Title: Going Up!! - Gradients
Post by: Martin on July 03, 2024, 15:16:50 PM

Calculating Length of Track Needed to Achieve Gradient Required
(this applies to N and 00 as well as other scales/gauges)


Formula:
Height ÷ Gradient = Length

Height:
Height can either be in inches or millimetres (e.g. If height is in inches, length will be in inches, if height is in mm, length will be in mm)

Gradient:
The chosen percentage for the gradient, entered as 0.0X (e.g. for 2% use 0.02)(e.g. for 3% use 0.03) Etc.

Length:
Total length of track needed to achieve height

IMPORTANT
Ensure that the height used, is the distance required from top of rail to bottom of structure (e.g. a bridge) or baseboard, allow enough for rolling stock to pass and access with hand if necessary.
