Short line mountain action

[Lester Perry]

Definitely something wrong with the sound - ear-splitting heavy metal.

Nice vid clip, though. What is the actual grade?

I will take a guess at 7%. Not sure though. I wanted it to be limited to 2 cars so I made a 2 car train put track on a 2x4 and started the train moving. I raised the end of the 2x4 until it stalled lowered it a little, there is the grade. Take another look I re-made it
