GW MICAs - an overview.

The recent completion of a commissioned X2 MICA B in post-1904 livery prompted this entry, and the accompanying photographs illustrate that model.

Located as it is between the dock and Smithfield market, meat traffic will play a significant part of goods traffic passing through the subterranean levels of Basilica Fields, with the GWR shouldering the greatest load. If, like me, you grew up unsullied by Great Western telegraph code nomenclature, and therefore completely in the dark about MORELS, MITES, MACAWS, MINKS, MOGOs and MAGOOS (one of those is a red herring, and that's nothing to do with fish traffic!), then hopefully you'll at least have some idea of what a MICA is by the end of this mini series. As these vehicles came in so many varieties I'll be dealing with each type separately, so this first entry serves as a detailed overview.

 

Perhaps the most famous of GWR meat trains were those running between Birkenhead and Smithfield via Acton, but there were other services to Plymouth and Avonmouth, as well as one between Victoria Dock and Cardiff via the North London Railway. The Circle & Widened Lines Extension to the docks also gives an opportunity to transport meat from there to Smithfield, and occasionally direct to Acton without recourse to the NLR.

 

Through the 1890s, beef from the Americas landed live at Birkenhead, and after a short period of recovery from the arduous journey, cattle was slaughtered and butchered locally. Their carcasses were then chilled before forwarding to Smithfield - a process taking up to 20 hours from abattoir to market. Ventilated vans were found to be sufficient keep the meat cool for this journey, and for the purpose of Basilica Fields we need go to back no further than the 110 vans built between 1889 - 1891 which were later diagrammed X1 and given the telegraph code MICA. Ventilation was via hinged bonnet ends that ran the full width along the top of the vans with scalloped bottoms to the sides, and a series of 1ft 8ins ventilation slots along the side of the vans on the third plank down. Construction was double-cased tongue and grooved planking with flush-fitted doors and no exterior bracing. These vans were fully vacuum fitted for running at fast goods speeds.

 

Contemporaneously, a batch of 13 vans were built at Swansea Wagon Works for the South Wales Railway and later diagrammed X3 with the code MICA A. These were non-ventilated and were used for rushing chilled meats between Victoria Dock in London to Cardiff. They had ice containers installed and used straw for insulation. The vans were diagonally planked with a narrow cupboard door and were fitted with a vacuum through pipe for travelling at passenger speeds.

 

With the increase of chilled and frozen meat such as mutton from Australasia, a new van emerged based on the X1 design but without the side ventilation slots and having plain bottoms to the ventilator bonnet sides. These vans were fitted with X3-type ice containers which were filled from the inside, and a 3" air space between the double body sheeting provided some degree of insulation. As such, these 240 vans to diagram X2 could be used either as ventilated or refrigerated, depending on the requirement, and were given the code MICA B. Ten further examples of X2 were built without the end ventilator bonnets and coded MICA A, and another ten X2 were fitted with the end bonnets but had no ice containers and were simply coded MICA.

The liveries of the MICAs throws up a few interesting questions which I've not had answered satisfactorily yet, and so I'll begin with extracts from Slinn's Great Western Way pp.97 - 102:

 

Period ending 1903: "It was at the time of the start of the right hand small lettering that refrigerated meat vans began to be painted with white bodies and it is believed that the lettering was black. Photographic emulsions of the time do not differentiate between black and red and no trace has been found in official documents to say which colour was used..."

 

1904 - 1919: "Refrigerated vans had already appeared painted in white but now their lettering was executed in red."

  • Question: Right-hand small GWR lettering was introduced c1893, so what colour were the X3 vans between being built in 1889 and 1893?
     
    I had assumed that the red lettering was introduced with the white livery from comments in other sources, such as Tourret et al.

  • Question: Is there any other source to confirm black lettering was used on white-painted X2 and X3 MICA A and MICA B up to 1904, or did small red lettering in fact appear much earlier during the 1890s?
     
    The whole debate over the colour of general merchandise goods stock in the 1890s also throws up one further interesting query.

  • Question: Were X1 MICAs originally painted red?

The floor is open for debate!

 

The model was built from a WEP brass kit, pretty much as designed, and given a light weathering. Screw couplings and safety chains from Laurie Griffin. Contemporary photographs show these vans got absolutely filthy, no doubt in part due to their journey to Smithfield on the Metropolitan Line, so this one represents a fairly recently repainted example c1912.

Just how many of these "things" are needed for Artillery Lane?

 

Your thoughts suggest that I need to re-read the GWR Paint BIble and then start searching for clues.

A round dozen split between X1 and all three variants of X2. X3 are not anticipated at this time. Few, if any will be in post-1904 livery.

I've no idea about the livery. I've have one of these built in 2mm and know it needs to be filthy, but I haven't the heart to do it after adding all the lettering. The model you have created looks really nice. It seems to show that I have missed the steps off under the doors too.

A wonderful model, but being a Southern modeller my head is spinning in a confused state.

 

Don't worry, as a Great Eastern modeller it's taken me a long time to get handle on the Great Western mindset. However, by the time this mini series is over all should be clear. I hope...

And it's an awful lot of lettering! I don't envy you doing it in 2mm either - even in 7mm it had its moments.

We all know what a fantastic modeller you are, so I'll be different this time and congratulate you on the photography.

 

On the subject of livery, we probably have the same books so I'm afraid I can't add anything. I wonder though where the theory of the lettering originally being black actually comes from? Slinn does not state the origin of this theory. Indeed, he makes a point of saying that no trace has been found in official documents to say which colour was used, and that the difference between black and red cannot be seen in photos from the time. So where does the theory then come from?

 

On a related issue. I assume it is a scientifically proven point that the photographic emulsions of the time don't allow us to differentiate between red and black? I ask because when I look at the photo of the Mica on page 94 in Slinn (original version), the lettering seems obviously red to me, although it is "believed to be in black".

 

The plot thickens when I look at the photo on page 97. Here, some of the lettering is much darker than the rest. In fact, the darker letters almost seem to have been touched up (note especially the "G." bottom right, compared to the "W.R."). If indeed some of these early photos were touched up, could that have given rise to the theory of black lettering?

 

What do I know. But conspirancy theories are fun!

I model a similar period (1900-1910) and also GWR, but in smaller scale (2mm). I am interested in the early MICA vans, though mostly the unrefrigerated ones for the Birkenhead-Acton trains, as I am intending to model the Crewe-Wellington line and I have a picture of meat trains using that line in slightly later years (ca 1920), though I suspect they probably used the Birkenhead-Chester-Wrexham-Shrewsbury.-Wellington lines as their usual route.

 

I've also had a brief and inconclusive discussion on the early livery of the fruit vans, which would probably also be relevant here - were they red/grey/both before they switched to crimson/brown? It's all interesting detective work, trying to draw logical conclusions from incomplete records. Not helped by the habits of these wagons to run in overnight trains, rarely appearing in photographs (and inevitably being "grey" in the monochrome photographs anyway...). I look forward to seeing your discussions of similar questions here.

Referring to the points made by Mikkel.... look at the photos in Hornby and BRM for April.... the photos of model GW and BR(LMR) engines.... the lining. Several of the photos "appear" to show just plain red lining whereas the models have orange/black/orange (GW) or BR mixed traffic lining. Ugh.

Mikkel,

 

Thank you, but I'm a bit of a bodger when it comes to photography. Thank gawd for digital or I'd be well and truly stuffed. All my presentable shots have been taken with a Canon 300D which is now getting on a bit in digital terms, but I do utilise two necessary extras - a Manforotto tripod and a remote switch. I've yet to get a decent shot with artificial light, even bright daylight bulbs and that worries me when it comes to taking future shots of Basilica Fields. I guess I'll be digging deep for some decent floods.

 

Back to liveries; you've made some interesting points.

 

There were a range of photographic emulsions on offer at the time, and yes, they were red blind, but - and it's a big but - not all exhibited the same properties. Going back to matters Great Eastern as I can at least speak with some authority without putting my foot in it, it is almost impossible to see the vermilion lining on +99% of all images which isn't too much of a problem on the ultramarine livery as one can see the blue and black border, but in the past it has caused much consternation with those locos painted black. Both Adams and Bromley's black locos had red lining, and after 1890 all goods engines were painted black.

 

An unofficial painting procedure has been handed down by the photographer and ex-GER employee Ken Nunn, and because of that one document it was long assumed that all black goods engines from 1890 were lined red in the same style as the blue passenger locos, but this lining couldn't be seen on the emulsions of the period. Only relatively recently have we come to understand, from other contemporary sources, that the GER infact pulled a fast one and lined only the lowliest of four-coupled shunters, and all other goods and shunting engines were plain black and unlined.

 

Here's an example of the difficulties encountered. This class of downright ugly ducklings was the first mogul (2-6-0) not only on the GE, but in the UK, and was painted black, lined red, and the cab side number plates were vermilion. See how difficult it is?

 

Back to Slinn's comments about black lettering; I simply don't know enough about the GW, or have the resources to hand to make too many bold statements. I believe a study was conducted to see if the eye can differentiate between red and black on these old emulsions, and the consensus was a resounding 'No', but I don't know if it was particularly scientific in its execution, and I think there is a lot to be said for gut feeling.

 

No. 59972 appears *to me* to have red characters, and both the running number and small GWR appear to be darker. I agree, this may well be down to the photographer touching up the lettering - ye olde photoshoppe! I hadn't made a connection with this practice possibly giving rise to the theory of black lettering, but that seems like a distinct possibility to me.

 

Thanks for your considered thoughts - they are precisely what I had hoped for.

David,

 

Thanks for your input, I've gone back and reread the discussion on your blog. I now know where I saw the information on a study attempting to differentiate between red and black on these emulsions! I'm expecting some more info in my inbox sometime next week, so once I've digested that I'll post it up.

I haven't got either of those magazines Graham, though I will be getting BRM for the Nunstanton piece.
