Now, why do I have two barrel loaders? The loaders are located in two completely different sections of the layout so I can move barrels from one section to the other section rather than simply unloading them and loading them back into the same car on the same track. I do that with logs, coal, culverts and horses, too.
HTH,

^Now THAT's what I'm talkin about, real loading and unloading scenario's, kudo's.

That being said, I agree with gunrunner, if the barrel loader is vibrating, it's working.
It just needs adjustment one way or another, as another poster put it, shiny "finished" barrels may be too slick to go up the ramp and need a bit of sanding to rough them up. Otherwise, too much vibration will also prevent them from traveling up the ramp, as will to little vibration.
Sometimes you gotta play with it to reach that "sweet spot" where the barrels will travel as intended.....
