Dynamic Track Limitation?

[landnrailroader]

Perhaps Eric or one of you that is more experienced that I can shed some light, or at least agree on what I have just found.

The situation is that doing a loading/unloading loop at Anchorage requires a triple track, very tight curve. Sixty meter radius pieces closely fit the digitized track and that would be the inside track on some curves, outside on others. Another location does not require such a tight curve but it is a best fit for one we do not have and it is double track.

The finding is that the first piece of dynamic, goes in fine, using a +/- 5meter radius value. No problem, vectors show up as expected. Then the 2nd piece goes in (on curves with 60 meter pieces this would be the 3rd piece) and while it snaps on fine, looks right etc. --- EGAD, only the tangent parts generate a vector, none seen over the curve part. I am ass/u/ming that this is a hard error.

I have found that I can fit in two dynamic pieces one on each end of a fixed value curve and while it isn't pretty it works. Apparently the error has something to do with the close presence of another curve?

Can't help on that.... I don't use dynamic track anywhere.

I prefer to not use dynamic also, but the bowl of spaghetti that is the dock area and a few other spots left me no reasonable choice. If anyone down loads the route and wants to eliminate the dynamic track, it is fine with me but you better have some liquid anesthesia at hand first. I have included enough of the Anchorage yards to be usable, though some may want to tweak that area. Right now I am about 75% through Fort Richardson. There are several tracks there which are still in place but one end of them is buried in asphalt, so I assume those are not used. There are 4 long tracks for circus type loading and this is a Armored base, so those are likely used to load tanks etc. on flat cars.

I do find that dynamic is easier to use with TSRE than it ever was with MSTS/RE although I never liked the zig-zag visual effect when you ran a train on it.

I would STRONGLY caution against dynamic track. It is almost a sure fire way to screw up your route beyond all recognition. I had a LOT of it in my first few iterations of my Chicagoland route and after several nuclear meltdowns, and consulting with more experienced route builders, it was figured out that it was the dynamic track that was destroying the route.

Jerry, I've got a bunch of tighter radius tracks that may work for the curved yard. I'll take a look when it's uploaded.

I've never had the corruption issue with dynamic track, but when when it is uploaded, I'll take a look at your tighter curves. The issue I have had, is that if I use, for example, Anchorage yard to start another route, say Anchorage to Fairbanks, then I must delete the dynamic first and reinsert it in the new route. I have done a tracks only version of just abut everything Nashville, TN and did not use any dynamic, and I am using that in at least two routes, but may upload it so others can use it in routes other than Louisville to Nashville, or Nashville to Chattanooga, if they wish.

Dynamic track is a hand grenade in a route, yet even with expanded libraries of track pieces. It almost unavoidable sadly.

After having several route attempts go haywire due to dynamic track, I will forever avoid the use of it. I'll change the curve radius if needed.
thankfully with ScaleRail, there are options that help, especially the yard track sections A, B, C, etc.
