That should look nice in the GWT I reckon. The Vitrains model is nice, and prices are slowly coming down I think. I've got one of the Blue 47600 in the post, and I'll probably pick up Great Eastern at Warley, they'll both change from original but no prototype has been settled on yet. I'll probably have to put up with 14mil branchlines though for the time being, couldn't fault them on my Vi 37s.
