Reply to "What is a good % for maximum grade"

AGHRMattOGR Forum Member SUPPORTING MEMBERMEMORIAL SUPPORTER

Real railroads tried to avoid grades like the plague, and where they had steep grades they used helpers. At AGHR, we designed the mainline grade at 1.4% and the upper branch line to 2%. It allows for running long trains without straining the locomotives, especially with NMRA-weighted rolling stock.

On this design I'm refining for my garage, the grade on the mainline is 1.6%. The branch into town is 2.2%
