I've finished painting one of the new bogie coaches and the mess van and I'm quite pleased with both of them. The colour I found for the passenger carriages is another Games workshop acrylic called Dark Angels Green, it has gone on pretty well.
The other two are nearly done and I think the rake will look smart when they are all done.
The mess van needs a good weathering to make it look a bit more used but the basic idea is there and will make a nice rear vehicle on a works train. I haven't put a coupling on the balcony end because they look so lumpy, I may find I need to add this in time.
