I've added some more underframe dirt, but it's not quite right - I bought a pot of buff coloured powder to see if that makes a difference, and at some point I want to gently drybrush the underframe but I'm wary of overdoing it. It did help a great deal to realise that the triangular gussets below the ribs don't appear to be in body colour in any of the pictures, although it looks like I haven't fixed this on the first wagon - it's right on the others though. Still haven't really touched the steps or the handrail.

I've also made a start on two more, this one is supposed to be a little dirtier than the first, with dents/scratches from digger unloading added with a pencil. Looking at the pictures I think I messed up the buff-coloured washes - in my eagerness to stop them collecting by the ribs (which doesn't happen much in real life) I've managed to wick some of the wash off the panel itself and left gaps - oh well. I can probably fill it in again...

The second is based on this prototype picture: http://ukrailrolling.../p14425124.html

of a really filthy one with lots of fresh mud (?) on it. I think I've overdone this a bit but I'm not sure yet - see what you think. Possibly I should take one of the panels back to factory paint and re-do it with much less mud so that the muddy ones look more intentional?

These two both need more work on their underframe, especially the second which has mud spills and things to add.

Finally there's one left in unmodified state. Not sure what to do with it yet. I've also picked up a Railtrack PNA and from what I can see they are usually in horrible condition with peeling paint, rust galore, etc.
