More seriously now. Ras, do you know for sure 4% is the steepest slope a train can run? Maybe the engine is powerful enough for a steeper slope? Maybe with less trailers to haul? Just my two cents.

it has to do with weight for traction and power. A heavy engine gets more traction but requires more power. I need to at least pull 4 cars
I am really interested in the looping rising circle idea for one side. Has anybody seen or made one for G scale?
I could then use a mountain on the other side
