OO gauge (1:76) and N gauge (1:148) are the two most popular scales for UK model railways, and the right choice depends less on "which is better" and more on what you're trying to build. Here's how they compare.
Space
N gauge is roughly half the linear scale of OO, which means a layout that would need a full room in OO gauge can fit on a much smaller board in N gauge — a real advantage if you're working with a loft, a shelf layout, or a smaller spare room.
Detail
OO gauge's larger scale means more visible detail on locomotives, rolling stock and scenery — ladders, pipework, individual bricks and panel lines read clearly at OO size. N gauge scenery is necessarily simpler and smaller, but modern kits (including ours) still carry a good level of moulded detail for the scale.
Running longer trains
Because N gauge takes up less physical space per scale-mile of track, it's easier to run longer, more realistic-length trains — goods trains with a dozen-plus wagons, for example — on a board that would only fit a much shorter train in OO gauge.
What we stock
We carry scenery for both scales. Our OO gauge range is the larger of the two, covering bridges, buildings, walls, industrial and lineside detail. Our N gauge range covers station platforms, girder and arched bridges, and platform detail — most of our N gauge platforms are designed to fit Kato Unitrack directly.
Can you mix scales?
Not on the same layout — the track gauge and model sizes aren't compatible — but plenty of modellers run one scale for a home layout and a second, more compact scale for a portable or exhibition layout. If you're not sure which to start with, N gauge is usually the easier starting point if space is tight, and OO gauge if you want maximum detail and don't mind the larger footprint.
