Or 1cm increase in height over 50cm of horizontal travel. This tried and tested ratio for model railways is a grade of 1 in 50. This predicament has been tackled and the optimum ratio for rate of climb that trains can manage while eating up the minimum distance of track is well established. And on our model railways - where space is a premium - it’s even more of a problem. These include spirals that work their way around hills and mountains, zig-zags and horse-shoe designs. On real railways this is expensive and ingenious designs have been developed over time to provide the length of track required without the distance. The problem is that this requires long stretches of track. You can see this in real railways where the approach to hills is done gradually over many miles. What’s needed is to reduce the incline to a gentle slope. In a discussion on this very subject on the Bachmann trains forum Doneldon noted that building inclines to prevent trains from stalled and backsliding means giving “careful attention to track and wheel gauge, rolling stock clearances, transition curves, moderate grades, electrical integrity, precise coupler adjustments and adherence to correct weight for your rolling stock” (see original post here). Watch James May elaborate on this and explain why trains can’t go uphill: If the slope is too steep there won’t be enough traction to compete with the downhill drag the engine will stop or even roll backward! Given the small amount of surface area on a train wheel that comes into contact with the rails there’s actually little traction that can be brought to bear when climbing a hill. The vertical action breaks up what would otherwise be a dull terrain track plan and adds interest for the viewer, will the little engine make it…īut building inclines isn’t just a matter of titling some track upwards to the height required. I’m changing the track plan so my GWR pannier engines and wagons now climb up to the Tin mine by winding their way around a hill. But seeing your trains hauling up hills, now that’s something else! Watching tiny trains trundling around a model railway is fun but if the track is just flat it can get boring before long.

Here’s how to work out the vital length and gradient numbers needed to start building inclines. If you want a fun and interesting model railway then you’ll want your Hornby trains hauling wagons up hills.
