I have 2 Shinohara Curved radius turnouts on the layout
with a 24 inch radius on the main and 18 inch radius on the diverging route
and these locos will derail 3 out of 5 times on the 18 inch radius
But all my athearn 4 axel loco will go thru no problem
Is there a fix ?
TIA

Hi Terry,
I have had nothing but problems with shinohara curved turnouts. Most of my locomotives (either 4 or 6 axle) will transverse the 18" but derail on the 24" (go figure) i've tweeked them until they eventually fell apart. They did work when i put shims of cardstock under them in various spots between the ties and the roadbed but eventually the derailments came back. I've already pulled up three of them and replaced them with #6 turnouts after redoing a lot of roadbed work and have 2 left that suprisingly, haven't given me any problems. If i ever build another layout someday, there will be no more curved turnouts.
Another thing, I've found that the shinohara turnouts will not work anymore if the copper clip at the point rail ever breaks. Once it breaks or looses contact with the stock rail, the entire turnout looses continuity.
The only thing i could suggest is that you do the NMRA gauge thingy to the wheels on the locomotive and try to shim the turnout....chuck
Terry,
I did an experiment a couple of years ago and discovered the radii marked on the Walthers Shinohara turnouts are wrong. The outer radius is very close to being what is marked, but the inner radius in all cases was considerably tighter than marked. If my memory is correct, the inside radius on your turnout is closer to a 16.5" radius instead of 18".

Research; it's not just for geeks.
davidmbedard Gauge your wheels and gauge your track. It sounds like your guard rail on the diverging route isn't doing it's job and you are picking the frog. David B

The wheels on all 4 locos are fine David but the Turnout seems alittle tight
I don't have time to replace it before my open house Sat So i'm gonna try extending the gaurd rail
Maybe i can find a new one at the show

I think you may be right Don
I took a piece of 18 inch snap track and laid it over top of the turn out and the inside radius is just a
little tighter than the snap track
Terry, I sure don't like the sound of that. I just purchased a couple of #6's and #8's for my layout. I have them layed out but not powered so I haven't tested them yet. Looks like that needs to be my next step before I start on anything else.
Does your steamers go through them ok? What about the T-1?

All the steamers go thru> EXCEPT < the T-1
No way will that puppy do an 18 inch Radius
Found out the geeps will go thru the other curved turn out so just this one must be out of gauge
I extended the gaurd rail
Not Pretty but it works
So maybe I can find a new turnout at the show
Thanks all !
