GWR top feeds

[steve howe]

I am completing my 'Barnum' after a protracted build, and while fitting the top feed casting I am musing as to what happens to the feed pipes where they meet under the boiler. I am guessing some sort of T fitting with a pipe running back under the boiler towards the cab.

This may or may not be visible on the model, but as I've gone to the trouble of fitting inside motion, it would be nice to get the correct arrangement.

Extremely unlikely.

If you look where a pannier top feed pipes go - they go to the top of the injectors.

Look for where the injectors are on the Barnum - that is where the pipes aim for.

Injectors on Caerphilly Castle for reference.

Isn't there something dangling underneath about in-line with the front step? Could well be one of your feed pipes curving round as the ends point in the right directions. It will probably go under the ashpan as there aren't many other ways for it to get to the back of the engine past the firebox. The 2 pipes would never join - I'll now duck!

There's a straight horizontal pipe down there too, with clip - have you got that one? I'd guess it's the vac train pipe but would expect it to be on the other side with the ejector. Could it be train heat? Interesting pipe along the outside frame which might be but it looks a bit thin.

Could form the basis for a Christmas quiz!
