Be aware that a Walthers/Shinohara #6-1/2 is comprised of 24"/18" radius curves, not 24"/20" as advertised.

Has anyone ever contacted Walthers about this situation?   It has been like this for years.

IIRC I contacted them when I first discovered it several years ago but received no response. All their curved turnouts overstate the divergent radii by 2".

Hi Santa Fe Block,

Back to your layout. What I see as a problem is that most of your stub end sidings are far too short, unless it might be for a small warehouse. Those sidings/spurs would only handle aprox. 2 cars. I don't think you would be very happy with that.

Welcome

Silly LION. Him thinked you were making a 50' x 96' railroad. Instead I see that you are using a ping pong table size layout. OK, very good. Yes. more space on your exit, exit from the tangent track.

What are those switches in the middle? Are they Double Slip Switches. That is fancy track work. There are two kinds of double slip switches sold. One has a single solinoid machine, and the alignment is either straigt through either way, or diverging either way.

LION uses the two motor kind: which gives four different routes.

Normal, Normal = Top Left to Bottom Right
Reverse, Reverse = Bottom Left to Top Right

Normal, Reverse = Top Left to Top Right

Reverse, Normal = Bottom Left to Bottom Right

LION uses Tortoise switch machines. Him cut the solinoid motors off of the Double slip switches of him and wuse them with Turtles.

Turtles also make good soup.

If you don't have the turnouts on hand, you could also print out "templates" of the turnouts to see how they work (make sure you have your printer set to 100% before printing -- if you don't, then your printer will automatucally scale it down). A few cents' investment of paper and ink is far better than $40+ investment in an ill-fitting turnout. If the paper mock-up works, then invest in the turnouts.

One other thought: if the Atlas #6 turnout is too big, you may want to consider Peco #6 turnouts. They are the same length as the #4 turnouts but give you the more generous angle of the #6. And the Peco website provides full scale templates of their turnouts.

   From the looks of it placing a curved turnout where you indicate leaves a long stretch that a train would foul the switch. Try placing a #6 turnout one section before the curve to give more room to "get away" from the mainline. If you have the track try laying it out and see if that helps. At worst you may lose a few trees in the grove or move the grove more to the right.

Curve Divergence - Newbie Question.
Posted by SantaFeBlock on Saturday, August 1, 2015 5:07 AM

 

Hello All,

Well here goes my first post, your help is much appreciated here.

Currently I’m planning a freelance 50x96’’ HO layout representing the Inland Empire circa 1925-45. I’ll be running a 2-8-2 Light Mike on the main and a 0-4-0 or 0-6-0 in the yard.

[URL=http://s61.photobucket.com/user/oneill311/media/CACitrp.png.html]http://i61.photobucket.com/albums/h44/oneill311/CACitrp.png[/URL

 Attached you’ll see my layout in Atlas Track Planner. I’m using 22” curves plus flex-track, my question concerns the divergence between the two sections above the orange grove where the circle has been placed. What are your recommendations? It looks to me my only option is a Walthers 6 ½ curved turnout and a bit more of the flex track.

Thanks in advance for the help!
