The steepest recommended gradient is 30 to 1 which means 1 unit of rise (height) for every 30 units of length.

In your case, to rise 8 inches you would need a minimum of 8 x 30 inches, which is 240 inches (20 feet) plus a bit more to allow for the extra drag of the curves.

And further questions such as what scale, steam or D&E traction, what size train loads are proposed, are traction tyres or magnetic assistance acceptable?
