Inside motion for Manning Wardle Old i Class

Recommended Posts

Just starting to think ahead to my next project, which will be a Manning Wardle Old i Class, for which I am having a go at producing a set of etches for. As there is a gap between the boiler and the frames, I want to include the inside motion for it to prevent it looking 'empty'. I do not currently have any engineering drawings (only scale drawings) - the question is, what type of inside motion did they have? I'm not massively knowledgable (yet!) about the inside workings of locos, so apologies if this is a daft question!

Thanks! This drawing will be really useful :-) Anyone know the name of this type of motion?

I volunteer at the Rutland Railway Museum 'Rocks by Rail'

There is a Barclay, 'Sir Thomas Royden' with inside Stephenson link motion.

 

I have only taken the one photo of it so far, but I will be in, up, over, and under it at the weekend if you would like some more

This was taken from the side of the loco, and sows what can be seen under the boiler.

 

Regards

Hi Ian,

Yes please, that would be more than helpful!

Thanks,

I've been doing a bit of reading and research around the inside stephenson's valve gear, and understand how it works. Constructing one is another matter though! Does anyone know of a kit available for it? Possible not, as I guess they're all different sizes based on whichever loco they are used in. Laurie Griffin Miniatures do a working one I think, but I've no idea if it comes with assembly and fitting instructions or if it's simply a bag of well-cast parts.

I haven't forgotten the photos.

 

Unfortunately, I did forget my camera on the day that I was Loco Cleaner, and she was already off the pit  by the time I got there on the Monday, so there was no opportunity.

 

I will take some as soon as I can, and upload the here for you, though.

 

Regards

 

Ian

The rest will have to wait 'til tomorrow as I have exceeded my 10MB limit.

 

I knew that I should have resized them first..

Ian, you are a gem! Many many thanks. look forwards to the others tomorrow! As an enthusiast, but one with very little knowledge of the 'insides', these are the places I don't normally get to see....

Thanks again, 

John

I think that I can squeeze the rest in without exceeding my limits!

If you need any others, please just shout.

 

With luck, the other Barclay on the roster should be in steam soon, so I can do a comparison set.
