricted to 100mph to prevent a failure to the window, there was also an occasion when the vehicle was locked out of service but I am unable to remember the exact circumstances without giving it more thought !.

It was thus not the window system per se that was a problem, simply the fact that the system was designed for two panes.
