A CR D34 Trolley, part 1

I’m not a very christmassy person, so it gives me a bit of time to make things. I decided to have a shot at this odd looking thing.

 

This photo has appeared on rmweb before, but if anyone has copyright issues I’ll remove it. Built 1868, scrapped 1917, lived in Glasgow. It is in the diagram book which gives basic dimensions but not much more. Only one built and had the number 1. Should save on transfers.

The original method of construction seems to be flitched. Four heavy timber beams with iron plates each side. The axles with four bearings dropped in from above and then the springs fitted to hold it all up. Unusual, should be fun to model.

 

 

Some parts cut out and stuck together.

It is thought that this wagon had 4’ dia wheels, I have some nominally 3’11” tender wheels which will hopefully work out about right. They run in tubular axles with springs and can be slotted in from underneath.

Progress so far.

It is very light, some sort of load under a sheet will be needed.

Now this is a vehicle that, at 4 mm scale, really couldn't be built in anything other than P4! The Midland (like all the larger companies) had trolleys built on the same principal but with end platforms that more-or-less hide the inner frames and bearings. Mike @airnimal mad an S7 model of one a while back.

 

As to the weight, could you have used strips of lead or steel for the timber, flitched in plasticard?

I think I just about got away with the frame spacing in EM, those are gibson wheels so are pretty narrow. Essentially I adjusted the frame spacing to suit the wheelsets based on the overall width from the diagram. Would look very cramped in the middle in 00 though. 

 

The frames do have a bit of a slot in the bottom, I might see if I can get some weight in there.

Sorry, I had been under the impression you were P4. But the gist of my comment was 00, no way.

That’s a fantastic bit of kit and beautifully modelled. Interesting to see how knarly the tops of the buffer beams are, presumably from end loading very heavy loads?

This will make a very interesting model indeed.

I've loved the look of this wagon, and wondered if I could justify it on St Mungo's, once I get it up running!  Maybe one day, after I manage to make a significant dent in my roundtuit pile!  I think it would be a bit of a pain to cut by hand, so I just may have to save for a Sillouette cutter or similar.  Then again, I can be a bit of a cheapskate!

I have the basic portrait cutter. It has been used a lot. Where it really scores is the ability to cut out large numbers of repetitive parts accurately. For instance those springs are laminated from 3 cuts , thats 24 needed, so cut 30.  Same for the eight sides, cut 10.  All the parts were cut from a single sheet of 10 thou styrene with room for a few strips of 1mm for the angle iron. 

 

I find the silhouette software very simple to use and you can download it from them to have a play about before you buy a machine. 

 

Given that I paid 150 quid for it I reckon it it well worth the money. Less than a rtr loco these days. All the buildings on kelvinbank, lots of wagons , templates for brass cutting and so on.

Lovely styrene work. Although the Silhouette does the cutting you still have to put it together neatly for a convincing look.

 

I've been very happy with my Portrait too, so much so that I recently splashed out on the Cameo 4. To be honest I am not yet convinced it was worth it. The Cameo 4 has a great deal more power, and in principle can cut thicker materials - but frustratingly that extra power can't really be used for the intricate work needed in 4mm scale. Still experimenting, though.

Wow - there is a whole Steampunk aesthetic going on here! I might need to abandon my dreams of coastal Dorsetshire...

Well found Compound, I think it is the D 34. 

 

If it is 1905 then it has had a repaint, the load and the Caley mysterious mark are clearly visible. Looks like it has a new buffer beam too. 

 

Interesting to see those trolleys together like that , since neither has a handbrake.

 

I wonder where it is ? May have something to do with ;

Thanks Caledonian. 

 

For a load it will be something heavy under a sheet. 

 

That photo from Compound is very interesting. I think it is a publicity shot, either for the MR or Stirling Boilers. The boiler is carefully painted, as if it is off to an exhibition somewhere. So the photo either says "we can move stuff like this", or "Our boilers can be delivered by rail."  

 

The CR trolley is 8' 1 1/4 " wide and that boiler is sticking out by a foot, so at least 10' wide overall. Therefore it must have moved as a special over a carefully planned route at fairly low speeds with barrier wagons to provide a handbrake.  Nobody would want it arriving dirty, so I think it would be well sheeted for the journey.

I agree it's a publicity shot. My instinct is it's for the boiler manufacturer - if the railway company photographer did it, I would expect it to be more side-on, and perhaps showing the other wagon(s) in the train, since the one to the left seems to be similarly loaded. This photo seems composed to make sure the writing on the boiler is clearly visible and readable.

Which is either a relief - you don't have to make the fiddly boiler with all those rivets - or a lost opportunity - to make a really interesting thing with lots of lovely rivets!

It is in the LMS collection, which I'm pretty sure means it was taken for the railway - illustrating an unusual load, for example.

Which shows how wrong my instincts can be...

Stirling Engineering are shown as exhibitors.
