I like their RWS liveries with their TVS numbers.
I prefer duck's TVS livery with the number 8, but think Oliver's TV livery with his RWS number doesn't look bad.
I prefer their RWS livery, with their NWR numbers of course.
I prefer the second row.
I'd say 2 (TVS liveries and numbers) is actually my favourite; makes 'em feel more like members of the NWR and I prefer the brighter colours.
