I wonder if the ones used as barrier wagons had been weighted to balance them up... 

Palvans that were authorised to travel at higher speeds had been retro fitted with balanced springs. Problems still persisted and further testing found that one of the causes of instability was that the van body was too rigid. 

The western region vans modified for pallet ops were only 9ft wheelbase hence no (or accidental) XP rating.

I found it ! Pallet van W114301 at Thames Haven, 1961.

A fair bet that it has been in use to lead Van den Bergh and Jurgens product  (Stork Margarine) for distribution or transfer to another Unilever plant.

... and there's this. Stabled  in their usual spot.

I have a few negs and transparencies of the Kirkcudbright Palvans. Most of them have the legend, "Return to Irvine ScR (GSW)".  Guess who's spent a good bit of time researching Palvan traffic. Lever Bros assisted with the design.

Makes interesting reading regarding the running qualities of the palvan.

I understood the problem as being that forklift drivers just dumped pallets into them such that the load was unevely distributed and they rode so badly as to cause derailements.

Somewhere; I have a report into the investigations into the bad riding and derailments of early Palvans. One part which sticks in my mind was that if, a medium loaded palvan with a un-worn standard BR wheel profile, travelling at above 40 MPH encountered rail depression dip of just 3/8" over approx. 10 foot of rail  (not uncommon at rail joints in areas of mining subsidence) one wheel would loose contact with the railhead.

Two Palvans in the rake of a goods train that became derailed whilst being looped at Eamont Jnc. in 1960 jumped clean over the trains loco and ended up at the head of the wreckage. Having not had sight of an accident report I don't know if the Palvans where noted as being a contributory factor in the derailment.

Don't take the dimensions noted above as definite as it's a long time since I read the report. I'll see if a can dig it out.

"Once seen never hidden".

Along with the other two horizontal tooling lines that Hornby gave us. Maybe they were freebies that Hornby decided to give us in compensation for the missing cladding join or possibly the inside cylinder wheel bosses?

I'll see if that joint can be improved once the B'masters 2MT chassis turns up.

But one particular point to remember please Fran - when these wagons passed through works (and possibly even when they were new?) the inside was not painted.  Maybe some places did bother with painting the inside but I never came across any and over the years I saw quite lot of them, including views from signal box windows, of wagons straight out of shops.

Maybe Shildon did things differently?

Maybe they had some surplus freight red to use up?

Maybe they weren't refurbed at Shildon?

Such a pity this photograph is blurred. At least it shows some 21 ton hoppers were having their interior painted in 65/6.

Then there was the pic of ex works 16tonner, B100925 that showed the inside to be painted but this may have been done specifically for the exhibition it was appearing at.

I don't know about the walkways etc, don't look too bad to me.

Hi Paul,

There’s a good series of photographs on Smugmug showing how the walkways and roof detail should be. It starts here:

https://ukrailwaypics.smugmug.com/UKRailRollingstock/T/TTA-2-axle-tank-wagons/i-fhRSgr9/A

and has walkway gems such as this:

Fortunately for us 4mm scale modellers there is the Stenson etch that will go to some way to making things more correct but should we have to correct things on a new tooling? To be fair to Hornby the quote from their blog was, “The new TTA tanker tooling suite accounts for almost all variants in the 35 and 45 tonne capacities”.

Got to say, I’m looking forward to the 35t GLW TTA’s.

But what manufacturer of frame/brake rigging have they copied? It doesn't look, from the general photo above, like any of the distinctive three designs used by ESSO

This is the wagon they measured at Mangapps.

TTO26E (Ex 6/715) built by Powell Duffryn in 1967.  Looks like a pretty good match to me.

Hth,

It looks an excellent model but such a pity that Hornby appear to be going down the generic route with liveries.

Would have been a world beating wagon if they had got the solebar, walkway & tank top details correct to match the TTO43F diagram. Hornby proved they could get it right when they published photos of earlier tooling variations. I'll still have a couple to retro to the earlier 13 leaf spring version.

How it should have been (with the later parabolic springs).

It seems to me that - compared to DC, (where we have traditionally fed, give or take, 12v DC to our motors and expected them to move forwards or backwards); the innumberable variations of control system, combined with a plethora of different electronics in the models, is bound to make designing models to cope with all this variation an almost impossible task.

Which is why the NMRA have an electrical standard for DCC. Manufactures and individuals can and do modify & deviate from the standard as they see fit or choose to develop there own systems. It's still a developing technology but an interesting one. Some basics of the NMRA standard are followed by all.

t may well be that ESU have included a resistor in the speaker circuit to increase the total resistance to 4 ohms or greater.  Just speculating.

Including a fixed resistance into the speaker circuit should be a bit of a no no. Speaker impedance is dynamic as it alters as the applied voltage increases & decreases to move the air. Previous posters have measured the impedance of the speaker circuit (I assume at the speaker output connection) and found the static resistance to be as expected at approx. 2Ω.

The speakers manufacturer spec sheets clearly state the the speaker is only rated at 0.5 watt so to use it effectively with relatively high outputs it needs to be connected in series with another speaker.

So does this additional bespoke circuitry allow the connection of the speakers in parallel with reduced resistance or is the ESU decoder for the 37 a special that allows for a speaker circuit of lower 2Ω impedance? If it doesn't, at high outputs  (volume), the decoder amplifier will be over stressed and could fail over time.

I'm sure the gents at ESU have done their homework. Funny how they've just introduced a 3 watt speaker with the same footprint as the Accurathrash. Might we see that introduced on the forthcoming A'scale 37's?
