Hi Steve,

I am pretty sure Mike is right.

My understanding is that BR imposed a livery requirement of grey tank with red solebars for tanks designated Class A for lighter benzene fuels and all-over black for the heavier fuel oils, designated Class B. This lasted from the 1960s into the 1990s, though I don't know how it originally came about.

The wagon chassis is obviously limited up to a certain weight; depending on suspension, brakes etc.

Because the Class A fuels are lighter, a longer tank is needed to convey the same weight of payload. The heavier Class B fuel oils have the shorter barrel for the same load.

So the longer tanks are grey, while the shorter ones are black. I am not sure, however, why Mobil Charringtons tanks were red! And of course nowadays such colours are defunct; hence the modern VTG wagons we have already done are in a myriad of bright colours!

Cheers

Ben A.

The light colour for Class A liquids goes back well before the 1960s; pre-WW2, a lot were painted silver, which became a light grey (sometimes described as 'Dove Grey') during the hostilities to reduce visibility to enemy aircraft. The light grey continued in use post WW2. Black was the normal colour for anything with a higher flash point, such as fuel oil, diesel (though this was/is often carried in Class A tanks); unlike the Class A colour, it wasn't mandatory, hence Mobil-Charrington's bright red (Mobil's house colour, IIRC), or Shell's bright yellow tanks for specialist oils. Similar colours were often applied to road tankers; I remember black ones with heavy fuel oil for the local power station, and light grey or white for fuel deliveries to garages.

Those CADs show that these will be exquisite tanks if only we can get some more folk to sign up for them. Anyone with even the vaguest possible interest in N, transition era, or just well-executed models will be getting their ears bent by me over the coming weeks.

It is often said that the 00 market is much bigger than N. Perhaps that has something to do with it too. Unfortunately, Heljan prevents a suggestion to shift to 00. Interesting to note that Hugh Flynn (FTG Models) eventually shifted all of his first run of SPA wagons, despite some unfortunate features, and is now preparing CO2 tank wagons. Cavalex is proposing new PGA wagons. It might be instructive to observe how these go.

 

Understood, of course, that your first love is N.

 

Hi ND,

 

You're right, 00 is the main market and as you know we are producing our TEA tankers in 4mm.  We are also planning to offer a new modern wagon at Warley and while initially in N this, presuming people ask us, will almost certainly be made available for backing in 00 too.

 

But for this wagon the 00 market is already well catered for!

 

cheers

 

Ben A.

Ben & Mike - I take it the single pack and triple will all feature different running numbers?

Hi Steve,

Yes, that's correct. So if you order one triple and a single you get four wagons with different numbers in any given livery.

In addition, to make the United Molasses triple a little more interesting one of the wagons will have the original suspension and plain ends, as some did.

It is a shame that this is not being done in 4mm as I fear that Heljan will repeat the errors on their 7mm model!

What were those errors, just as a matter of interest?

The main problem is the tank just does not look right especially around the ends!

I've decided to take the plunge and ordered an Esso triple pack . Even though I current model both OO and O gauge, I'm starting a quick N gauge project and these will fit right in. ( it's a lot easier to hide an N gauge box then it is a O gauge box :D trust me ).

I may even order more when funds allow.
I'm hoping this goes ahead , thank you for giving this opportunity.

Hi Mark,

I haven't looked closely at the Heljan 7mm and 4mm models, and while I take your point about those models having issues in the barrel ends I still think that the majority of the market will be satisfied with these.

I think it is unlikely that another model - even if a better shape - would sell enough to be viable.

Cheers

Or you get more goodies for the same size of disapproval  :mosking:

I am tempted to order a few for a future layout.

Anyone know which of these liveries may have been seen on the South Western mainline around Exeter in the 1960s?

I think you’re absolutely right. I said exactly the same thing about the 00 TEA wagons many moons ago. :sarcastichand:

15.2mm to match Bachmann and Dapol. 

 

Well, yes and no. That is a length that many of the Association wheels are available in, to match the length used for many years by old-style Farish and Peco.

 

However Farish and Dapol tend to use shorter lengths now, to allow a more realistic spacing of the frames. We do plain disc wheels on both 13.7mm and 14.2mm axles, and these might be more appropriate.

 

Should these tankers have plan disc, or 3-hole wheels?

 

Chris

Hi Chris,

These wagons have 3-hole disc wheels, and the axles have been sized to ensure the W irons are the correct spacing for scale 1:148.

ESSO black with a 4-digit number (3xxx, IIRC). The UM tanks didn't appear until the 1970s, whilst any with 5-digit numbers are post-TOPS, so mid 1970s onwards. The bitumen-carrying version of the design, rebuilt with new suspension and air-brakes, was used on traffic to Cattewater, Plymouth, into the 1990s.

We do that too, and with our very shallow points on the axles, ends up at 12.25mm. I'm expecting with the sharper points typically used, yours will be a bit longer than that.

I'd not realised that the singleton has a different number to the triples.

 

Three Essos preordered are now four.

The CAD for these looks excellent and I could Rule #1 a reason to run some in their late 80s 'state'. I'll need to do some investigation into what modelling I would need to do to the unbranded variant before I can commit. Any thoughts out there?

I believe the UM wagons were used to haul spent nuclear treacle to Sellafield until quite late in the 1980s and would have passed through Hellifield. As my interests lie in the East of England I've ordered a pack to represent the flow from the cafe at Sizewell (unofficially Sizewell Tea*) which was mostly the dregs of sugary cuppas but still regarded as low level waste.

† so is this

Fingers crossed these succeed! 8 duly ordered, might try to push that higher but can't commit more just yet.

I've ordered the three of the tank wagons. One in ESSO, one in REGENT and one in unbranded livery.

Just ordered a couple of packs (unbranded livery). Got the 'Gateway' problem mentioned on the site banner, but it seems to be showing on my account OK. I assume the order has gone through?

There are two contradictory statements on the Revolution site which might not help matters:

 

"As with all our products, we will only produce enough to satisfy pre-orders so don’t miss out." http://www.revolutio...s-b-tank-wagon/

 

"All of our products are produced to order, but we are delighted that some model shops have also decided to stock some of our products in case you miss out on pre-ordering" http://www.revolutio...ns.com/dealers/

 

Disclaimer: I've ordered 8.
