British N Gauge Grade Tolerance

[scottmitchell74]

My first layout has a frustrating 3.3 to 4% grade. It's very limiting.

On my new proposed layout I want elevation, but I'm only allowing 2% at most.

I'm wondering how British locos handle 2%?

Thanks!

There's no single correct answer.   It really does vary by model, and depends on loco weight, number of driven axles, whether or not there are traction tyres,  weight and drag of the train, whether there are curves on the gradient etc.  I would say British N locos generally don't have traction tyres  

2% is generally considered the steepest to go for, but some trial and error is wise.

Some do and some don't, and even those that do will struggle with long heavy trains. It's best to avoid gradients all together (in your layout plans) and if that's not possible then make sure they are as gentle as possible and not greater than 2%.
