Hello all, whilst doing heads out on a HST from Newport to Cardiff, on leaving Newport tunnel something shot past that looked interesting so I shot over to the other window to see I had just passed a train with a class 47 on the rear heading east.... anyone know what I saw? I think it was hauling something network rail related as I when I saw it past I saw bright green and dark blue colours..... anyone who can expand on this working - I was pretty shocked to see a 47 either way!
