H0 model trains are the most popular size/gauge in the world. The scale and gauge used in H0 trains are have the most real scale gauge ratio possible.
H0 model train specifications
- mm = 16.5
- scale = 1: 87
- Scale foot = 3.5ft
- Preferred radius = 6ft
H0 scale models have the exact size gauge as the UK only OO gauge. This means it is possible to use stock from each gauge on the same track.
The main advantage of H0 model trains is that ready made track and rolling stock is readily available. For beginners H0 model kits are the easiest way to get started with model railway trains.
I would recommend that beginners choose H0 scale model trains and then just ignore the rest. When looking for new trains or track, just look for ‘H0 scale’ as the plethora of scales and gauges can be easily confusing for any beginner.
H0 scale model trains are the most likely gauge that will be stocked by your local shop. Before deciding on a gauge, it’s worth visiting your local model railway shop to find what gauge is the most common.
Having a choice of equipment locally is certainly helpful in the opening phase.
As discussed H0 is model train gauge that is favored in the United States so if you live elsewhere it might be worth checking out OO or N gauge.
