Has anyone here ever made an operating log dump?

Looking for ideas or suggestions on how to actually dump logs off a flatcar,
for my 1:35n2 layout.

I could do a rotating dump like I have for my borax cars,
but that would take up more real estate than I have available.

I could just remove the logs manually, but would like something a bit more fun.

Perhaps a horizontal mounted air ram to push logs off the flat cars.

Photo of an air ram used to dump Granby style ore cars,
at a mine I visited in British Columbia.

I was thinking along the lines of maybe a jill poke. 

But would the cars stay on the rails?

I did find this in Freerails:

Some may be wondering why I'm interested in log cars since I model mostly desert.

Future planned extensions would bring my railroad up the eastern slope of the White Mountains with some limited logging. 

This is probably way in the future but it's nice to occasionally plan ahead.

With the lack of timber in a desert,
bringing in timber would make sense for mine props and building construction.

Have seen a similar operation taking place in Peru,
with Eucalyptus timber traveling over 3 Railways from source to final use.

Perhaps a photo of your flat cars could help determine a viable method to off load.
The photo of the off load system looms like it should work.

I understand real railroads provided a timber "wall" for the cars to lean against,
on the side where the logs would roll from the cars, to hold them on the rails,
when the jill poke or some other device would push against them.

Have seen a chain that would be put under the logs and then lifted by a winch ...
However, no idea how to make this work in a model.

Here is a YouTube video of a large O Scale logging layout which features an operating log dumper.

The dumper is near the end of the video at around the 10:15 mark.

It appears to be easy to make and looks fool proof.

Jack,

Thanks for that You Tube link.  Certainly interesting. 

Something like that just might work for me.

Now I'll have to cobble something together and see how it turns out.

Hi Michael  :mex:

The 'Tri-ang Railways' approach ^^ to log unloading ...  :brill:

... was to have the actual car kinda doing the 'tipping'.


I believe that the 'Lionel' HO ones were identical & made by 'Tri-ang'.  L:


I would say it's worth seeing if you can pick one up 'cheap' to mess with.  :cool:

The trackside operating-device is fairly easy to 'clone', if it is missing.  :P


:java::moose: :dt:


Si.
