RedRich, on the point of knuckles within rakes and tensions on the ends, I do the exact opposite. reason being, my layout has some tight curves and the closer knuckle couplings can lead to buffer lock, especially on the cravens I find, but on the ends I like to have them because they look neater on stabled rakes and on locos I think. it would be good if new models came with a set of each type of coupler
