15-inch radius for geared locos?

This is a repeat of a post in the old forum which I can no longer access - apologies if this ends up repeating data.
Does anyone have experience of using Shay or other geared-type locomotives - or a Forney - on curves of less than 18-inch radius? In particular, anyone successfully using European standard 14.625 inch radius curves?
Thanks for any information.

Someone posted a table that gave most, but not all the minimum radius curves that On30 loco's could traverse. I may have had the brains to save that. If so I'll repost it
Nope, no brains! I didn't save it so that I could find it.
Lemmee look once more.
I think you mentioned you wanted to use a Shay on those curves but you hadn't bought it yet? My thought was to go ahead and give it a go as it would be a new engine and bachmann would take care of it if there were problems.
Cheers,

You've got mail!
I wish I could give credit to the original poster but I cannot recall who that was.

I wish I'ld have saved that chart, or at least printed it out. OH NO!
all the the old forum stuff is lost. I did find the Photo bucket still works, &
had the "old forum" pictures in it.

I was down loading it to my trains folder, when I got this message.
Thank you so very much.

Hi Tim,
I guess I owe you for more than just the measurements huh? Believe me I would have given you credit had I been able to remember who posted that table. Good to know that you’ll rework it and repost it. I was going to but as it was your post …. I tip my hat to you.
Thanks again,

Stupendously quick and efficient! Many thanks to all. Anyone care to guess about the Forney's abilities? 18 inch radius seems safe....

18" ain't safe!
I did an experiment using EZ track with straight into curve, reverse curve and full curve. If the Forney ran in reverse ( i.e. tender first) pulling stock through that configuration, you were ok, but running engine first then the rear overhang would cause derailments.
22" is the safest.

Tim's got a good point, but I would stay with at least 22"s.

Thanks for that - good job I didn't order a Forney yesterday then! No room for 22 inch curves, so looks like it's back to the drawing board on loco acquisitions. I wish Bachmann would bring in another diesel model. Perhaps an On30 version of the double-ended rod drive made in G scale?
