You need to cut down the connector on the longer piece that you are trying to attach it to.

I have pair of identical Bachmann 4-4-0's that I consisted. I only used one address for both of them. One of them is slower than the other even though they are identical so "like" locos aren't always equal in speed.

Thanks for the link. That was a cool video. I had never seen a real water spout in operation up close nor a coal chute. I imagine that a lot of these procedures weren't always followed by doing them the safe way.

If you have HO track, then you need an HO gauge. You have an "N" scale gauge there.

I had forgotten to include the regular #5 turnouts and the #6 with 1/3 18".  I just redid it with the #5's and #6 with 1/3 18. included.

That's why I said "Close but not exact" and still included them . The other ones are good fits without any "fudging". I know I could have glued the straights but that wouldn't give an accurate picture of what it would be like without the fudging. Some folks can be nit-picky about thing like that.

See the new chart following this post. I had omitted the #5 on this so I deleted it.

I figured the #6 with 1/3 18 would work with a little fudging because it wasn't that far off in Anyrail.

The last one is the #5 wye. There is only one that will work.

With the #5 Wye and one straight leg, a 33 1/4 12* curve is an exact fit.

This is what I get with #4 and 1/2 18" doing like you did with no straight in between. I don't have any turnouts anymore to where I could lay it out and check it.

I'm using Anyrail so I know that sometimes it isn't accurate. I thought the #4 would work with 1/2 18" but when I stretched it out with more straights it wasn't working. I used straight between turnout and curve so I could stretch it out more.

Parallel tracks using #6 turnouts is not possible. A 1/3 (10*) 18" radius will get close but not exact.

Getting parallel tracks with #5 turnouts. It can be done using a 33 1/4 12* curve.

Parallel track using #4 turnouts not possible.
