So I'm trying to figure out how to make the S curve I'm planning to work so I think it would be helpful to see some S Curves. So let's see your S Curves on your layout!
Greetings! I would think there are basically three ways to create an "S" curve that will work OK 1. use curve radius that is large enough for locos and cars you are running not to have a problem with the reversing of curve 2. have a segment of easement coming out of first part of "S" and into the second part of "S" (which could be in radius such as #1 3. have a straight section between first part of "S" and second part of "S" that is the length of the longest car and loco other than that, I would think most, if not all, "S" curves would be problematic Peace, Gary L Lake Dillensnyder
This is the "S" curve that started my layout planning process. It's now the cover girl to the latest McMillan book. The black and white calendar shot of the same spot is what got me started. http://cdn.shopify.com/s/files/1/0072/5972/products/Canyon_Lands_book_large.jpg?119 Location is 'way back' from the road alongside I-40 at Chalendar, AZ. It's also been the subject of a Howard Fogg painting for UTLX. As you can see, it's pretty sharp, and pretty tight, for a mainline, high-speed, double-track situation. It's not as famous as Horse Shoe, but making the book cover is a good step in the right direction. I think it's the most scenic spot on the entire ATSF. And that S-curve is replicated as best as I could fit on my layout.....
Good one randgust... I'll add another Santa Fe one, this time at Glen Frazer. F45/U36C/GP60 team up to lead a double stack Eastbound.
I think it's the gradual easements Jerry built into his ess curve approaches that makes his scenes look so realistic. I wonder if his being an engineer who doesn't like being slammed from one side of his cab to the other as his train enters a curve has something to do with this...ya think? Rand's easements look just as good as Jerry's. Easements really make a realistic scene when viewed through the camera lens.
Here's another one (lower right) amongst many non-S curves: Sadly, no scenery yet. Easements are definitely a key element.
Gary..... that is a fun pretzel. I cant wait to see some scenery there! Better yet. To see how you do it! I also believe that an easy grade is a necessity. Those curves only make grades worse...
Here's the S curve at the bottom of the long grade leading up to the 2nd level.

Can only provide the link. Sorry
with smaller "loop" layouts, I always felt it was critical to get some bend into the mainline to give the illusion of distance and not so obvious oval shape. HuskerN www.nscaleaddiction.blogspot.com
Thanks for the advice and pics! I think I've finally came up with a design for my diorama and here it is. The left side is based off of this Ron Flanary pic http://www.railpictures.net/viewphoto.php?id=423243&nesq=21&favsearch=1 and the left will have a tunnel based on the NS Cumberland Gap Tunnel
